Prosthetic functional component, upper limb, elbow unit, externally powered elbow unit


Prosthetic elbow unit designed to substitute for some of the functions of the normal elbow joint by controlled flexion/extension of the elbow. The axis of rotation may be monocentric or polycentric.
The activation of the motion is externally powered by power transmitted directly or via a linkage from another functional component. The control of movement is achieved by either a signal from a mechanical control site or myopotentials. It may be associated with a sequential, priority or microprocessor based programme. Feedback resulting from the vibration arising in an electrically driven device is assumed, but additional positional information may be provided by open or closed loop methods. The position of externally powered elbow units is normally maintained by the effect of the transmission, but an optional free swing mode may be incorporated.
The unit may include a humeral rotation unit to compensate for restriction of shoulder joint rotation in a prosthesis for a trans-humeral amputation.
