Myoelectric bionic arm system based on nerve redistribution technology

Abstract

The invention discloses a myoelectric bionic arm system based on nerve redistribution technology. The aim is to overcome the lack of functions of existing bionic arms and the inability to control the entire artificial arm with myoelectric signals. It includes a tactile sensor, a tactile signal amplifying circuit and a tactile signal filter circuit, which are connected by wires in turn; The motor is fed into the motor and connected by wires in turn; it also includes a level conversion chip and a PC, and the single-chip microcomputer and the level conversion chip are connected to the PC by wires in turn. The tactile sensory signal filter circuit is connected with the electric wire of the level conversion chip. The myoelectric electrodes are pasted on the skin of the chest muscles, the tactile sensor is installed on the artificial finger, the level conversion chip and the PC are removed after the system is debugged, and other components are installed on the artificial arm. The single-chip microcomputer controls the stepper motor 17 to rotate and stop according to the myoelectric signal and the tactile sensation signal, so as to realize the control of the artificial arm.

Description

technical field [0001] The invention relates to a control device of a prosthetic arm using information and bionic control technology, more specifically, it relates to a myoelectric bionic arm system based on nerve redistribution technology. Background technique [0002] For the disabled, the old-fashioned prosthetic hand is largely a display, unable to transmit any sensory signals, so the disabled must use their eyes rather than their consciousness to hold things. The myoelectric bionic arm system based on nerve redistribution technology, for people who have lost their entire arm, puts the nerve in the chest muscle through surgery, converts the nerve signal into the myoelectric signal of the chest muscle, and controls multiple degrees of freedom through the myoelectric signal The bionic arm enables the disabled to control the movement of the arm through consciousness, so that the bionic arm can move freely and precisely, and at the same time obtain the long-lost sense of tou...
