The PIPDriver is a body-driven mechanical finger, designed to restore length and dexterity using the intact PIP joint to provide DIP flexion/extension. This custom-designed prosthesis mimics the anatomical motion of the finger, as it is driven by the residuum using a self-suspended linkage system.

This prosthesis is intended for use on a finger absence at or just proximal to the distal interphalangeal (DIP) joint, where there is some joint range of motion and enough residual digit to engage the distal suspension ring at the PIP joint.
