FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine, namely to devices of a single-grip electromechanical prosthetic hand. The device consists of an electric motor, a multi-stage or single-stage gear cylindrical transmission, a worm and a worm wheel. The drive gear of the gear system is connected to the shaft of the electric motor. The worm wheel, the thrust and the artificial thumb of the grip form an articulated four-link mechanism. The possibility of changing the forming shells without disassembling the mechanism is achieved, ensuring the protection of mechanical transmission parts from damage and contamination, while the design provides a grip force above 35 N.
EFFECT: new solutions in prosthetics.
