Abstract
The invention relates to prostheses for amputated patients. The shaft of the prosthesis has an outer shell and a concentric inner shell. Both shells are provided with longitudinal slits which are staggered in relation to each other and extend essentially in an axial direction. The diameter of the shaft of the prosthesis can be adjusted by tightening elements. An adaptor is fixed in the shaft of the prosthesis in such a way that the height of the adapter can be adjusted. A conical bearing surface for the stump of the limb is provided on the upper side of the adapter, a holding element for fixing an artificial limb is provided on the lower side of the same, and a coupling is provided inside the adapter for detachably fixing the coupling pin of a commercially available silicone liner.
Claims23
A prosthesis comprising:
- a silicone liner having a coupling pin;
- a prosthesis shaft for being fitted to a limb stump and provided with longitudinal slits in a portion thereof, the prosthesis shaft being adjustable in diameter by tightening elements;
- and
- a holding element for connecting an artificial limb with the prosthesis shaft,
- wherein the prosthesis shaft has a concentric band circumferentially attached thereto, the concentric band having a cylindrical adapter height-adjustably installed therein,
- wherein the adapter includes a bearing surface at an upper end thereof for receiving the limb stump or the end of the silicone liner and a holding element at a lower end, and
- wherein the adapter includes in an interior portion a coupling for detachably securing of the coupling pin at the upper end and mechanics for detaching the coupling.
A prosthesis comprising:
- a prosthesis shaft for receiving a limb stump, the prosthesis shaft including an inner shell and an outer shell that has longitudinal slits provided therein for enabling a diameter adjustment of the prosthesis shaft about the limb stump;
- and
- an adapter being height adjustably and securely attached to the prosthesis shaft at an upper end of the adapter, the adapter having a holding element provided on a lower end for attachably receiving an artificial limb, and the adapter having a coupling for releasably securing a coupling pin, the coupling pin being connectable to the limb stump.
