Interim prosthesis for amputation stump uses thermoplastics heat-deformable shaft with shaft adapter and pull-cable between shafts ends for releasable arrest.

摘要

The distal connection (31) is cylindrical having pins, plugs or fluting on its outside surface and when enclosed by the shaft, the pins etc engage the shaft material, notably thermoplastics, so the shaft deforms under heat. The shaft adapter (32) is screwed to the distal connection and the interposed cam adapter of the shaft so the positive shape of the shaft adapter fits into the negative shape of the adapter cam. A cable (7) runs through the shaft adapter (32) and is joined at one end to the distal end of the liner and joined at the far end to a handle, the cable ends being releasably and arrestably joined to one another.
