FIELD: prosthetics.
SUBSTANCE: mechanical anthropomorphic manipulator comprises an artificial palm and fingers pivotally connected to the artificial palm formed by three pivotally connected hollow phalanges, tension cords of the artificial fingers. The device comprises a forearm sleeve equipped with pressure pneumatic stops, a manual pneumatic pump and tubes connecting the pneumatic pump with pressure pneumatic stops and a telescopic extension. The telescopic extension is inserted into the forearm sleeve configured for rotation around its axis. At the outer end of the telescopic extension, an artificial hand is mounted, comprising expansion stops, and the expansion stops are attached inside each phalanx at its lower point. The inner end of the telescopic extension is equipped with a control lever of the telescopic extension, on which there is a switch of a manual pneumatic pump, a lever of a manual pneumatic pump and control stops with fixation rings, on which coils with tension rods wound on them are mounted, the free end attached to the extreme internal points of artificial fingers configured for compressing artificial fingers when compressing the control stops. The coils are equipped with an automatic winding mechanism and a tension rod blocking mechanism formed from corrugated plates connected to each other by springs on the sides. Between the plates there are tension rods configured for locking the tension rods when the control stops are compressed, and the telescopic extension is equipped with a return harness.
EFFECT: device that does not require the use of external energy sources, with a large elongation range, the use of which makes housekeeping easier and increases the functionality of people with disabilities.
