Upper Limb Prosthetics - Body-Driven

The ThumbDriver is a body-driven mechanical thumb, which uses a unique anchor design to restore the grasp capabilities of the hand. Designed with the functionality of the entire hand in mind, the ThumbDriver works in conjunction with the fingers to provide the key oppositional force required when grasping or gripping objects.

The ThumbDriver is intended for use by those with a thumb absence between the MCP and IP joint. There must be natural motion present in the individual’s CMC and/or MCP joints, along with enough residual digit to engage the distal suspension ring, allowing the device to provide a rigid opposition to any heavy forces generated by the finger.
