TODAY’S PATENT – PROSTHETIC FINGER JOINT

The PROSTHETIC FINGER JOINT was invented by Peter S. Walker (Ridgewood, NJ) on 18th of March 1980, bearing the patent number US4193139A.

This invention relates generally to a prosthetic joint and, more particularly, concerns a hinge type prosthetic joint for replacement of a natural joint in the human body especially when relative movement of the components of the joint is generally in one plane.

The prosthetic joint is made up of three basic components. The first component is adapted to be associated with the first bone and is constructed as such that it may pivot. A second component has a terminal portion at one end facing towards the bearing surface of the first component and has rigid walls defining an open-ended socket. The third component is in the open-ended socket with its wall embracing the same so that the mating nearing surfaces cooperate to carry the loading forces of the joint in use.
