Abstract
This invention relates to an improved construction and arrangement for a hand prosthesis wherein cooperating finger-like and thumb-like units are adapted to be yieldably biased towards a closed condition and are capable of being opened simply by pressing the prosthesis against an external object for reception of an item to be held. In operation one or both of the finger and/or thumb-like units are adapted to conform to the general profile of the contacted surfaces of the item to be grasped. Further a normally inoperative supplemental gripping force generating means is provided which is capable, when actuated, of applying a large separate additional gripping force over and above that which is normally applied by the said yieldable biasing action. Also one of said units is adapted to be selectively positioned in at least two different fixed positions relative to the other unit in order to make possible the gripping of different ranges of sizes of items to be held.
