Abstract
In one embodiment, an impact and torque-absorbing module for a low profile lower limb prosthesis comprises two support members telescopingly engaged to permit axial and rotational motion therebetween. A resilient element resists axial displacement of the two support members, and a torque resisting cuff resists rotational displacement of the two support members. Precompression of the resilient element can reduce the size of the shock module making it more compact. The resilient element can also be replaced allowing adjustment of the shock absorption.
Claims12
A shock module comprising:
- an upper support member and a lower support member, said upper and lower support members being coaxially supported relative to one another and capable of relative rotation and axial translation;
- 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
- a resilient element resisting axial displacement of the support members;
- wherein said lower support member comprises a base at a lower end thereof and said base comprises at least a partially inclined attachment surface for attachment to a prosthetic foot member.
