The invention relates to a prosthesis coupling. State of the art
The document WO 2007/076 795 A1 discloses a coupling for prostheses, in particular for prosthetic gripping devices, arm prostheses or hand prostheses. This prosthetic coupling has the disadvantages that it is relatively heavy, that it is difficult to operate, that it is prone to failure, and that it is expensive.
The document US 2013/0046 395 A1 discloses a hand prosthesis with a coupling part. This prosthesis coupling has the disadvantage that replacement of the prosthesis is relatively complex.
Presentation of the invention
The object of the invention is to propose a prosthesis coupling, which is easy to use, and which allows a simple exchange of prostheses.
This object is achieved with a prosthesis clutch comprising the features of claim 1. The dependent claims 2 to 15 relate to further advantageous embodiments.
The object is achieved in particular with a prosthetic coupling comprising a coupling part, a locking device, an adapter for fastening a prosthesis and a bottom part, wherein the coupling part has a recess, wherein the recess extends from an inlet opening in the direction of a longitudinal axis and a has cylindrical inner wall, wherein at the inlet opening opposite end of the recess, the bottom part is arranged, wherein the bottom part has a protruding into the recess tooth contour, wherein the adapter has a cylindrical outer surface and a first end face, and wherein the inner wall of the coupling part and the Outer surface of the adapter are configured mutually adapted so that the adapter via the inlet opening in the direction of the longitudinal axis is inserted into the recess, and wherein the adapter rotates on the inner wall in the circumferential direction to the longitudinal axis bar, wherein the adapter has on the first end face a toothing, which is aligned to the tooth contour, wherein the tooth contour and the toothing are configured adapted to each other so that the toothing can engage in the tooth contour when the adapter with the toothing on the toothing contour is applied, wherein the locking device is designed such that it has two positions, a first position in which the inserted into the recess adapter is displaceable both in the direction of the longitudinal axis and in the circumferential direction with respect to the coupling part, and a second position at which engages the toothing of the adapter in the toothing contour, and in which the adapter with respect to the coupling part in the direction of the longitudinal axis is not displaced.
The inventive prosthesis coupling comprises an adapter to which differently shaped prostheses can be fastened. The prosthesis coupling according to the invention has the advantage that the adapter can be inserted into the coupling part in a simple manner and that the adapter and the coupling part can be firmly connected to one another or also released again in a simple manner. The coupling part and the adapter each have a toothing, which engage with each other. This toothing has the advantage that the adapter can be easily rotated or aligned during mounting before the adapter is firmly connected to the coupling part. The adapter can therefore be easily aligned in the coupling part, so that the prosthesis, in particular a prosthetic hand, can be aligned according to the ergonomic requirements for performing a specific activity.
The toothing has in the circumferential direction successively preferably at least 6 and a maximum of 50 evenly spaced teeth. Thus, the minimum angle of rotation between the adapter and coupling part, for example, with a toothing of 50 teeth an angle of 7.2 °, and with a toothing of 6 teeth an angle of 60 °. The minimum possible angle of rotation between the adapter and the coupling part is thus determined by the number of teeth of the toothing. Further advantageous teeth are, for example, a toothing with 24 teething, which results in a minimum twist angle of 15 °, or a toothing with 12 teeth, which results in a minimum twist angle of 30 °.
The toothing is advantageously designed as a circular toothing, which has the advantage that the adapter is arranged particularly easily rotatable in the coupling part before attaching. A prosthesis is advantageously, depending on the activity to be performed, individually aligned. The inventive prosthesis coupling allows a user to insert a prosthesis in a first orientation in the coupling part, then try out the position of the prosthesis, and if necessary still rotate the prosthesis to align the prosthesis ergonomically advantageous according to the activity to be performed. The smooth turning allows a quick and comfortable adjustment of the alignment of the prosthesis, before it is firmly connected to the coupling part.
The inventive prosthesis clutch comprises a few parts, and is therefore reliable and easy in terms of operation, wear and maintenance. The prosthetic coupling is also relatively easily configured, can be used with a variety of different prostheses, and makes it easy to align a prosthesis according to the respective requirements.
In a particularly advantageous embodiment, the inventive prosthesis clutch comprises a ball detent mechanism for releasably locking the coupling part with the adapter. Such a ball detent mechanism allows a particularly simple and reliable actuation of the prosthetic coupling.

Fig. 3 shows an adapter 4 with a cylindrically extending outer surface 4a, which has a circumferential recess 4d. The adapter 4 also has holes 4e. A prosthesis part 6, of which only a portion of a fixing rod and the section 6b are shown, is fixedly connected to the adapter 4 by means of screws 6a. The adapter 4 has a first end face 4b, on which a toothing 4c is arranged. The adapter 4 has an overall height H.
