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.
1-29. (canceled)
A prosthesis socket for receiving an amputation stump of an extremity, comprising:
The prosthesis socket as claimed in claim 1, wherein the at least one shell is made of several partial shells.
The prosthesis socket as claimed in claim 1, wherein the at least one shell comprises at least two shells arranged medially and laterally with respect to the amputation stump.
The prosthesis socket as claimed in claim 1, wherein the at least one shell is flexible in at least one proximal area of the at least one shell.
The prosthesis socket as claimed in claim 1, wherein the at least one shell is stiff in medial and lateral directions.
The prosthesis socket as claimed in claim 1, wherein the at least one shell is provided with a curvature configured to fit about a longitudinal extent of the amputation stump.
The prosthesis socket as claimed in claim 1, wherein the at least one shell is preshaped for adaptation to the amputation stump.
The prosthesis socket as claimed in claim 1, wherein the at least one connector is arranged in a proximal, relatively stiff area of the at least one shell.
The prosthesis socket as claimed in claim 1, wherein the at least one connector is arranged on the at least one shell in an area which corresponds in the applied state to a patient's greater trochanter.
The prosthesis socket as claimed in claim 1, wherein a center of rotation of the at least one connector is arranged on the at least one shell in an area which corresponds in the applied state to a patient's greater trochanter.
The prosthesis socket as claimed in claim 1, further comprising one or more fixing devices for orienting the distal prosthesis device relative to the at least one shell, wherein the at least one connector is configured for a pivotable bearing of the distal prosthesis device.
The prosthesis socket as claimed in claim 1, further comprising a cap secured as a distal closure piece on the at least one shell.
The prosthesis socket as claimed in claim 1, wherein the direction-dependent surface configuration of the inner face of the at least one shell is a nap velour which is oriented in a distal direction of the at least one shell.
The prosthesis socket as claimed in claim 1, wherein one or more inner faces of the at least one shell are coated with an adhesive layer.
The prosthesis socket as claimed in claim 1, wherein the at least one tensioning means is selected from a group consisting of velcro tapes, ski-boot fasteners, clips, and straps.
The prosthesis socket as claimed in claim 1, wherein the at least one tensioning means is positioned on a front portion of the prosthetic socket.
The prosthesis socket as claimed in claim 1, wherein the at least one tensioning means includes two tensioning means that are axially offset on the at least one shell.
The prosthesis socket as claimed in claim 1, wherein the at least one tensioning means is configured to act in a circular configuration.
The prosthesis socket as claimed in claim 1, wherein the at least one tensioning means is arranged on the at least one shell with two axially offset guides.
The prosthesis socket as claimed in claim 1, wherein the at least one shell forms a cone that widens in a proximal direction.
The prosthesis socket as claimed in claim 1, further comprising a frame secured either or both laterally and medially on the at least one connector.
A prosthesis system, comprising:
