ABSTRACT OF THE DISCLOSURE A voluntary closing prehensile prosthetic hand of laminated consturction having a natural reaching and positive gripping action, innate biofeedback characteristics, and greater gripping strength and utility. The thumb member is a cable actuated, rotatable member, which is spring biased to return to the open position. An internal hook, three co-operating gripping surfaces, and two manual locking devices provide a variety of closed positions for holding different sized objects. The overall design, which imitates the action of the human forefingers and thumb, results in a refined gripping action while increasing reaching and grasping capabilities.
