Abstract
The device for holding an implant (1) comprises an adapter sleeve (300) and a manipulation component, the adapter sleeve (300) being provided for the temporary connection between the implant (1) and the manipulation component. The first end of the adapter sleeve (300) is pushed onto a plug-in projection (10) of the positioned implant (1) in such a manner that it can be detached again; the tip of the manipulation component can be attached to the second end of the adapter sleeve (300) in such a manner that it can be detached again. The implant (1) is taken hold of by attaching the manipulation component to the adapter sleeve (300), which is already connected to the implant. The result is a double plug connection between implant (1), adapter sleeve (300) and manipulation component, thus allowing the implant (1) to be transferred, as it were, without being touched. When the manipulation component is pulled off the implant (1), only the plug connection between the implant (1) and the manipulation component becomes detached. The device can be used particularly advantageously to construct a sterile ampule, thus simplifying the instrumentarium and the use of the ampule during implantation.

Device for holding an implant, an osteosynthesis part, an a~~ociated build-up part or an in~trument Application area of the invention The invention relates to a device for holding an im-plant, an osteosynthesis part, an associated build-up part or an instrument by means of a manipulation compo-nent. Possible implants are screws, pins and nails used in bone surgery, and therefore also in dental surgery.
The osteosynthesis parts here also include plates, for example those used in the maxillofacial area. Build-up parts are understood to mean abutments and prosthetic suprastructures. For the sake of simplicity, all these parts - including the instruments to be held - are for the time being referred to only as implants. Manipula-tion components are implantation tools, transport means and instruments for holding.
The invention can be used in the production of im-plants, to prepare them prior to surgical interventions and during the actual intervention itself. The princi-pal application area of the invention is when the im-plants must not be taken hold of, at least directly, by the hands, for example because it is necessary to use a sterile procedure, and when it is important to hold the implants safely, but also to release them again quickly and without additional tools.
A concrete example of the use of the invention is an ampule for the transportation and storage of an im-plant, in particular a dental implant, which is inten-ded to be inserted - e.g. screwed - into a receiving bore which has been prepared in the bone. The receiving bore may be a threaded bore, or else the implant has a self-tapping thread. After opening, the implant can be removed from the ampule during the surgical interven-tion under sterile conditions using an attached tool, and can then be inserted into the receiving bore in the bone using this tool. Preferably, the ampule can be opened by removing a closure cover. In order to ensure that the procedure is sterile, it is usual to store the ampule in a secondary capsule until the start of the intervention.
Prior art Various manipulation components are known for handling implants, in which the implants are taken hold of in a form-fitting and/or force-fitting manner. This results in the difficulty that the implant can only be taken hold of reliably at high instrument and manual outlay.
At the same time, releasing the implant is more complex and, in addition, there is an increased risk of conta-mlnat lon .
Based on the concrete application example selected, the situation is as follows in the case of ampules, whilemaintaining sterile conditions. There are two fundamen-tal types of ampules. In a first type, the implant stored in the ampule is connected to the cover, which, directly or indirectly, at the same time functions as the screwing-in tool and is used at least to some ex-tent to screw in the implant. According to US-A-4,856,648, in its simplest form the cover has a projec-tion with a non-rotationally symmetrical engagement contour which interacts with a complementary contour on the implant head. It is known from US-A-5,312,254 and US-A-5,538,428 to introduce a connection element be-tween the cover and the implant, which connection ele-ment transmits the rotating screw-in movement. US-A-5,062,800 discloses an ampule in which the cover forms the connection element to the screwing-in tool. Some of these ampules are rather expensive, and the tool compo-nents are generally used only once. In addition, a re-latively large number of actions are also required when using these ampules, and in addition there is a need for external screwing-in tools. Finally, it is questio-nable whether the implants are gripped sufficiently re-liably by the screw covers or the connection elements.
In the second type, the implant arranged in the ampulehas to be gripped and screwed in using an external tool. The current invention relates to this type of ampule. EP-B-0 231 730 discloses a simple variant in which the implant is in a sleeve and the implant head protrudes above and closes off a sleeve end. The sleeve is fused in a glass ampule, which has constrictions and an internal spring. The implant head is supported against the spring and the sleeve is fixed inside the constrictions, one constriction at least partially closing off the base of the sleeve. Suitable external tools are used to grip the implant, but there are no means provided on the ampules which facilitate and safeguard the removal of the implant from the ampule and the transportation to the implantation location.
Ampules of this type with sterile conditions are also described in the monograph written by SCHROEDER/SUTTER/BUSER/KREKELER: Oral Implantology, Georg Thieme Verlag Stuttgart and New York, 2nd Edition, 1996, pp. 219-221. The capsule-shaped ampule has a removable cover and a partition close to the cover which extends perpendicular to the longitudinal axis. In this partition, there is an axial passage in which a bearing ring rests, in which bearing ring the head of the implant is situated, while the apical part of the implant projects into the ampule. A threaded, blind axial bore is situated in the implant head. In order to take hold of the implant, a lockable screwing-in tool is attached, the threaded mandrel of which is screwed into the threaded bore of the implant. Having been screwed onto the screwing-in tool, the implant is then removed from the ampule. The implant is then in-troduced into the bore in the bone, keys being attached to the screwing-in tool. Finally, the locking between the implant and the screwing-in tool has to be released again, so that the screwing-in tool can be unscrewed.
This procedure requires numerous operations, a multi-part instrumentarium and particular attention and skill on the part of the surgeon.
Object of the invention In view of the abovementic,ned drawbacks of the devices known hitherto for gripping implants by means of a ma-nipulation component, the object underlying the inven-tion is to perfect such devices. The aim here is tomake the connection between the implant and the manipu-lation component, when gripping the implant, quick, reliable and achievable without additional tools. At the same time, the subsequent release of the implant during the separation between manipulation component and implant must likewise be possible in a simple man-ner. In operations which require a high level of clean-liness or sterility, the particular conditions are to be maintained with the device to be provided. In parti-cular in the preparatory phase prior to the surgical intervention and during the intervention, it is neces-sary to ensure that the implants and components of thedevice used are always guided reliably and do not be-come detached in an uncontrolled manner.
Based on the application example selected, the aim is to develop the ampule further in such a manner as to facilitate considerably the contamination-free removal of the implant from the ampule using the attached screwing-in tool, the screwing in of the implant and the final separation between the screwing-in tool and the implant. It will be understood that the ampule to be proposed has to fulfill all the requirements placed on it in terms of sterility and ease of handling. More-over, it must be possible to produce the ampule in a cost-effective manner as a disposable item with the holding device already integrated. As an alternative to an ampule, the object can also be achieved in conjunc-tion with a container or a simple base from which the implant is to be transferred.
Essence of the invention The device for holding an :implant comprises an adapter sleeve and a manipulation component, the adapter sleeve being provided for the temporary connection between the implant and a manipulation component. One end of the adapter sleeve can be pushed onto a plug-in projection of the positioned implant in such a manner that it can be detached again; the tip of the manipulation compo-nent can be attached to the other end of the adapter sleeve in such a manner that it can be detached again.
The implant is taken hold of by attaching the manipula-tion component to the adapter sleeve, which is already connected to the implant.
The double plug connection between implant, adapter sleeve and manipulation component then allows the im-plant to be transferred from the prior position into a new position. In this way, the implant can be trans-ferred from one workstation to the next or removed from a storage room or a container and transferred to the envisaged site of use, for example the implantation position on the patient. It is also possible to trans-fer, for example, a screw implant to the prepared drilled hole in the bone and to screw the implant into this hole. The manipulation component is in this case designed as a screwing-in tool and the rotational move-ment of the screwing-in tool is transferred to the im-plant by the fact that in the plugged-together state a non-rotationally symmetrical contour which is present at the tip of the screwing-in tool engages with a com-plementary non-rotationally symmetrical contour arranged on the implant.
When the manipulation component is pulled off the im-plant, the plug connection between the implant and the manipulation component becomes detached, while the adapter sleeve remains attached to the tip of the mani-pulation component. A lower detachment force is needed to separate the plug connection between the adapter sleeve and the plug-in projection on the implant than to separate the more intensive plug connection between the adapter sleeve and the manipulation component. Du-ring the further procedure, the adapter sleeve can be separately pulled off the manipulation component with a suitable application of force.
In an advantageous embodiment, the adapter sleeve is on the plug-in projection of the implant, while the tip of the manipulation component can be plugged into the second plug-on end of the adapter sleeve. To stabilize the latching plug connections between the adapter sleeve and, on the one hand, the plug-in projection on the implant and, on the other hand, the tip of the ma-nipulation component, it is expedient to provide lat-ching contours on the adapter sleeve and on the manipu-lation component, which latching contours preferably extend radially.
Returning to the concrete example for the use of the invention in an ampule for the transportation and sto-rage of an implant, in particular a dental implant, the device is designed as follows.
The adapter sleeve is used for the connection between the implant head and the implantation tool - e.g. a screwing-in tool - during the removal of the implant from the ampule and the insertion of the implant into the bone using the manipulation component, which is de-signed as a tool. One end of the adapter sleeve is pushed onto the head of the implant, which is fixed in the ampule, in such a manner that it can be detached again and surrounds the implant head; the tip of the tool can be attached to the other end of the adapter sleeve in such a manner that it can be detached again.
The implant can be pulled out of the ampule as a double plug connection between implant, adapter sleeve and screwing-in tool and then transferred to and inserted in the drilled hole prepared in the bone. If the im-plant is a screw implant, and consequently a screwing-in tool is used for the implantation, the rotational movement of the tool is transmitted to the implant by the fact that, in the plugged-together state, the non-rotationally symmetrical contour which is present atthe tip of the screwing-in tool engages with the com-plementary non-rotationally symmetrical contour arranged on the implant head. For example, the implant ends at the top with an external polygon, and the screwing-in tool has a complementary internal polygon.
When the tool is pulled off the implant, the plug con-nection between the implart and the tool becomes de-tached, but the adapter sleeve remains hanging from the tip of the tool, since the plug connection which can be detached with a lesser application of force, i.e. that between the adapter sleeve and the plug-in projection on the implant, is separated more easily than the stronger plug connection, which is more difficult to detach, between the adapte:r sleeve and the tool.
In a preferred embodiment, the adapter sleeve surrounds the implant head and is situated - in a manner holding the implant in the ampule - in a seat of the ampule housing in a manner allowing it to be pulled out, i.e.
the adapter sleeve is already an integral component of the ampule delivered. After opening the housing, for example by taking off a cover, and removing a fixing pin, which is additionally present as an optional ex-tra, the tip of the tool c~n be connected to the second plug-on end of the adapter sleeve.

Figure 1 The complete ampule includes the housing 100, the implant 1 fixed therein, an insert sleeve 200, an adapter sleeve 300 and a fixing pin 400.
The implant 1 which is shown here by way of example and is known per se has a head 10 which widens conically upward, will serve as a plug-in projection and has an external polygon 12 which rises above its radially en-circling shoulder 11. The :root part 13, which adjoins the head 10 and is provided with an external screw thread 14, extends in the apical direction.
The hollow housing 100 comprises a tubular piece 110, which is preferably closed at the bottom, in which case it is advantageous in production engineering terms for the closure to be a bottom stopper 120. In the region of the upper end, the tubular piece 110 has a partition 130 which is perpendicular to the longitudinal axis and has a central, axially running through-bore 131. The housing 100 can be closed off from above by means of a push-on, U-shaped cover 140. The tubular piece 110 protrudes above the partition 130, thus forming a radially encircling collar 111. The cover 140 has a projection 141 which points downward, a flange 142 which runs outward from the projection 141, and an inner contact shoulder 143. The flange 142 of the attached cover 140 bears against the collar 111, and the projection 141 fits tightly against the inside of the collar 111, the end face 144 of which projection rests on the partition 130.
The through-bore 131 is surrounded by a reinforcement rib 132 which is coaxial with the collar 111. An insert sleeve 200 is inserted into the through-bore 131, the upper, outwardly facing flange 210 of which insert sleeve rests on the top of the reinforcement rib 132.
The insert sleeve 200 fits tightly into the through-bore 131 and preferably cc,nsists of the same material as the implant 1, in order to preclude any risk of con-CA 02232402 l998-03-l6 tamination to the implant 1 in the event of any contact between the two. For this purpose, the insert sleeve 200 penetrates through the partition 130, protrudes into the interior of the housing 100 and extends down-ward beyond the implant shoulder 11 of the fixedimplant 1.
Between the implant head 10 and the insert sleeve 200 there is the adapter sleeve 300, which was pushed onto the implant head 10 before pushing the implant 1, with the root part 13 at the front, through the insert sleeve 200. At its coronal end, the adapter sleeve 300 has a radial bead 310 which projects outward and is supported on the top of the flange 210 of the insert sleeve 200. Toward the apical end, the adapter sleeve 300 surrounds the implant shoulder 11 until the implant head 10 narrows, and ends approximately at the level of the insert sleeve 200. To increase the elasticity of the adapter sleeve 300, partial longitudinal slots 320 may begin below the bead 310.
A radial gap remains naturally between the adapter sleeve 300 and the external polygon 12 of the implant 1. As a precautionary measure, the sleeve part 410 of the fixing pin 400 is pushed into this gap. The bottom edge of the sleeve part 410 rests on the implant shoul-der 11. Above the sleeve part 410, the fixing pin 400 has a disk 420 of widened diameter, the underside 421 of which rests on the top of the adapter sleeve 300, while its top side 422 is subject to pressure from the inner contact shoulder 143 of the attached cover 140.
This ensures that the implant 1 suspended in the hou-sing 100 can in no way slip forward toward the cover 140, thus becoming detached from its holder. Above the disk 420, the fixing pin 400 has a grip piece 430, which can be used to take hold of the fixing pin 400 more easily when plugging it in or pulling it out.
The remaining space inside the cover 140 could advan-tageously be used to store further implantation parts, for example for a healing cap.
Figures 2A and 2B
Locking grooves 211 may be provided in the flange 210 of the insert sleeve 200, in order to achieve a stron-ger connection to the reinforcement rib 132, in parti-cular a safeguard against rotation. Lugs on the rein-forcement rib 132 engage in these locking grooves 211.
A raised latching edge 220, which in the plugged-in state engages beneath the bottom edge of the partition 130 in the region of the through-bore 131, is present on the outside of the insert sleeve 200, in the region of the apical end of the insert sleeve 200. The insert sleeve 200 is thus fixed firmly in the through-bore 131. The latching edge 220 could run around the entire circumference or could be formed over sections of the circumference.
Figures 3A and 3B
At the coronal end, the adapter sleeve 300 has the out-wardly projecting bead 310, while a latching contour 330 for engaging around the implant shoulder 11 is pre-sent on the inside at the apical end. In accordance with the implant head 10, which widens conically toward CA 02232402 l998-03-l6 the implant shoulder 11, the latching contour 330 ad-vantageously comprises a radial groove 331 and a ralsed fitting edge 334 which is situated further toward the apical end, runs around the circumference and in the region of which the clear :internal width of the adapter sleeve 300 is narrowed. In the direction of the bead 310, the radial groove 331 ends with a stepped posi-tioning shoulder 332, the plane of which lies perpendi-cular to the longitudinal axis of the adapter sleeve 300. A conical transition 333 extends from the radial groove 331 to the fitting edge 334.
When the adapter sleeve 300 has been pushed onto the implant head 10, the positioning shoulder 332 comes to lie on the implant shoulde:r 11 and the remaining part of the latching contour 330 of the adapter sleeve 300, i.e. the conical transitio:n 333 and the fitting edge 334, surround the implant :head 10 below the implant shoulder 11. To facilitate pushing the adapter sleeve 300 onto the implant head 10, the adapter sleeve 300 has an entry chamfer 335 at its opening, which chamfer is followed by the fitting edge 334. The latching con-tour 330 fixes the adapter sleeve 300 on the implant head 10, but a defined force allows it to be pulled off the implant head 10. The ability of the adapter sleeve 300 to spread apart in the apical region is assisted by longitudinal slots 320, which begin at the apical end and extend part way toward the bead 310.
Figure 4 The fixing pin 400, with its sleeve part 410, the disk 420 and the grip piece 430, is not absolutely neces-sary, but is provided for safety reasons in order to preclude an axial loosening of the implant 1 which is suspended in the ampule. The hollow sleeve part 410 can be plugged in between the external polygon 12 of the implant 1 and the adapter sleeve 300, so that the ex-ternal polygon 12 is received inside the sleeve part 410.
Figures 5A to 5C
The manipulation component 500 - in this example in the form of a screwing-in tool 500 - which is provided for taking hold of the implant 1 suspended in the ampule is of conventional nature with regard to its ratchet head 510, the shank 520 and the plug-on profile 550 present on the inside of the shank tip 530. In a complementary manner to the external polygon 12 of the implant 1 used here by way of example, the plug-on profile 550 is de-signed as an internal polygon.
The shank tip 530, on which a latching contour 540 is present, has a particular configuration on the outside.
The shank tip 530 is of reduced external diameter by comparison with the shank 520, so that an annular shoulder 521 is formed at the transition from the shank tip 530 to the shank 520. In front of the annular shoulder 521, and at a distance from the latter, there is a raised, radially encircling ramp 541 with a conical run-up 542 on the apical side of the ramp 541.
A notch 545, which runs perpendicular to the longitudi-nal axis of the screwing-in tool 500, is present be-tween the annular shoulder 521 and the ramp 541, so that the ramp 541 ends abruptly on the coronal side.
CA 02232402 l998-03-l6 Advantageously the depth of the notch 545 is such that its base lies below the surface of the rest of the shank tip 530.
If the implant 1 used is made of titanium, it is expe-dient if the insert sleeve 200 is also made of tita-nium. A variety of plastics can be recommended as mate-rials for the housing 100, the adapter sleeve 300 and the fixing pin 400.
Operating procedure The handling of the ampule with the use of the screwing-in tool 500 is described below, it being assumed that the complete ampule in accordance with Figure 1 has already been removed from the further packaging and that it contains an implant 1. The im-plant 1 is taken to be a dental implant and is to be inserted in a bore which has been prepared in the jaw bone.
Step 1 - Remove the cover 140 from the housing 100;
- This makes the fixing pin 400 accessible;
Step 2 - Pull out the fixing pin 400;
- This makes the implant head 10 accessible from above;
Step 3 - The shank tip 530 of the screwing-in tool 500 is plugged into the adapter sleeve 300 from above, it first being necessary to search for the form fit be-CA 02232402 l998-03-l6 tween the plug-on profile 550 and the external poly-gon 12;
- The adapter sleeve 300 slides over the shank tip 530 and is pushed over the conical run-up 542 of the ramp 541 as far as the annula:r shoulder 521;
- The plug connection between the screwing-in tool 500 and the adapter sleeve 300 is latched in;
- The plug-on profile 550 engages around the external polygon 12 of the implant head 10;
Step 4 - The screwing-in tool 500 with the attached adapter sleeve 300, from which the implant head 10 is sus-pended at the other end, is removed from the ampule, so that the implant 1 is pulled out of the ampule through the insert sleeve 200;
Step 5 - The implant 1, which has docked with the screwing-in tool 500, is moved toward the bore in the jaw bone and is inserted into the bore;
- The implant 1 is screwed into the bore by turning the screwing-in tool 500 manually or mechanically;
25 Step 6 - After the end of the screwing operation, the screwing-in tool 500 is pulled off the screwed-in implant 1;
- The holding force between the adapter sleeve 300 and the latching contour 540 on the shank tip 530 of the screwing-in tool 500 is greater than the holding CA 02232402 l998-03-l6 force between the inner latching contour 330 of the adapter sleeve 300 and the implant head 10;
- The fitting edge 334 of the adapter sleeve 300 passes over the implant shoulder 11, so that the adapter sleeve 300 is detached f:rom the implant head 10;
- By contrast, the adapter sleeve 300 remains coupled to the screwing-in tool 500;
Step 7 - Finally, the inserted implant 1 is treated further;
- The adapter sleeve 300 is removed manually from the shank tip 530 of the screwing-in tool 500;
- The screwing-in tool 500 is cleaned and is then available for use again.
Further design variants on the devices described above can be realized. Express mention is made here of:
- The manipulation components 500 initially considered are implantation tools, such as screwing-in and knocking-in instruments. These components also in-clude surgical instruments for taking hold of the implants 1 as well as transportation means which are used during the production and treatment of the implants 1.
- The implants 1 considered in the context of the pre-sent invention are screws, pins and nails used in bone surgery, including dental surgery. The invention also relates to osteosynthesis parts, including plates, for example those used in the maxillofacial area. Finally, the term "implants" used here should also be understood to include build-up parts, such as abutments and prosthetic suprastructures.
- The holding device can be used for any application -in particular for medical engineering products -where there is a need for targeted or controlled manipulation or positioning.
- The function of the plug-in projection 10 may also be assumed by protrusions Oll or recesses in implants, as well as by the heads of cylindrical implants 1.
- The latching contours 330,540 on the adapter sleeves 300 and/or on the manipu:lation components 500 may in each case be arranged on the inside and/or on the outside, depending on the form of the plug-in projec-tions 10. The decisive criterion is that in the plugged-together state, with the increasing applica-tion of force, the plug connection between the adap-ter sleeve 300 and the plug-in projection 10 on the implant 1 is detached fi:rst. Consequently, the adap-ter sleeve 300 remains hanging from the manipulation component 500 when the manipulation component 500 is pulled off the implant 1.
- The entraining function, which has hitherto been per-formed by the plug-on profile 550 of the manipulation component 500 and by the external polygon 12 on the implant head 10 being in mutual engagement, could also be achieved by entrainment contours being pre-sent, in addition to the latching contour 330, on the adapter sleeve 300 itself, preferably on the end side thereof.

Device for holding an implant, an osteosynthesis part, an a~~ociated build-up part or an in~trument Application area of the invention The invention relates to a device for holding an im-plant, an osteosynthesis part, an associated build-up part or an instrument by means of a manipulation compo-nent. Possible implants are screws, pins and nails used in bone surgery, and therefore also in dental surgery.
The osteosynthesis parts here also include plates, for example those used in the maxillofacial area. Build-up parts are understood to mean abutments and prosthetic suprastructures. For the sake of simplicity, all these parts - including the instruments to be held - are for the time being referred to only as implants. Manipula-tion components are implantation tools, transport means and instruments for holding.
The invention can be used in the production of im-plants, to prepare them prior to surgical interventions and during the actual intervention itself. The princi-pal application area of the invention is when the im-plants must not be taken hold of, at least directly, by the hands, for example because it is necessary to use a sterile procedure, and when it is important to hold the implants safely, but also to release them again quickly and without additional tools.
A concrete example of the use of the invention is an ampule for the transportation and storage of an im-plant, in particular a dental implant, which is inten-ded to be inserted - e.g. screwed - into a receiving bore which has been prepared in the bone. The receiving bore may be a threaded bore, or else the implant has a self-tapping thread. After opening, the implant can be removed from the ampule during the surgical interven-tion under sterile conditions using an attached tool, and can then be inserted into the receiving bore in the bone using this tool. Preferably, the ampule can be opened by removing a closure cover. In order to ensure that the procedure is sterile, it is usual to store the ampule in a secondary capsule until the start of the intervention.
Prior art Various manipulation components are known for handling implants, in which the implants are taken hold of in a form-fitting and/or force-fitting manner. This results in the difficulty that the implant can only be taken hold of reliably at high instrument and manual outlay.
At the same time, releasing the implant is more complex and, in addition, there is an increased risk of conta-mlnat lon .
Based on the concrete application example selected, the situation is as follows in the case of ampules, whilemaintaining sterile conditions. There are two fundamen-tal types of ampules. In a first type, the implant stored in the ampule is connected to the cover, which, directly or indirectly, at the same time functions as the screwing-in tool and is used at least to some ex-tent to screw in the implant. According to US-A-4,856,648, in its simplest form the cover has a projec-tion with a non-rotationally symmetrical engagement contour which interacts with a complementary contour on the implant head. It is known from US-A-5,312,254 and US-A-5,538,428 to introduce a connection element be-tween the cover and the implant, which connection ele-ment transmits the rotating screw-in movement. US-A-5,062,800 discloses an ampule in which the cover forms the connection element to the screwing-in tool. Some of these ampules are rather expensive, and the tool compo-nents are generally used only once. In addition, a re-latively large number of actions are also required when using these ampules, and in addition there is a need for external screwing-in tools. Finally, it is questio-nable whether the implants are gripped sufficiently re-liably by the screw covers or the connection elements.
In the second type, the implant arranged in the ampulehas to be gripped and screwed in using an external tool. The current invention relates to this type of ampule. EP-B-0 231 730 discloses a simple variant in which the implant is in a sleeve and the implant head protrudes above and closes off a sleeve end. The sleeve is fused in a glass ampule, which has constrictions and an internal spring. The implant head is supported against the spring and the sleeve is fixed inside the constrictions, one constriction at least partially closing off the base of the sleeve. Suitable external tools are used to grip the implant, but there are no means provided on the ampules which facilitate and safeguard the removal of the implant from the ampule and the transportation to the implantation location.
Ampules of this type with sterile conditions are also described in the monograph written by SCHROEDER/SUTTER/BUSER/KREKELER: Oral Implantology, Georg Thieme Verlag Stuttgart and New York, 2nd Edition, 1996, pp. 219-221. The capsule-shaped ampule has a removable cover and a partition close to the cover which extends perpendicular to the longitudinal axis. In this partition, there is an axial passage in which a bearing ring rests, in which bearing ring the head of the implant is situated, while the apical part of the implant projects into the ampule. A threaded, blind axial bore is situated in the implant head. In order to take hold of the implant, a lockable screwing-in tool is attached, the threaded mandrel of which is screwed into the threaded bore of the implant. Having been screwed onto the screwing-in tool, the implant is then removed from the ampule. The implant is then in-troduced into the bore in the bone, keys being attached to the screwing-in tool. Finally, the locking between the implant and the screwing-in tool has to be released again, so that the screwing-in tool can be unscrewed.
This procedure requires numerous operations, a multi-part instrumentarium and particular attention and skill on the part of the surgeon.
Object of the invention In view of the abovementic,ned drawbacks of the devices known hitherto for gripping implants by means of a ma-nipulation component, the object underlying the inven-tion is to perfect such devices. The aim here is tomake the connection between the implant and the manipu-lation component, when gripping the implant, quick, reliable and achievable without additional tools. At the same time, the subsequent release of the implant during the separation between manipulation component and implant must likewise be possible in a simple man-ner. In operations which require a high level of clean-liness or sterility, the particular conditions are to be maintained with the device to be provided. In parti-cular in the preparatory phase prior to the surgical intervention and during the intervention, it is neces-sary to ensure that the implants and components of thedevice used are always guided reliably and do not be-come detached in an uncontrolled manner.
Based on the application example selected, the aim is to develop the ampule further in such a manner as to facilitate considerably the contamination-free removal of the implant from the ampule using the attached screwing-in tool, the screwing in of the implant and the final separation between the screwing-in tool and the implant. It will be understood that the ampule to be proposed has to fulfill all the requirements placed on it in terms of sterility and ease of handling. More-over, it must be possible to produce the ampule in a cost-effective manner as a disposable item with the holding device already integrated. As an alternative to an ampule, the object can also be achieved in conjunc-tion with a container or a simple base from which the implant is to be transferred.
Essence of the invention The device for holding an :implant comprises an adapter sleeve and a manipulation component, the adapter sleeve being provided for the temporary connection between the implant and a manipulation component. One end of the adapter sleeve can be pushed onto a plug-in projection of the positioned implant in such a manner that it can be detached again; the tip of the manipulation compo-nent can be attached to the other end of the adapter sleeve in such a manner that it can be detached again.
The implant is taken hold of by attaching the manipula-tion component to the adapter sleeve, which is already connected to the implant.
The double plug connection between implant, adapter sleeve and manipulation component then allows the im-plant to be transferred from the prior position into a new position. In this way, the implant can be trans-ferred from one workstation to the next or removed from a storage room or a container and transferred to the envisaged site of use, for example the implantation position on the patient. It is also possible to trans-fer, for example, a screw implant to the prepared drilled hole in the bone and to screw the implant into this hole. The manipulation component is in this case designed as a screwing-in tool and the rotational move-ment of the screwing-in tool is transferred to the im-plant by the fact that in the plugged-together state a non-rotationally symmetrical contour which is present at the tip of the screwing-in tool engages with a com-plementary non-rotationally symmetrical contour arranged on the implant.
When the manipulation component is pulled off the im-plant, the plug connection between the implant and the manipulation component becomes detached, while the adapter sleeve remains attached to the tip of the mani-pulation component. A lower detachment force is needed to separate the plug connection between the adapter sleeve and the plug-in projection on the implant than to separate the more intensive plug connection between the adapter sleeve and the manipulation component. Du-ring the further procedure, the adapter sleeve can be separately pulled off the manipulation component with a suitable application of force.
In an advantageous embodiment, the adapter sleeve is on the plug-in projection of the implant, while the tip of the manipulation component can be plugged into the second plug-on end of the adapter sleeve. To stabilize the latching plug connections between the adapter sleeve and, on the one hand, the plug-in projection on the implant and, on the other hand, the tip of the ma-nipulation component, it is expedient to provide lat-ching contours on the adapter sleeve and on the manipu-lation component, which latching contours preferably extend radially.
Returning to the concrete example for the use of the invention in an ampule for the transportation and sto-rage of an implant, in particular a dental implant, the device is designed as follows.
The adapter sleeve is used for the connection between the implant head and the implantation tool - e.g. a screwing-in tool - during the removal of the implant from the ampule and the insertion of the implant into the bone using the manipulation component, which is de-signed as a tool. One end of the adapter sleeve is pushed onto the head of the implant, which is fixed in the ampule, in such a manner that it can be detached again and surrounds the implant head; the tip of the tool can be attached to the other end of the adapter sleeve in such a manner that it can be detached again.
The implant can be pulled out of the ampule as a double plug connection between implant, adapter sleeve and screwing-in tool and then transferred to and inserted in the drilled hole prepared in the bone. If the im-plant is a screw implant, and consequently a screwing-in tool is used for the implantation, the rotational movement of the tool is transmitted to the implant by the fact that, in the plugged-together state, the non-rotationally symmetrical contour which is present atthe tip of the screwing-in tool engages with the com-plementary non-rotationally symmetrical contour arranged on the implant head. For example, the implant ends at the top with an external polygon, and the screwing-in tool has a complementary internal polygon.
When the tool is pulled off the implant, the plug con-nection between the implart and the tool becomes de-tached, but the adapter sleeve remains hanging from the tip of the tool, since the plug connection which can be detached with a lesser application of force, i.e. that between the adapter sleeve and the plug-in projection on the implant, is separated more easily than the stronger plug connection, which is more difficult to detach, between the adapte:r sleeve and the tool.
In a preferred embodiment, the adapter sleeve surrounds the implant head and is situated - in a manner holding the implant in the ampule - in a seat of the ampule housing in a manner allowing it to be pulled out, i.e.
the adapter sleeve is already an integral component of the ampule delivered. After opening the housing, for example by taking off a cover, and removing a fixing pin, which is additionally present as an optional ex-tra, the tip of the tool c~n be connected to the second plug-on end of the adapter sleeve.

Figure 1 The complete ampule includes the housing 100, the implant 1 fixed therein, an insert sleeve 200, an adapter sleeve 300 and a fixing pin 400.
The implant 1 which is shown here by way of example and is known per se has a head 10 which widens conically upward, will serve as a plug-in projection and has an external polygon 12 which rises above its radially en-circling shoulder 11. The :root part 13, which adjoins the head 10 and is provided with an external screw thread 14, extends in the apical direction.
The hollow housing 100 comprises a tubular piece 110, which is preferably closed at the bottom, in which case it is advantageous in production engineering terms for the closure to be a bottom stopper 120. In the region of the upper end, the tubular piece 110 has a partition 130 which is perpendicular to the longitudinal axis and has a central, axially running through-bore 131. The housing 100 can be closed off from above by means of a push-on, U-shaped cover 140. The tubular piece 110 protrudes above the partition 130, thus forming a radially encircling collar 111. The cover 140 has a projection 141 which points downward, a flange 142 which runs outward from the projection 141, and an inner contact shoulder 143. The flange 142 of the attached cover 140 bears against the collar 111, and the projection 141 fits tightly against the inside of the collar 111, the end face 144 of which projection rests on the partition 130.
The through-bore 131 is surrounded by a reinforcement rib 132 which is coaxial with the collar 111. An insert sleeve 200 is inserted into the through-bore 131, the upper, outwardly facing flange 210 of which insert sleeve rests on the top of the reinforcement rib 132.
The insert sleeve 200 fits tightly into the through-bore 131 and preferably cc,nsists of the same material as the implant 1, in order to preclude any risk of con-CA 02232402 l998-03-l6 tamination to the implant 1 in the event of any contact between the two. For this purpose, the insert sleeve 200 penetrates through the partition 130, protrudes into the interior of the housing 100 and extends down-ward beyond the implant shoulder 11 of the fixedimplant 1.
Between the implant head 10 and the insert sleeve 200 there is the adapter sleeve 300, which was pushed onto the implant head 10 before pushing the implant 1, with the root part 13 at the front, through the insert sleeve 200. At its coronal end, the adapter sleeve 300 has a radial bead 310 which projects outward and is supported on the top of the flange 210 of the insert sleeve 200. Toward the apical end, the adapter sleeve 300 surrounds the implant shoulder 11 until the implant head 10 narrows, and ends approximately at the level of the insert sleeve 200. To increase the elasticity of the adapter sleeve 300, partial longitudinal slots 320 may begin below the bead 310.
A radial gap remains naturally between the adapter sleeve 300 and the external polygon 12 of the implant 1. As a precautionary measure, the sleeve part 410 of the fixing pin 400 is pushed into this gap. The bottom edge of the sleeve part 410 rests on the implant shoul-der 11. Above the sleeve part 410, the fixing pin 400 has a disk 420 of widened diameter, the underside 421 of which rests on the top of the adapter sleeve 300, while its top side 422 is subject to pressure from the inner contact shoulder 143 of the attached cover 140.
This ensures that the implant 1 suspended in the hou-sing 100 can in no way slip forward toward the cover 140, thus becoming detached from its holder. Above the disk 420, the fixing pin 400 has a grip piece 430, which can be used to take hold of the fixing pin 400 more easily when plugging it in or pulling it out.
The remaining space inside the cover 140 could advan-tageously be used to store further implantation parts, for example for a healing cap.
Figures 2A and 2B
Locking grooves 211 may be provided in the flange 210 of the insert sleeve 200, in order to achieve a stron-ger connection to the reinforcement rib 132, in parti-cular a safeguard against rotation. Lugs on the rein-forcement rib 132 engage in these locking grooves 211.
A raised latching edge 220, which in the plugged-in state engages beneath the bottom edge of the partition 130 in the region of the through-bore 131, is present on the outside of the insert sleeve 200, in the region of the apical end of the insert sleeve 200. The insert sleeve 200 is thus fixed firmly in the through-bore 131. The latching edge 220 could run around the entire circumference or could be formed over sections of the circumference.
Figures 3A and 3B
At the coronal end, the adapter sleeve 300 has the out-wardly projecting bead 310, while a latching contour 330 for engaging around the implant shoulder 11 is pre-sent on the inside at the apical end. In accordance with the implant head 10, which widens conically toward CA 02232402 l998-03-l6 the implant shoulder 11, the latching contour 330 ad-vantageously comprises a radial groove 331 and a ralsed fitting edge 334 which is situated further toward the apical end, runs around the circumference and in the region of which the clear :internal width of the adapter sleeve 300 is narrowed. In the direction of the bead 310, the radial groove 331 ends with a stepped posi-tioning shoulder 332, the plane of which lies perpendi-cular to the longitudinal axis of the adapter sleeve 300. A conical transition 333 extends from the radial groove 331 to the fitting edge 334.
When the adapter sleeve 300 has been pushed onto the implant head 10, the positioning shoulder 332 comes to lie on the implant shoulde:r 11 and the remaining part of the latching contour 330 of the adapter sleeve 300, i.e. the conical transitio:n 333 and the fitting edge 334, surround the implant :head 10 below the implant shoulder 11. To facilitate pushing the adapter sleeve 300 onto the implant head 10, the adapter sleeve 300 has an entry chamfer 335 at its opening, which chamfer is followed by the fitting edge 334. The latching con-tour 330 fixes the adapter sleeve 300 on the implant head 10, but a defined force allows it to be pulled off the implant head 10. The ability of the adapter sleeve 300 to spread apart in the apical region is assisted by longitudinal slots 320, which begin at the apical end and extend part way toward the bead 310.
Figure 4 The fixing pin 400, with its sleeve part 410, the disk 420 and the grip piece 430, is not absolutely neces-sary, but is provided for safety reasons in order to preclude an axial loosening of the implant 1 which is suspended in the ampule. The hollow sleeve part 410 can be plugged in between the external polygon 12 of the implant 1 and the adapter sleeve 300, so that the ex-ternal polygon 12 is received inside the sleeve part 410.
Figures 5A to 5C
The manipulation component 500 - in this example in the form of a screwing-in tool 500 - which is provided for taking hold of the implant 1 suspended in the ampule is of conventional nature with regard to its ratchet head 510, the shank 520 and the plug-on profile 550 present on the inside of the shank tip 530. In a complementary manner to the external polygon 12 of the implant 1 used here by way of example, the plug-on profile 550 is de-signed as an internal polygon.
The shank tip 530, on which a latching contour 540 is present, has a particular configuration on the outside.
The shank tip 530 is of reduced external diameter by comparison with the shank 520, so that an annular shoulder 521 is formed at the transition from the shank tip 530 to the shank 520. In front of the annular shoulder 521, and at a distance from the latter, there is a raised, radially encircling ramp 541 with a conical run-up 542 on the apical side of the ramp 541.
A notch 545, which runs perpendicular to the longitudi-nal axis of the screwing-in tool 500, is present be-tween the annular shoulder 521 and the ramp 541, so that the ramp 541 ends abruptly on the coronal side.
CA 02232402 l998-03-l6 Advantageously the depth of the notch 545 is such that its base lies below the surface of the rest of the shank tip 530.
If the implant 1 used is made of titanium, it is expe-dient if the insert sleeve 200 is also made of tita-nium. A variety of plastics can be recommended as mate-rials for the housing 100, the adapter sleeve 300 and the fixing pin 400.
Operating procedure The handling of the ampule with the use of the screwing-in tool 500 is described below, it being assumed that the complete ampule in accordance with Figure 1 has already been removed from the further packaging and that it contains an implant 1. The im-plant 1 is taken to be a dental implant and is to be inserted in a bore which has been prepared in the jaw bone.
Step 1 - Remove the cover 140 from the housing 100;
- This makes the fixing pin 400 accessible;
Step 2 - Pull out the fixing pin 400;
- This makes the implant head 10 accessible from above;
Step 3 - The shank tip 530 of the screwing-in tool 500 is plugged into the adapter sleeve 300 from above, it first being necessary to search for the form fit be-CA 02232402 l998-03-l6 tween the plug-on profile 550 and the external poly-gon 12;
- The adapter sleeve 300 slides over the shank tip 530 and is pushed over the conical run-up 542 of the ramp 541 as far as the annula:r shoulder 521;
- The plug connection between the screwing-in tool 500 and the adapter sleeve 300 is latched in;
- The plug-on profile 550 engages around the external polygon 12 of the implant head 10;
Step 4 - The screwing-in tool 500 with the attached adapter sleeve 300, from which the implant head 10 is sus-pended at the other end, is removed from the ampule, so that the implant 1 is pulled out of the ampule through the insert sleeve 200;
Step 5 - The implant 1, which has docked with the screwing-in tool 500, is moved toward the bore in the jaw bone and is inserted into the bore;
- The implant 1 is screwed into the bore by turning the screwing-in tool 500 manually or mechanically;
25 Step 6 - After the end of the screwing operation, the screwing-in tool 500 is pulled off the screwed-in implant 1;
- The holding force between the adapter sleeve 300 and the latching contour 540 on the shank tip 530 of the screwing-in tool 500 is greater than the holding CA 02232402 l998-03-l6 force between the inner latching contour 330 of the adapter sleeve 300 and the implant head 10;
- The fitting edge 334 of the adapter sleeve 300 passes over the implant shoulder 11, so that the adapter sleeve 300 is detached f:rom the implant head 10;
- By contrast, the adapter sleeve 300 remains coupled to the screwing-in tool 500;
Step 7 - Finally, the inserted implant 1 is treated further;
- The adapter sleeve 300 is removed manually from the shank tip 530 of the screwing-in tool 500;
- The screwing-in tool 500 is cleaned and is then available for use again.
Further design variants on the devices described above can be realized. Express mention is made here of:
- The manipulation components 500 initially considered are implantation tools, such as screwing-in and knocking-in instruments. These components also in-clude surgical instruments for taking hold of the implants 1 as well as transportation means which are used during the production and treatment of the implants 1.
- The implants 1 considered in the context of the pre-sent invention are screws, pins and nails used in bone surgery, including dental surgery. The invention also relates to osteosynthesis parts, including plates, for example those used in the maxillofacial area. Finally, the term "implants" used here should also be understood to include build-up parts, such as abutments and prosthetic suprastructures.
- The holding device can be used for any application -in particular for medical engineering products -where there is a need for targeted or controlled manipulation or positioning.
- The function of the plug-in projection 10 may also be assumed by protrusions Oll or recesses in implants, as well as by the heads of cylindrical implants 1.
- The latching contours 330,540 on the adapter sleeves 300 and/or on the manipu:lation components 500 may in each case be arranged on the inside and/or on the outside, depending on the form of the plug-in projec-tions 10. The decisive criterion is that in the plugged-together state, with the increasing applica-tion of force, the plug connection between the adap-ter sleeve 300 and the plug-in projection 10 on the implant 1 is detached fi:rst. Consequently, the adap-ter sleeve 300 remains hanging from the manipulation component 500 when the manipulation component 500 is pulled off the implant 1.
- The entraining function, which has hitherto been per-formed by the plug-on profile 550 of the manipulation component 500 and by the external polygon 12 on the implant head 10 being in mutual engagement, could also be achieved by entrainment contours being pre-sent, in addition to the latching contour 330, on the adapter sleeve 300 itself, preferably on the end side thereof.
