Abstract:
1. An impact and torque-absorbing prosthetic shock module comprising: an inner support member; an outer support member, said inner and outer support members being coaxially supported relative to one another and capable of relative rotation and axial translation; a resilient element resisting axial displacement of the support members; a torque resisting cuff providing torsional resistance to relative rotational motion between said support members wherein said cuff has a generally tubular shape and is proximally attached to an outer surface of one of said support members and distally attached to an outer surface of the other of said support members; and an adapter configured to proximally attach said shock module to a stump-supporting socket or intermediate device, said adapter being secured to one of said inner support member and outer support member but remaining unsecured relative to said resilient element, wherein said adapter can be at least partly removed to allow replacement of the resilient element.
