Body Powered Wrists and Terminal Devices
Every upper extremity prosthesis has some type of terminal devices, its selection largely dependent on the kind of tasks most often performed. These devices can range from natural appearing hands to high-tech hook closures or custom-shaped receivers for sports or recreational equipment.
Almost every prosthetic manufacturer makes hooks, hands, and wrists. A small sampling includes:
Hosmer hooks are forged and machined to exacting specifications to provide a high degree of quality and performance. As a result, Hosmer terminal devices have developed an international reputation for their rugged durability. The wide variety of configurations allows the practitioner to clinically match the patient needs and performance goals to achieve maximum independence.
Hosmer pediatric hooks have canted tines for better visual feedback. This allows the user to pick up paper, coins and other small fine objects from the side with ease. The UCLA CAPP TD was designed for children. Made of molded plastic, this terminal device provides a wide palmar face with a tactile, resilient covering allowing a secure hold on odd shapes such as toys. An internal spring provides prehension. The spring can be changed to accommodate a light or heavy prehension.
College Park’s Body Powered Gripper has curved jaws allowing spherical and cylindrical objects to be held firmly. Two levels of grip can be selected by simple user control. This item requires a hand connection plate.
