Definitions
- the invention relates to a prosthesis system with a prosthesis, in particular a prosthesis of the lower or upper extremity, which has two prosthesis parts which are connected to one another via a prosthesis joint with an upper joint part and a lower joint part pivotably about a joint axis, and a cover element that has a gap between the at least partially covers both prosthesis parts or between a prosthesis part, in particular a proximal prosthesis part, and the lower part of the joint.
- the prosthesis is preferably a prosthesis of the lower or upper extremity which is arranged on a thigh stump or an upper arm stump of a patient.
- the prosthesis has a proximal prosthesis part which is fixed to the stump and a distal prosthesis part which is connected to the proximal prosthesis part via the prosthesis joint so that it can pivot about the joint axis.
- the distal prosthesis part replaces the patient's lower leg or forearm, in particular in combination with the lower joint part.
- the prosthetic joint is accordingly a prosthetic knee joint or a prosthetic elbow joint.
- Such prostheses usually have both - especially in the flexed state - a gap between the proximal prosthesis part and the distal prosthesis part or between the proximal prosthesis part and the lower joint part and - in any state - between the upper joint part and the lower joint part, which depending on the angle of the proximal Prosthesis part to the distal prosthesis part can be of different sizes. It is usually minimally large in a maximally extended position, i.e. with the leg or arm fully extended. As the flexion increases, the gap increases. This leads to the prosthesis joint being exposed to environmental influences, with the additional risk that an item of clothing covering the prosthesis will become trapped in the gap during an extension movement.
- the human knee in particular has a characteristic shape which should be imitated in order to achieve a prosthesis that is as inconspicuous as possible.
- DE 102016 103743 B3 shows prosthetic cosmetics with a plurality of hingedly connected clasp elements which are coupled to one another via a tension element.
- the prosthetic cosmetic is fixed with one end on the distal prosthetic component and the proximal prosthetic component of the prosthesis.
- the clasp elements partially cover the gap created between the proximal and the distal prosthesis component.
- DE 102012009757 A1 relates to a cladding for a prosthetic device, in particular a prosthetic leg, the cladding at least partially covering the joint device between a first prosthetic part and a second prosthetic part in the wasted state. There is still a gap.
- the cladding is structurally very complex and cannot simply be dismantled or assembled by a prosthesis user.
- the invention is based on the object of reducing disadvantages in the prior art.
- the invention solves the problem by means of a prosthesis system with the features of the main claim.
- Advantageous configurations and developments of the invention are disclosed in the subclaims, the description and the figures.
- the cover element is mounted pivotably about the pivot axis on the distal prosthesis part, a prosthetic cosmetic attached to the distal prosthesis part or the lower joint part, or the lower joint part of the prosthetic joint.
- the cover element it is also possible within the scope of the invention for the cover element to be arranged on the proximal prosthesis part or on a component of a prosthetic cosmetic that is attached to the proximal prosthesis part or the upper joint part or on the upper joint part.
- a prosthetic cosmetic is also understood to mean, in particular, a prosthetic protector or, for example, also a shape compensation element.
- the different Embodiments of a prosthetic cosmetic serve in particular to give the prosthesis a more physiological appearance and / or to protect the prosthesis components from environmental influences such as moisture or contamination.
- the cover element is preferably arranged on the physical joint axis of the prosthesis joint, in particular slipped onto it, clipped onto it or latched onto it.
- the physical hinge axis can be designed as a bolt, tenon or the like, on which or which the cover element is mounted.
- the cover element is arranged on the lower joint part of the prosthetic joint.
- the upper part of the joint is usually the component of the prosthetic joint on which the proximal prosthetic part is fixed.
- the cover element is arranged, for example, on the lower joint part, a component of the cosmetic prosthesis of the lower joint part.
- the distal prosthesis part it is also possible for the distal prosthesis part to be attached to the upper part of the joint.
- the prosthesis joint usually consists of an upper joint part, which is also referred to as the joint head, and a lower joint part, which is also referred to as the joint frame.
- the joint upper part and the joint lower part are pivotally connected to one another via a physical joint axis.
- This physical joint axis can be part of the joint upper part or joint lower part, or it can be designed as a separate component.
- the lower joint part has, for example, a fork-shaped frame with sockets in which the physical joint axis with the upper joint part arranged thereon is mounted.

- the cover element is coupled to the upper joint part in a form-fitting and / or force-fitting manner via at least one coupling element, that is to say, in particular, is fixed relative to it.
- the cover element follows the joint upper part through the coupling accordingly by pivoting about the pivot axis of the cover element. Since the upper joint part and the lower joint part are each connected to a prosthesis part, a pivoting movement of the prosthesis parts about the joint axis accordingly leads to a simultaneous pivoting movement of the cover element.
- the gap between the two prosthesis parts or the prosthesis part and the lower joint part which increases during a flexion movement, is at least partially covered by the cover element.
- the dimensions of the cover element determine the degree to which the cover element covers the gap. At the same time, of course, this depends on the angle between the prosthesis parts and the size of the gap, which is dependent on it.
- the distal prosthesis part is usually from an angle of 0 °, i.e. maximum extension, up to an angle of 120 ° to 160 °, in particular up to an angle of about 135 °, i.e. maximum flexion, relative to the proximal one Swiveling prosthesis part and vice versa.
- the cover element is preferably dimensioned such that it covers the gap at pivot angles from 0 ° to 45 °, preferably from 0 ° to 50 °, in particular from 0 ° to 90 °. This means that in the case of the leg prosthesis the cover element covers the gap ventrally and in the case of the arm prosthesis on the side opposite the elbow over the stated angle range.
- the cover element is part of a multi-part joint protection device which is attached to the prosthesis part, a component of the prosthetic cosmetic or the prosthesis joint and has a visor on which the cover element is pivotably mounted about the pivot axis.
- the joint protection device is preferably attached to the lower joint part of the prosthetic joint or to a component of the prosthetic cosmetic that is mounted thereon.

- the joint protection device also has a carrier, which is in particular a component of the cosmetic prosthesis to which the cover element and / or the visor is or are attached.
- the joint protection device is designed in at least three parts in this embodiment, namely with the carrier, the visor and the cover element.
- the cover element is pivotably mounted on the visor, for example, and the visor itself is attached to the carrier.
- the cover element and visor are pivotably mounted on the carrier in a correspondingly combined manner.
- the joint protection device is attached to the prosthesis part or the prosthesis joint by means of the carrier.
- the visor with the cover element arranged thereon, preferably has form and / or force-locking elements for fastening the visor to the carrier.
- the carrier preferably has connecting elements.
- the visor and the cover element can be formed from an elastic material, in particular a plastic, composite material or metal.
- the visor and the cover element are designed in the shape of a clasp.
- the visor On an inside of the visor facing the carrier, the visor then preferably has form-locking elements which are clipped or inserted into corresponding recesses in the carrier. For this purpose, the visor is widened against the restoring force of the elastic material and moved over the carrier. The form-locking elements are then introduced into the corresponding recesses by the restoring force and the visor is attached to the carrier. They may also have to be pressed manually into the corresponding recesses.
- the cover element, the visor or the carrier preferably has positive and non-positive locking elements via which the joint protection device is attached to the prosthetic part, the prosthetic cosmetic or the prosthetic joint.
- the visor preferably has form and / or frictional locking elements in order to attach the joint protection device to the prosthesis part, the prosthetic cosmetic or the prosthetic joint. If the joint protection device has a carrier, the form and / or force-locking elements are arranged on the carrier for connection to them.

- the carrier also has a clasp-like structure, namely such that it partially encompasses the prosthetic part, the prosthetic cosmetic or the prosthetic joint and has corresponding connection means for providing a snap connection.
- the carrier has, for example, recesses which are clamped onto corresponding projections.
- the carrier is preferably made of an elastic material so that it expands against a restoring force of the material can be. The carrier is then positioned over the corresponding elevations. The restoring force returns the wearer to its original shape and is then attached to the prosthesis part, the prosthetic cosmetic or the prosthetic joint.
- the elevations and the recesses are dimensioned, in particular asymmetrically, such that a rotation of the carrier relative to the component is not possible without deformation.
- the visor and / or the carrier can at least partially protrude beyond the gap between the two prosthesis parts.
- the gap is always covered to a certain extent by the visor and / or the wearer.
- the cover element projects beyond the gap in such a way that it is completely covered in the state of maximum extension, that is to say in the state in which the gap is smallest.
- Complete coverage is understood to mean, in particular, that the gap is covered ventrally in the case of a leg prosthesis and opposite the elbow in the case of an arm prosthesis.
- the mechanism of the joint protection device is preferably designed in such a way that the visor and the cover element jointly pivot up to a certain pivot angle, for example 75 °.
- the visor stops when pivoting further and only the cover element continues to pivot with it, in particular along with the proximal prosthesis part.
- the visor preferably remains stationary in such a way that its alignment relative to the lower joint part does not change in the event of a further pivoting, that is to say a further increase in the pivoting angle. It is possible, but not necessary, for a gap to be formed between the visor and the lower joint part when the visor has stopped.
- the cover element and visor completely cover the gap up to a pivoting angle of approximately 50 °.
- a pivoting angle is reached, a gap is formed between the visor and the lower joint part. This increases until the visor stops, for example at a pivot angle of 75 °. This makes it possible, for example, to provide sufficient coverage over a larger angular range without the joint protection device having to be dimensioned in such a way that the gap is completely covered regardless of the pivot angle. Investigations by the applicant have shown that a slight gap formation, as in the embodiment mentioned, can be justifiable.

- the visor is pivotably attached to this carrier. If the joint protection device does not have a carrier, the visor is pivotably mounted on the prosthetic part, the prosthetic cosmetic or the prosthetic joint. On the visor, in turn, the cover element is pivotably mounted or the visor and cover element share the physical axes, which is the subject of a preferred embodiment.
- pivot axes of the visor and the cover element coincide is preferably understood to mean that they are actually identical.
- this also includes, in particular, slight deviations of the axes from one another includes, which can be compensated for, for example, by the elasticity of the material and / or are caused by manufacturing tolerances.
- the visor and the cover element are additionally coupled to one another via at least one driver or the at least one driver is arranged on the cover element and can be brought into engagement with a corresponding element of the visor by pivoting the cover element relative to the visor.
- This embodiment in which both the visor and the cover element are pivotably mounted, ensures that the gap between the prosthesis parts can be covered over as large an angle range as possible, preferably over the entire flexion angle of the prosthesis joint.
- the driver is, for example, a snapper that can be attached and detached.
- the cover element has a projection which is slidably mounted in a corresponding groove of the visor element.
- the projection slides in the groove until it rests against a stop of the visor and comes into engagement with the latter.
- a more extensive pivoting movement of the cover element then leads to the visor being entrained and thus to a simultaneous pivoting movement of the visor.
- the gap it is possible, for example, for the gap to be completely covered by the cover element up to a pivot angle of 90 °. However, further pivoting of the cover element would lead to the gap being exposed again. However, this gap is not exposed by the driver and the visor coupled to the cover element, but the cover element and visor now jointly cover the gap so that for example, up to a pivoting angle of 120 ° or 135 °, the gap remains covered by the cover element and visor together.
- the pivot axis of the cover element and the joint axis of the prosthesis joint preferably coincide. This means that the axis about which the prosthesis parts are pivoted relative to one another is identical to the axis about which the cover element is pivoted. These are not the physical axes, but the imaginary axes of rotation. This ensures that no tension or deformation occurs when the cover element and the prosthesis parts are pivoted at the same time, as provided according to the invention.
- the hinge axis and the pivot axes of the visor and the cover element advantageously coincide. This ensures that the pivoting leads to little or no deformation or deformation at all.
- the coupling element is designed in one piece with the cover element, in particular in the form of a web, a clasp or a clip.

- the at least one coupling element is fixed directly to the upper part of the joint, for example in a clamping or locking manner.
- the at least one coupling element is not coupled directly to the upper joint part, but is clamped, for example, between the upper joint part and a prosthesis part, in particular the proximal prosthesis part.
- the at least one coupling element is coupled to the upper joint part in the sense of the invention.
- the at least one coupling element is preferably latched or clamped to the upper part of the joint.
- the at least one coupling element is designed as a clasp or clamp which at least partially engages around the upper part of the joint.
- the at least one coupling element is designed as a web which in particular has a projection which engages under the upper joint part or is clamped between the upper joint part and a prosthesis part, in particular the proximal prosthesis part.
- the proximal prosthesis part is fixed to the upper joint part, in particular via a pyramid adapter, and the coupling element is clamped in the form of a web between the upper joint part and the proximal prosthetic part.
- the invention relates to a joint protection device for such a prosthesis.

- FIG. 6 - a section of an embodiment of the prosthesis system
- FIG. 1 shows a prosthetic joint 4 of a prosthesis of a lower extremity.
- the prosthetic joint 4 is the prosthetic knee joint of a leg prosthesis.
- the prosthesis joint 4 has an upper joint part 6.
- a pyramid adapter 8 for connecting a proximal prosthesis part, for example a prosthesis shaft of the leg prosthesis, is arranged on the joint upper part 6, which is also referred to as the joint head.
- the prosthesis joint 4 also has a joint lower part 10.
- the lower joint part 10 and the upper joint part 6 can be pivoted relative to one another about a joint axis.
- the distal The prosthesis part for example a lower leg tube or a prosthetic foot, is attached to the lower joint part 10.
- the upper joint part 6 is shown pivoted relative to the distal prosthesis part and thus at the same time relative to the lower joint part 10. This is the state of flexion around the joint axis of about 90 °.
- the prosthesis part can have prosthetic cosmetics.
- the lower joint part 10 has two projections 12 that are not rotationally symmetrical about the joint axis, only one of the projections 12 being visible in the illustration on the left in FIG. If the distal prosthesis part has prosthetic cosmetic, it can use these projections 12 for a form-fitting hold on the prosthetic joint 4.
- the prosthesis joint 4 is shown with a maximally extended joint upper part 6.
- a carrier 14 of a joint protection device 16 is arranged on the prosthesis joint 4.
- the carrier 14 has structures 18 which are only shown in FIG. 3 and which correspond to the projections 12.
- the carrier 14 is detachably fixed on the prosthesis joint 4 and in particular on the joint lower part 10 via the projections 12 and corresponding structures 18. Due to the non-rotationally symmetrical shape of the projections 12 and the correspondingly correspondingly designed structures 18 of the carrier 14, the carrier 14 is fixed relative to the prosthesis joint 4 and the lower joint part 10 and cannot be pivoted relative to this.
- the carrier 14 has two connecting elements 20, only one of which can be seen in the central illustration of FIG. These correspond to the connection elements 22 of the joint protection device 16 shown in FIG Connection elements 22 are designed as form-fit elements corresponding to the connection elements 20 of the carrier 14. This realizes a releasable connection of the joint protection device to the carrier 14.
- the connection elements 22 are preferably at the same time the physical axes of the cover element and the visor.
- the prosthesis joint 4 is shown with the joint protection device 16 completely arranged thereon.
- the joint protection device 16 has the carrier 14, a visor 24 and a cover element 26.

- the section 30 has a curvature corresponding to the curvature of the upper joint part 6.
- the coupling element 28 Due to the geometry of the coupling element 28 shown, it not only rests on the upper joint part 6, but also engages with it in the manner of a snap mechanism. As a result, the cover element 26 is coupled to the joint upper part 6 via the coupling element 28.

If the prosthesis joint 4 performs a pivoting movement from the position shown in the middle and right-hand illustration to the position shown in the left-hand illustration, the cover element 26 executes a simultaneous pivoting movement about the pivot axis S due to the coupling via the coupling element 28 to the upper joint part 6 . As a result, the gap existing between the lower joint part 10 or a distal prosthesis component (not shown) and the proximal prosthesis part (not shown) and which increases in the course of the pivoting movement is at least partially, in particular completely, ventrally covered.
- connection elements 22 can be fixed to the carrier 14 via the connection elements 20, so that it cannot execute any movement relative to this.
- the cover element 26 and the visor 24 can also be designed to be pivotable about the connection elements 22. In a further embodiment, however, it is also possible for the visor 24 to be arranged on the carrier 14 such that it can pivot about a pivot axis via the connection elements 22 and the connecting elements 20.
- the pivot axis of the visor 24 and the pivot axis S of the cover element 26 coincide. Their physical axes are preferably also identical. At the same time, these pivot axes also coincide with the joint axis of the prosthesis joint 4.
- the cover element 26 preferably has a driver which is either permanently coupled to the visor 24 or can be brought into engagement with a corresponding element of the visor 24.
- the at least one driver makes it possible for the visor 24 to be carried along by the cover element 26 up to a certain degree of pivoting relative to the lower part of the joint.
- the at least one driver enables the cover element 26, preferably from a certain degree of pivoting relative to the lower joint part 10, to pivot the visor 24 relative to the lower joint part 10 or the distal Prosthesis component brings about. This is particularly useful if the prosthesis joint 4 allows pivoting, in which the resulting gap between the proximal prosthesis part and the lower joint part 10 can no longer be covered by the cover element 26 alone. The additional pivoting of the visor 24 then ensures additional coverage of the resulting gap and thus shielding of the prosthesis joint 4 from environmental influences.

- connection elements 22 are preferably at the same time the physical axes about which the cover element and visor can be pivoted.
- these connection elements 22 are constructed in two parts and are screwed together. Without loosening this screw connection, the cover element 26 and the visor 24 cannot be separated from one another in a non-destructive manner.

As already explained in FIG. 1, the cover element 26 has a coupling element 28. This has a distally extending section 30 and a contact surface 32 for the joint upper part 6 of a prosthesis joint 4.
- FIG. 3 shows the carrier 14 of a joint protection device 16. The carrier 14 from FIG. 3 corresponds to the embodiment from FIG.
- one of the two structures 18 can be seen, by means of which the carrier 14 can be fixed to a prosthetic cosmetic or to the prosthetic joint 4, in particular the lower joint part 10 of the prosthetic joint 4.
- the carrier 14 is fixed on the lower joint part 10 via the structures 18 and the corresponding projections 12.
- the carrier 14 is preferably made of an elastic plastic, so that the carrier 14 can be widened somewhat for placement on the prosthetic joint 4, in particular on the lower joint part 10, the restoring force of the material bringing the carrier 14 back to its original shape. This also makes it possible to clamp the carrier 14 in a particularly simple manner, for example on the prosthesis joint 4, in particular the joint lower part 10.
- FIG. 4 shows schematically how the visor 24 is attached to the carrier 14 or a component of the prosthetic cosmetic.
- the visor 24 and the cover element 26 are designed in the form of a clasp and are made of an elastic material, in particular a plastic.
- FIG. 5 shows a section through part of a prosthesis 3 of a prosthesis system 2 in a bent state, in which the gap 38 between the proximal prosthesis part 40 and the lower joint part 10 is shown.
- a distal prosthesis part 42 (not shown in the cutout), for example a lower leg tube or a foot, is attached to the lower joint part 10.

- the joint protection device 16 also has a visor 24.
- the joint protection device 16 is pivotably mounted via joints 36, which are at the same time connection elements 22, on a cosmetic prosthesis 46, which is fastened to the joint lower part 10 and in the present case is designed as a protector.
- the joints 36 are the physical axes, axle bolts or axle journals about which both the cover element 26 and the visor 24 are pivotably mounted on the prosthesis cosmetic 46, which is attached to the joint lower part 10.
- the proximal prosthesis part 40 is attached to the upper joint part 6, which is not visible, via an adapter 44.
- a distal prosthesis part 42 which in the present case is designed as a lower leg tube, is arranged on the lower joint part 10.
- FIG. 6 shows a bent, that is to say flexed, state of the prosthesis 3 of the prosthetic system 2.
- the cover element 26 and visor 24 are almost completely on top of one another.
- the visor 24 and the cover element 26 initially move along with it. This is due to the fact that the cover element 26 is connected to the upper joint part 6 via the coupling element 28, which is not visible, and the cover element 26 is coupled to the visor 24 via a driver, which is likewise not visible.
- the cover element 26 and visor 24 no longer cover the lower joint part 10 and the prosthetic cosmetic 46 ventrally, so that a gap is formed with increasing flexion.
- the mechanism of the joint protection device 16 is preferably designed in such a way that the visor 24 stops at a pivoting angle of approximately 75 °, that is, it is no longer pivoted with respect to the lower joint part 10 or the cosmetic prosthesis 46. From this pivot angle, only the cover element 26 is pivoted further, so that the visor 24 and the cover element 26 fold apart. This state is shown in FIG.
- the pivot angle is more than 90 ° here.
