Description

Medical aid device

The present invention relates, inter alia, to a medical aid device, an arrangement and a use of this aid device and a method for its manufacture. In general, the invention relates to portable devices which are

can be attached to a person's body.

Medical aids are known in various designs in the state of the art. These are used, for example, in orthopedic applications to influence the range of motion of a body joint. Such

Devices can also be called orthoses.

Basically, a distinction can be made between static and dynamic orthoses. While the former completely fix the joint, the latter allow a certain degree of mobility. Dynamic orthoses are advantageous in order to enable the mobilization of the joint even in the event of injuries or other impairments.

which leads to better treatment results. Since the requirements for dynamic orthoses differ in different

Treatment cases often differ greatly, a targeted adaptation to the

The needs of the respective patient are advantageous. State-of-the-art

However, customizable orthoses are often complicated and require a lot of effort

manufacturable.

Prefabricated orthoses are also known, but due to the lack of individual adaptability to the needs of a patient, they often do not achieve the desired

provide treatment success.

These problems known in the prior art result in a conflict of objectives. The object of the present invention can therefore be seen as

to resolve this conflict of objectives.

In particular, a medical aid device is provided for this purpose, which consists of at least a holding device and a bending part. The holding device and the

Bending parts are connected to each other.

The holding device can establish the coupling or connection between the body part to be treated and the bending part or the bending beam. It is advantageous if the holding device enables the auxiliary device to be positioned essentially stationary on the said body part. Various solutions known in the prior art can be used for this, for example a stocking, a cuff or the like. It is also possible to design the holding device in several parts, for example in order to attach the auxiliary device to the body part on both sides of the joint to be treated, but to leave the area of the joint itself free. However, it is also conceivable to cover the area of the joint with a covering device. The covering device can, for example, be a

elastic glove.

The holding device can be made of or comprise an elastic material. Additionally or alternatively, the holding device can be made of or comprise a rigid material and/or a textile material. A tensioning device, for example a tensioning belt, can also be provided, with

which the holding device is attached to the body part. If necessary, the

holding device on the body or the body part to be treated

be investable.

The bent part is designed in particular as a bending beam and it comprises a plurality of segments, between which a particularly wedge-shaped recess is arranged. The recesses can also be designed in the shape of a circular arc, for example. The segments are connected to one another in particular via a connecting part. The wedge surfaces of the recess are thus formed in particular by corresponding side surfaces of adjacent segments. When a certain bend of the bent part is reached, these side surfaces can abut one another, thereby preventing or at least making it more difficult for the bent part to bend further. This is particularly the case when the recesses are on the concave side of the bent bent part. When the bent part assumes this position, this can also be referred to as the locking position. The flexibility is also particularly determined by the connecting part.

influenced.

The bent part can be straight or curved or have other suitable shapes. The segments and/or recesses can have different shapes. It is also possible to have several segments and/or recesses of one

bent part can be shaped differently.

The recesses can in particular run orthogonally to the longitudinal direction of the bending part or the bending beam, or they can run obliquely to its

longitudinal direction.

If a deflection occurs in such a way that the recesses are on the convex side of the bent part, no restriction of the deflection may be caused or the deflectability is only limited by the design of the connecting part

certainly.

In the present case, it was surprisingly found that this functionality can be profitably used to develop an improved medical aid device.

create.

The properties of the bending part are easily adjustable and can be adapted to the needs of the patient to be treated. For example, the size of the bending part can be changed depending on the joint to be treated. A bending part that is to be used for the treatment of a finger is usually smaller

than one for use on a knee.

In addition, the precise design of the segments and the wedge-shaped recesses in particular can be used to adapt to the specific conditions of the treatment situation. For example, by adjusting the opening angle of the wedge-shaped recesses, the angle position of the joint at which movement is restricted can be adjusted. As a rule, larger opening angles will allow a larger range of movement than smaller (i.e. sharper) opening angles. If necessary, an adjustment can be made additionally or alternatively by the precise design, for example the geometry or the

material of the connecting part.

Furthermore, the choice of material of the bent part can influence the properties of the

auxiliary device significantly.

In order to enable the properties of the bent part to be adapted as easily and flexibly as possible, it can be provided that the bent part or the bending beam is provided with

an additive manufacturing process, such as 3D printing.

It is particularly intended that several recesses on the bent part point in the same direction. Preferably, the direction is the one in which the angle of movement of the body joint to be treated points. Several recesses pointing in the same direction can optionally be arranged as a row of recesses.

be referred to.

Since many body joints can be moved in different directions, they usually have several angles of movement. Depending on the specific case, it may be necessary to influence several angles of movement with an auxiliary device. In this case, the auxiliary device can comprise several bent parts whose recesses point in different directions. However, it can also be provided that a bent part has recesses that point in different directions. If necessary, two or more rows of recesses can therefore be used.

that point in different directions.

The impact of the side surfaces of adjacent segments causes

Restriction of movement can therefore occur on one side, both sides or on more than one side.

It should also be noted that the connecting part can also have an influence on the mobility of the respective joint. In particular, the connecting part can provide a resistance or act as a resistance that counteracts the movement of the joint in certain directions. This resistance can act in particular in those directions that do not correspond to the orientation of the recesses. The resistance can be adjusted in particular by adjusting

material and/or geometry of the connecting part.

The bent part can be attached to the holding device in different ways. It can be provided that at least one of the ends of the bent part is loosely connected to the holding device, but both ends can also be rigidly connected to the holding device. If necessary, both ends can be rigidly connected to the holding device, while the middle area of the bending beam has no fixed connection to the holding device. If necessary, one end of the bent part can be rigidly connected to the holding device, while the other end is loosely or slidably connected to the holding device. If necessary, both ends can also be loosely or slidably connected to the holding device. If necessary, areas other than the ends of the bent part can also be

the holding device.

The connection between the holding device and the bent part can be made, for example, by means of adhesives, form-fitting connections or screw connections. The bent part can also be formed integrally with the holding device. If necessary, sleeves and/or

Loops must be provided into which the bent part is inserted.

The individual segments of the bent part can be connected in different ways, for example by a connecting part to which individual segments are attached. However, the bent part can also be formed in one piece, in which case the segments are formed integrally with the connecting part or with the entire bent part. The connecting part can be designed as a separate connecting part, for example as a connecting beam, but it is also possible for the holding device to act as a connecting part and for the segments to be attached directly to the

surface of the holding device.

There are no particular restrictions regarding the material of the bending beam. However, the use of plastic, especially thermoplastic, is advantageous due to its ease of processing, low weight and good flexibility. It can also be a combination

made of two or more materials.

If particularly long bent parts are required, for example when used in the area of the spine, it can be provided that a bent part is formed from several bent part sections that are connected to one another. This connection can be made, for example, by a plug connection or by another form-fitting connection. The connection can also be made by screw connections or by any other suitable connection.

between two parts.

The properties of the segments and/or the connecting part within a single bent part may also be different, especially if a bent part has a large length.

Variable properties can be, for example, the elasticity, the

7740

stiffness or the geometry of the segments and/or the connecting part.

This can enable locally adapted flexibility.

In order to extend the range of functions of the auxiliary device, an adjusting device can be provided. Using the adjusting device, the bent part can be moved to a defined

Positioned, pre-tensioned or actively moved.

The adjusting device can, for example, comprise an adjusting cable and/or an adjusting spring which run inside or along the bent part. By moving the adjusting cable

and/or adjusting spring, an active bending of the bent part can be achieved.

The adjusting device can also be used to cause an active movement of the bent part. The adjusting device can have an actuator to actively support the movement of the body joint. For example, a motor, a servo motor or a hydraulic, electric or pneumatic cylinder can be provided as an actuator. The adjusting cable(s) can be driven by the actuator. The adjusting cables can, for example, be designed as a Bowden cable.

be carried out.

The auxiliary device is in particular an orthosis, preferably a dynamic orthosis. With regard to the usage scenarios, it should be noted that the auxiliary device can basically be used on all body joints that have a restrictable angle of movement. The angle of movement can, for example, refer to an extension angle, a flexion angle, an abduction angle or an adduction angle of a joint, but also any other possible angle or rotation of a joint. The body part on which the respective joint is located can, for example, be a finger, a hand, a foot, a leg, a

upper body or lower body.

In one use of the present auxiliary device, a patient is treated with the auxiliary device. The patient can be a human being, but it is conceivable that the device can also be used on animals that have the appropriate

The patient does not necessarily have to undergo a

It can also be a person or a living being who needs the protection and/or support of a joint. This can be the case, for example, in

connection with sporting and/or professional activities.

Furthermore, a method for producing a bent part or a bending beam is provided, wherein the properties of the bent part or the bending beam are adapted to the requirements of the respective treatment situation. This adaptation can be preceded by an examination step, wherein this examination step is carried out in particular in a non-invasive manner.

If necessary, the holding device can also be adjusted.

In particular, a medical aid device, preferably an orthosis, is provided for influencing an angle of movement of a body joint, wherein the aid device comprises a holding device which can be fastened in the area of the body joint and

a bending beam connected to the holding device.

Preferably, the bending beam comprises several segments arranged in a row, and adjacent segments are connected by a particular

Fig. 1 to 3 show schematic views of an arrangement of an auxiliary device according to a first embodiment. The body joint 2 is in this

Embodiment of the wrist joint of a person. In Fig. 1, the body joint 2 is in a first, stretched, position. The

Auxiliary device is arranged on the body joint 2. For positioning, the

Stocking 12 formed holding device 4 in the area of the wrist joint

The stocking 12 in this embodiment is a stretchable

Textile material so that the device fits tightly to the body part to be treated.

A bending beam 5 is provided on the outer surface of the stocking 12, which in this embodiment has five segments 6 arranged one after the other in the longitudinal direction 10 of the bending beam 5. Wedge-shaped recesses 7 are provided between the segments 6. The recesses 7 are delimited by the side surfaces 3 of adjacent segments 6. The recesses 7 point away from the stocking 12. Therefore, the auxiliary device limits dorsal extension of the hand, while palmar flexion of the hand is not limited. In other directions of movement, the auxiliary device acts as a resistance. Depending on the elasticity of the bending beam 5, namely in particular depending on the elasticity of the connecting part 9, a resistance force is produced during abduction and adduction.

which counteracts the corresponding movements.

In this example, the bending beam 5 is made in one piece from a thermoplastic material. In particular, this bending beam 5 was manufactured using 3D printing in order to be able to adapt its geometry and bending properties to the conditions of the respective treatment situation. The bending beam 5 is made using

an adhesive to the holding device 4.

In Fig. 2, the body joint 2 is in a second, bent position. This position corresponds to the maximum that can be achieved by using the auxiliary device according to the invention - the bending beam 5 is therefore in the locked position. The angle of movement 1 here is approximately 60° compared to the straight alignment of the wrist, as shown in Fig. 1. Since a movement angle 1 (extension) of approximately 70° can be achieved with unrestricted mobility of the carpal joint, the auxiliary device according to this embodiment

This means that the mobility of the body joint 2 is restricted by approximately 10°. In this position — the locking position — the

arranged side surfaces 3 of the segments 6 to each other and thus limit a

further flexion of the body joint 2. In this embodiment, the

Segments 6 have a low elasticity, so that further movement would require a very high expenditure of force and is therefore practically impossible or only possible to a small extent. In other embodiments, however, the segments 6 can also be made of an elastic material or comprise this or have a reduced filling density ("infill"), so that further movement would require increased expenditure of force.

movement is possible.

In general, however, the flexibility is determined by the design of the connecting part 9. If the connecting part comprises an elastic material, mobility beyond the locking position can be enabled. However, if the connecting part 9 is only slightly elastic, movement beyond the

Moving beyond the locked position is only possible with great effort.

Fig. 3 shows the first embodiment in a schematic view from above. Here, the elongated shape of the bending beam 5 can be seen. The body joint 2

is in the first, stretched, position in this view.

Fig. 4 shows an arrangement of an auxiliary device according to a second embodiment in a side view. In comparison to the first embodiment, the recesses 7 point towards the stocking 12. Therefore, the range of motion during palmar flexion of the hand is restricted, while the dorsal extension of the wrist is not restricted. When moving in other directions, the auxiliary device exerts resistance, in particular through the effect of the

connecting part 9

Fig. 5 shows an arrangement of an auxiliary device according to a third embodiment in plan view. In comparison to the first embodiment, the stocking 12 extends to the index finger. In addition to a bending beam 5 with seven segments 6 in the area of the carpal joint, a further bending beam 5' with five segments 6 is provided. This further bending beam 5' spans another body joint 2°, namely the metacarpophalangeal joint of the index finger, the mobility of which in the dorsal direction is increased by the use of the bending beam 5'.

is restricted.

Fig. 6 shows an arrangement of an auxiliary device according to a fourth embodiment in plan view. This embodiment is similar to the third embodiment, but here no bending beam 5 is provided in the area of the carpal joint. The stocking 12 is arranged in the area of the metacarpal and index finger and the bending beam 5 with eight segments spans next to the

metacarpophalangeal joint and the middle joint of the index finger.

Fig. 7 shows a detailed view of a bending beam according to an embodiment in a casing 20. The casing 20 can be attached to the surface of the holding device 4, for example by sewing. The bending beam 5 is loosely inserted into the casing 20

so that it can be moved to a limited extent.

Furthermore, Fig. 7 shows the wedge angle 19, which is enclosed by the two side surfaces 3 of adjacent segments 6. In other embodiments, the wedge angles 19 can differ from one another and/or their orientation can be asymmetrical. The segments 6 are connected to one another by a connecting part 9, wherein the connecting part 9 forms a continuous web under the segments 6. In this embodiment, the connecting part 9 is formed in one piece with the segments 6. The dashed line is for illustration purposes only and is not intended to represent a physical separation between the connecting part 9 and the

segments 6.

Fig. 8 shows an arrangement of an auxiliary device according to a fifth embodiment in plan view. This embodiment is largely similar to the first embodiment, with the difference that the bending beam 5 is aligned at an angle. In other embodiments, the auxiliary device can also be used to limit abduction and/or adduction of the wrist. This would be possible, for example, if the bending beam 5 were rotated by 90° along its longitudinal extension direction 10 compared to the illustration in Fig. 8.

Furthermore, several bending beams 5 can be provided on one joint.

Fig. 9 shows an arrangement of an auxiliary device according to a sixth

Example of design in plan view. This example is largely similar to the

first embodiment, with the difference that the bending beam 5 is arranged laterally on the holding device 4. In other embodiments, the bending beam 5 can also be arranged on the palmar side of the wrist or generally on the

ventral side of a joint.

Fig. 10 shows a schematic view of a bending beam 5 according to an embodiment in a first bending position and Fig. 11 shows a view of the bending beam 5 according to the embodiment of Fig. 10 in a second bending position. These two views illustrate the behavior of the bending beam 5,

when it is placed in different bending positions.

In the first bending position shown in Fig. 10, the bending beam 5 essentially does not restrict movement. Here, the side of the bending beam 5 on which the recesses 7 are arranged has a convex curvature. The

Side surfaces 3 of adjacent segments 6 do not abut each other.

In comparison, in Fig. 11, the side of the bending beam 5 on which the recesses 7 are arranged has a concave curvature. The side surfaces 3 of adjacent segments 6 abut one another, so that compression of the segments or other deformation of the material of the segments 6 or expansion of the material of the connecting part 9 would have to be brought about in order to enable further curvature of the bending beam 5. Thus, when the bending beam 5 is bent in this direction, movement is restricted. The bending beam 5

is therefore in the locked position here.

Fig. 12 shows an arrangement of an auxiliary device according to a seventh embodiment in a side view. This embodiment is largely similar to the first embodiment, with the difference that the bending beam 5 has recesses 7 on two opposite sides. The recesses 7 point in the dorsal and palmar direction. This enables a restriction of movement of the body joint 2, namely during extension and

during bending. The connecting part 9 runs in the central area of the bending beam 5,

The dashed lines are for illustration purposes only and do not represent a physical

Separation of segments 6 and connecting part 9.

Fig. 13 shows an arrangement of an auxiliary device according to an eighth embodiment in a side view. This embodiment is largely similar to the first embodiment, with the difference that the bending beam 5 has recesses 7 on three sides. The recesses 7 point in the dorsal direction as well as in the lateral and medial direction. This not only enables a restriction of the dorsal flexion of the carpal joint, but also a

Movement in lateral and medial directions.

Fig. 14 shows a bending beam 5 according to an embodiment in a detailed view. The bending beam 5 is formed from two bending beam sections 8, which are connected to one another via a form-fitting connection. For this purpose, a form-fitting extension 24 is provided on one bending beam section 8 and a corresponding form-fitting recess 25 is provided on the other bending beam section 8. In this way, particularly long bending beams 5 can be provided, for example for use in a

extensive area of the spine.

Fig. 15 shows an arrangement of an auxiliary device according to a ninth embodiment in a side view. This embodiment is largely similar to the seventh embodiment, with the difference that a resistance element 26 is arranged on the upper side of the bending beam 5. The resistance element 26 is made of an elastomer material in this embodiment and generates a passive resistance during the parlmar flexure of the

wrist joint.

Fig. 16 shows an arrangement of an auxiliary device according to a tenth embodiment in a side view. This embodiment is largely similar to the ninth embodiment, with the difference that the resistance element 26 is arranged on the underside of the bending beam 5. Here too, the resistance element 26 generates a resistance during a movement of the

carpal joint in a dorsal direction.

The resistance element 26 can be connected to all segments 6 or only to selected segments 6. For example, the resistance element 26 can only be connected to the two segments 6 that are at the ends 15 of the bending beam 5

lay.

Fig. 17 shows an arrangement of an auxiliary device according to an eleventh embodiment in a side view. In comparison to the first embodiment, the auxiliary device according to this embodiment additionally comprises an adjusting device 13 which can be used to exert an axially directed force on the bending beam 5. This makes it possible in particular to support a movement of the carpal joint in the dorsal direction or to carry this out. The adjusting device 13 in this embodiment is an adjusting element 14 which is designed as a cable and is connected to the bending beam 5. Advantageously, the segments 6 block further deflection of the bending beam 5 in this direction when the side surfaces 3 abut against one another, which increases the safety of use in

Connection to a motorized actuator 13 or an actuator is possible.

Fig. 18 shows an arrangement of an auxiliary device according to a twelfth embodiment in a side view. This embodiment is largely identical to the eleventh embodiment, with the difference that the recesses 7 point in the palmar direction. The adjusting device 13 can therefore be used to support the movement of the carpal joint in the palmar direction or to

to carry out.

Fig. 19 shows an arrangement of an auxiliary device according to a thirteenth embodiment in a side view. The structure of the auxiliary device corresponds to the seventh embodiment, in which the actuating device 13 has two actuating elements 14 in the form of cables. As in the eleventh and twelfth embodiments, the actuating elements 14 can also be used here to support or carry out the movement of the

body joint 2.

Fig. 20 shows a bending beam 5 according to an embodiment in a detailed view. Here, the individual segments 6, the wedge-shaped recesses 7 and the

connecting part 9 formed integrally with the segments 6 is shown.

Fig. 21 shows an arrangement of an auxiliary device according to a fourteenth embodiment in plan view. The structure of the auxiliary device corresponds to the eighth embodiment, which is however supplemented by two actuating devices 13 in the form of actuating elements 14. The function of the actuating devices 13 has already been described in

context with other embodiments.

Fig. 22 shows a bending beam 5 according to an embodiment in a detailed view. In comparison to the bending beam 5 from Fig. 20, the recesses 7 are designed with notches 11 at their base. This enables an improvement in the mobility

of the bending beam 5 until the locking position is reached.

Fig. 23 shows an arrangement of an auxiliary device according to a fifteenth embodiment in a side view. The bending beam 5 is held at its two ends 15 in sleeves 16, which are arranged on the holding device 4. The bending beam 5 is held loosely in the sleeves 16, so that it can be moved to a limited extent.

is.

Fig. 24 shows an arrangement of an auxiliary device according to a sixteenth embodiment in a side view. This arrangement corresponds essentially to the fifteenth embodiment, with the difference that the bending beam 5 is also attached to the holding device in its central region 17, namely with a holding loop 18.

Fig. 25 shows an arrangement of an auxiliary device according to a seventeenth embodiment in a side view. Here, the bending beam 5 is supported by a casing 20

attached to the holding device 4.

Fig. 26 shows an arrangement of an auxiliary device according to an eighteenth

Embodiment in plan view. The holding device 4 or the stocking 12 is here

formed in two parts. In addition, the connection between the bending beam 5 and the holding device 4 is made by means of screw connections. Specifically, one end 15 of the bending beam 5 is rigidly connected to the holding device 4 via a fixed fastening 21, while the other end 15' of the bending beam 5 is connected to the holding device 4 via a movable fastening 23. The holding device 4 has
