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 electromechanical hand, should-plate 1, sensors, actuators, independent and communication control channels, flat links: kinematic arm and forearm analog, drive limit switches; adders, function generators 24, 25, 26, 27, power amplifier 16, master rotors 21, 32, 33, stators 36, 37, flexible members 34, 35, rollers 63, control ropes 66, belt 70, coordinate input bracket 41. Control circuits represent positioning systems 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 clebicle and scapula, and as prosthesis for children. Fragmentarily the device can be used at other levels of amputation of the upper extremities. EFFECT: reduced tension in work of the operator-invalid, approached functioning of the prosthesis to the natural one, reduced time of working operations, enhanced control quality, reduced mass of actuator and its power consumption. 2 cl, 2 dwg
