DEVICE FOR POSITIONAL SENSING OF ARTIFICIAL HAND FINGERS MOBILITY Russian patent published in 2020 - IPC A61F2/54 A61F2/70 

FIELD: medicine.

SUBSTANCE: invention relates to medicine. Device for positional sensing of movability of fingers of an artificial hand comprises a base with longitudinal grooves into which spring-loaded contact elements of two activators are inserted with possibility of longitudinal movement, kinematically connected to a drive system. Activators movement mechanism is made in the form of a cable transmission comprising the first flexible cable fixed on one side in the groove of the small transmitting pulley of the double pulley block hinged on the base, and on the other hand is connected to the active artificial hand finger mechanism. Active artificial hand is equipped with an electromechanical or mechanical drive device. First flexible rope is placed in a flexible resilient guide fixed on one side on the hand body, and on the other side on the basis of the positional sensing device. Second flexible cable is fixed in groove of pulley of larger diameter and is kinematically connected to distribution pulley hingedly installed on base, forming two branches of rope transmission of opposite directed motion, and is attached to the end of a return tension spring, the second end of which is rigidly connected to the base. One activator is attached to one of the branches of translational movement, and the second one to branch of opposite movement direction.

EFFECT: invention provides simplified design of the device while maintaining its functional properties.
