Abstract:
1. A device configured for connecting a stump socket to a prosthetic foot, comprising: an upper rotatable member having an outer surface and a first longitudinal axis; a lower rotatable member having an outer surface and a second longitudinal axis coincident with the first longitudinal axis, the upper and lower rotatable members being rotatable with respect to one another about their longitudinal axes, and translatable with respect to one another along their longitudinal axes; a resilient member disposed between the upper and lower rotatable members for resisting relative axial motion of the upper and lower rotatable members, and absorbing shocks that occur as a result of such relative axial motion; and a tubular cuff secured at an upper end thereof to the outer surface of the upper rotatable member, and secured at a lower end thereof to the outer surface of the lower rotatable member; wherein the cuff resists relative rotation of the upper and lower rotatable members; and the maximum relative axial displacement of the upper and lower rotatable members is about one inch.
