ABSTRACT:
The present invention is a prosthetic prehensor with two members extending in the same direction. One of the members rotates about a parallel axis removed from the first member until it contacts the first member. In the preferred embodiment, the two members are curved plates, one simulating a thumb and the other being wider and simulating a palm. The thumb plate rotates around a base plate which is coupled to the end of an arm. The thumb plate can contact the palm plate in either of two directions. This allows two types of gripping for fine objects and larger objects. The use of plates that are curved allows for a more aesthetic design than metal hooks.
