Prosthetic hand manipulation training
Release Time:
Nov 06,2021
Prosthetic hand manipulation training Opening and closing hand training: The cable-controlled prosthetic arm is opened by relying on the shoulders to bend forward, and the prosthetic hand is closed by elastic force when there is no force. The upper arm cable control prosthetic hand must lock the elbow joint in order to open the hand. Forearm electromyographic prostheses are often used by amputees to perform phantom limb exercises to forcefully open the hand, extend the wrist to control the opening of the hand, forcefully flex the fingers, and bend the wrist to control the closing of the hand. Prosthetic use training: The function of the human hand is a complex sensory feedback, a process of coordinated muscle movement. If the artificial hand function is really required to have practical value, it must be carefully trained. The myoelectric prosthetic hand is driven by a micro DC motor through a gear transmission mechanism to assist the fingers of the patient's hand movement. It is characterized in that: two EMG signal collection electrodes are set to fit the area where the EMG signal of the patient's arm is relatively active, and the EMG signals representing the opening and closing of the fingers are collected respectively, and the two EMG signals are input to the device including The control module, including the single-chip microcomputer and the motor drive circuit, outputs the opening and closing signals of the prosthetic hand by the single-chip microcomputer. The micro DC motor is driven to rotate forward or reverse through the motor drive circuit, and the prosthetic hand is closed or opened through the gear transmission mechanism, thereby driving the patient's hand. The department does opening and closing movements. Therefore, correctly placing the EMG sensor on the part with strong EMG signal selected by the technician is the most important point for the flexible use of EMG prosthetic hands.
