Abstract: An enhanced-functionality prosthetic limb is disclosed, comprising a prosthetic hand or gripping device, and forearm, which may be body-powered or motor-powered, targeted primarily for pediatric use, attachable to the arm stump of a below-elbow, or above-elbow, with the inclusion of a prosthetic elbow, amputee individual, with incorporation of one or more of the following features: expandability in length or size to accommodate child growth or other expandability needs, grasp locking capability, individual finger locking capability, three degree of freedom wrist joint, dynamic tensional rotation control of wrist, dynamic grasp control to allow grasping of irregular objects, extended grasp for gripping larger objects, excessive force breakaway, and algorithms to support by user of care-provider adjustment of the prosthesis.

Abstract: The invention is directed to a prosthesis which includes first and second members pivotally coupled together and two links which are pivotally coupled together with one link being pivotally coupled to the first member and the other link being pivotally coupled the second member. A control mechanism is provided which is pivotally coupled to the first member and the pivotal connection of the two links to move the two links and hence the second member relative to the first member. The first member may be coupled to a person to allow the prosthesis to serve in one embodiment as an arm or as a portion of an arm and in another embodiment to serve as a leg or as a portion of a leg.
