Myoelectric prosthetic hand for rehabilitation training of patient suffering from hand dysfunction

The utility model discloses a myoelectric prosthetic hand for rehabilitation training of the patient suffering from hand dysfunction. In a mechanical prosthetic hand, a miniature direct current motor drives fingers for assisting hand motion of the patient through a gear transmission mechanism. The myoelectric prosthetic hand is characterized in that: two myoelectric signal acquisition electrodes are attached to areas in which myoelectric signals are active on an arm of the patient, acquire myoelectric signals representing that the fingers are opened and closed, and inputs the two myoelectric signals to a control module comprising a singlechip and a motor drive circuit; the singlechip outputs prosthetic hand opening and closing signals, the miniature direct current motor is driven to rotate positively or reversely through the motor drive circuit, and the prosthetic hand is closed or opened through the gear transmission mechanism, so that the hand of the patient is driven to perform opening and closing motion.
