Passive AxonRotation unit for the Michelangelo hand.

The AxonRotation Adapter 9S501 allows passive pronation/supination. These functions support the patient during his or her daily activities and provide the highest rehabilitation value. The AxonRotation Adapter 9S501 promotes a physiologically correct body posture and reduces the need for unnatural, compensating body movements.

Passive, unlimited 360° pronation/supination of the Axon-Bus gripping component is possible from an activation moment > 2.0 Nm via the integrated ratchet system. There are 24 ratchet positions, one at every 15°, for this purpose.
