Abstract
The invention relates to a prosthesis shaft for receiving an amputation stump of an extremity, comprising connecting means for a distal prosthesis device (2), wherein the prosthesis shaft (1) comprises at least one shell (11, 12), which has an arched, open cross-section and the shell ends of which in the applied state overlap each other at least partially, at least one tensioning means (14, 15) being disposed on the shell (11, 12), said means acting in the circumferential direction and tensioning the shell ends relative to each other, and the shell (11, 12) being made of a dimensionally stable plastic having regions with varying elasticity.
Claims28
A prosthesis socket for receiving an amputation stump of an extremity, comprising:
- at least one shell with a curved, open cross section and ends which at least partially overlap each other in an applied state;
- at least one tensioning means arranged on the at least one shell, the at least one tensioning means being configured to act in a circumferential direction to tension the ends of the at least one shell relative to each other;
- and
- at least one connector associated with the at least one shell for connecting a distal prosthesis device,
- wherein the at least one shell is made from a dimensionally stable plastic with areas of different elasticity, and
- wherein an inner face of the at least one shell has a direction-dependent surface configuration that offers greater resistance to sliding counter to a direction of insertion of the amputation stump than sliding in the direction of insertion, wherein the direction of insertion is in a direction from a proximal edge of the at least one shell toward a distal edge of the at least one shell.
A prosthesis system, comprising:
- a prosthesis socket for receiving an amputation stump of an extremity, including:
- at least one shell with a curved, open cross section and ends which at least partially overlap each other in an applied state;
- at least one tensioning means arranged on the at least one shell, the at least one tensioning means being configured to act in a circumferential direction to tension the ends of the at least one shell relative to each other;
- and
- at least one connector associated with the at least one shell for connecting a distal prosthesis device,
- wherein the at least one shell is made from a dimensionally stable plastic with areas of different elasticity, and
- wherein an inner face of the at least one shell has a direction-dependent surface configuration that offers greater resistance to sliding counter to a direction of insertion of the amputation stump than sliding in the direction of insertion, wherein the direction of insertion is in a direction from a proximal edge of the at least one shell toward a distal edge of the at least one shell;
- and
- a prosthesis device secured to the at least one connector.
