ELECTROMECHANICAL EXECUTIVE UNIT OF TRAINING DEVICE FOR DEVELOPING ARTICULATIONS Russian patent published in 2001 - IPC

FIELD: medical engineering. SUBSTANCE: device has electromotor with actuating mechanism, gauge for determining output shaft position and output shaft loader and force control unit. The output shaft loader is cylinder with radial holes for pistons arranged radially relative to the output shaft and engageable with it through linking members. Cavities of the cylinder are integrated as hydraulic system united with single-sided cylinder which piston is connected to the force control unit output unit having transmission of screw-nut type, spiral compression spring, the second electromotor with mechanical transmission and output unit produced as supporting member movable in axial direction. The spring thrusts against the output unit and nut. The screw is connected to the second electromotor through mechanical transmission. The nut has cylindrical guide member on its side to enable translation motion only. The nut is rigidly connected to force gauge engine through screw-type master form. The master form screw is rigidly connected to force transducer engine. EFFECT: controllable load applied to injured joint; enabled vibration loading. 1 dwg
