Microprocessor-Controlled Arm Prosthesis PR4-MPU.1 for Upper Limb Amputation

The shoulder prosthesis with external energy source PR4 is used in case of amputation of the upper limb at the shoulder level, including underdevelopment. The receiving sleeve is made of laminated plastic from an individual plaster cast. Geometric fixation of the prosthesis due to the shape of the residual limb.

The wrist joint allows rotation of the hand. Myoelectric hand: with the possibility of controlling the hand either from two or one electrode for patients with one functional muscle group, with proportional control of the speed and force of the grip, ensuring natural and coordinated work of the fingers, with increased speed and accuracy of movements, guaranteeing the fulfilment of the grip/gestures of the artificial hand. Thumb with flexion in the joints of the first phalanx, with electronic control of extension/retraction and flexion/extension.

The prosthesis utilises an elbow joint.
