PROSTHETIC LIMB AND ALIGNMENT ADAPTER

摘要

A prosthetic limb and alignment adapter (16) includes an elongated straight, flat bar (10) that elastically flexes in fore and aft directions while being resistant to flexion in the lateral directions. A separate adjustable prosthetic link (14) is fastened to each end of the straight, flat, flexible bar. Each prosthetic link includes a two-component, male/female adapter (26) in which a socket (44) having an integral bracket (18) is affixed to an end portion of the flat bar so the axis of the socket is aligned generally with the axis of the flat, flexible bar. A cooperating angular adjustment component of the link comprises a frustopyramidal, four-sided boss (32) divergingly projecting from a spherically convex base which slidably engages a correspondingly concave surface of the annular socket surrounding the boss. Two pairs of set screws (34) set 90 degrees apart in the angular socket are tightened against the sides of the frustopyramidal boss to enable its adjustment within separate swing angles in two mutually orthogonal planes defining fore and aft positioning and lateral-medial positioning of the component parts at opposite ends of the long flat flexible bar.
