Abstract

Development of a prosthetic hand for an above-the-wrist amputee. The hand will provide flexion and extension of the wrist, fingers and thumb. The device will be customized for each individual by utilizing an medical imaging of the amputation side stump and the normal arm/wrist as the input. An integral hand/wrist and socket will be 3D printed, and actuators will be mounted to the prosthetic to provide motion. The wrist will be a mirror-image of the normal hand. Materials utilized will be selected based on the medical image intensity for different tissue types (cartilage, bone, skin, fat, etc.) and will simulate the mechanical properties of the human tissue. The function of tendons and muscle will be accomplished by attaching external stainless-steel wires to simulated bone insertion points by passing them through a self-lubricating and protective sheath (integral to the hand/socket) and connected to the actuators manually. As a goal, the hand will have physiological finger/thumb grip strength and torque development at the wrist.
