Prosthesis socket and system comprising a prosthesis socket and prosthesis device

摘要

A prosthesis socket for receiving an amputation stump has at least one shell which has an arched, open cross-section, where the shell ends in the applied state overlap each other at least partially. At least one tensioning means is disposed on the shell to act in a circumferential direction for tensioning the shell ends relative to each other. The shell is being made of a dimensionally stable plastic having regions with varying elasticity. The proximal end of the socket is relatively more flexible. The inner surface of the socket includes a direction dependent surface to aid in holding the amputation stump. A connector for the distal prosthesis is preferentially positioned adjacent the patient's greater trochanter and is configured for pivotable bearing of the prosthesis with fixing devices to secure the orientation of the prosthesis relative to the socket.

1. A prosthesis socket for receiving an amputation stump of an extremity, comprising:
at least one shell which has a curved, open cross section and of which shell ends, in the applied state, at least partially overlap each other; at least one tensioning means arranged on the at least one shell, said at least one tensioning means is configured to act in a circumferential direction to tension the shell ends relative to each other; and at least one connector associated with said at least one shell for connecting a distal prosthesis device, wherein the at least one connector is configured as a pivotable bearing of the distal prosthesis device relative to said at least one shell and is configured to be arranged in an area which corresponds to a patient's greater trochanter; and at least one fixing device for adjustably orienting the distal prosthesis device relative to the at least one shell about a center of rotation of the at least one connector, wherein the at least one shell is made from a dimensionally stable plastic with areas of different elasticity with at least a portion of a proximal area of said at least one shell being relatively more flexible than other areas of said of said at least one shell.
