Problems solved by technology

In the early stage of rehabilitation training for patients with hand dysfunction, the patient is still unable to control the hand movement autonomously, and needs external force to assist the hand movement. At present, there is no such device to help the patient carry out independent special rehabilitation training. Regarding the hand dysfunction patient How to use myoelectric signals to control myoelectric prosthetic hands and carry out autonomous rehabilitation training for oneself is still a blank

Abstract

Disclosed is a myoelectric prosthetic hand for self-rehabilitation training of patients with hand dysfunction. A miniature direct-current motor drives fingers, which are used for assisting hand movement of a patient, of a mechanical prosthetic hand via a gear transmission mechanism. The myoelectric prosthetic hand is characterized in that two myoelectric signal acquisition electrodes are attached on areas, with more active myoelectric signals, of an arm of the patient and are used for respectively acquiring finger unfolding and folding myoelectric signals, the two myoelectric signals are inputted to a control module comprising a single chip microcomputer and a motor driving circuit, the single chip microcomputer outputs unfolding and folding signals of the prosthetic hand, the motor driving circuit drives the miniature direct-current motor to forwards rotate or reversely rotate, and the gear transmission mechanism drives the prosthetic hand to be folded or unfolded so as to drive the hand of the patient to be unfolded and folded.

Description

technical field [0001] The invention relates to a prosthetic manipulator designed based on the principle of myoelectric signals, in particular to a myoelectric prosthetic hand used for rehabilitation training of patients with hand dysfunction caused by stroke and other diseases, belonging to signal acquisition and processing related to manipulators, computers, motors, etc. Control and other technical fields. Background technique [0002] Although myoelectrically controlled prosthetic hands have appeared for many years, basically all myoelectric prosthetic hands are used as a substitute for the missing arm of the disabled to compensate for the missing hand function of the disabled. No myoelectric prosthetic hand is used for diseases such as stroke Hand rehabilitation training for patients with hand dysfunction. In the early stage of rehabilitation training for patients with hand dysfunction, the patient is still unable to control the hand movement autonomously, and needs ext...
