The invention relates to a prosthesis shaft for receiving an amputation stump of an extremity, comprising connecting means for a distal prosthesis device (), wherein the prosthesis shaft () comprises at least one shell (), 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 () being disposed on the shell (), said means acting in the circumferential direction and tensioning the shell ends relative to each other, and the shell () being made of a dimensionally stable plastic having regions with varying elasticity.

Prosthesis socket and system comprising a prosthesis socket and prosthesis device

The invention relates to an orthopedic interface () comprising a planar 3D textile () having a top () and a bottom (), which are held at a distance from each other by supporting threads () and are connected to each other, wherein the bottom () of the spaced knitted fabric () is configured for resting on the skin of an interface user. The side of the bottom () facing the skin is provided with an adhesive coating () at least in some regions.

Orthopedic interface

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.

The invention relates to an orthopaedic aid, in particular to a prosthesis () or orthosis comprising an orthopaedic fluid damper () with a displacement chamber () formed in a housing (), with a piston () mounted in the displacement chamber (), with a fluid reservoir for a fluid (), with a return flow conduit () connecting the displacement chamber () to the fluid reservoir, with a valve () that can adopt an open position and a closed position, in which it at least partially closes the return flow conduit (), and with a joint () that has a first branch () and a second branch (), wherein the first branch () is connected to the housing () and the second branch () is connected to the piston (). A device () is also provided for detecting a joint force (FB) acting on the joint, which device () is designed to bring the valve () to the closed position when the joint force (FB) exceeds a predefined threshold value. The invention also relates to a method for control of the aid and a fluid damper () fitted therein.
