Mechanical (Body-Powered) Prostheses
Durable arm prostheses operated by shoulder and trunk movements, with no power source needed.
Mechanical prostheses transfer the user’s shoulder and trunk movements to the prosthetic hand or hook through a cable and harness system. They need no batteries or charging, are durable and can be used confidently for physical work.
Who are they for?
- Users who prioritize durability and low maintenance
- People working in environments unsuitable for electronics
- Users who will rely on the prosthesis actively for long hours
Components
A custom socket, harness and cable system, an elbow unit at the levels that need one, and a hand or hook as the terminal device. The terminal device can be changed depending on the task.
Frequently asked questions
