MULTIFUNCTIONAL ACTIVE ARM PROSTHESIS Russian patent published in 1996 - IPC

FIELD: prosthetics of upper extremities. SUBSTANCE: the prosthesis uses the arm and forearm links, artificial electrical hand with an electric drive, shoulder-plates 1, sensors, actuators, independent and communication control channels, flat links: kinematic forearm analog, limit switches of drives 40, 41, adders 33, function generators 38,39, power amplifiers 23, master rotors and stators, flexible member 49, rollers and control ropes, belt and bracket-retainer of coordinates of the origin secured on it. The control channels represent servo positioning drives with coordinated control. The prosthesis can be used after one-sided and two-sided exarticulation of the humeral articulations, as well as after exarticulation of the clavicle and scapula. Fragmentarily the device can be used at lower levels of amputation. EFFECT: reduced time of working operations and enhanced control quality, accuracy inclusive, reduced tension of invalid mental state, approached prosthesis functioning to the natural one. 2 cl, 2 dwg
