Master-slave control-based hand function reconstruction device and implementation method thereof

Abstract

The invention discloses a master-slave control-based hand function reconstruction device and an implementation method thereof and belongs to the field of electronic science and a rehabilitation robot.The hand function reconstruction device includes an electromyographic signal collection module, a microprocessor module, an action decoding module, a stimulation pulse encoding module, a stimulationwaveform generation module, a memory module, a press key module and an array stimulation electrode. A hand function reconstruction method includes the following steps of: utilizing an electromyographic signal of an uninjured side forearm surface of a patient as a control source for function reconstruction; and controlling an electrostimulation system to stimulate affected side forearm muscle according to an accurate stimulation sequence, stimulation intensity, stimulation pulse width and stimulation channel to make muscle contract to achieve a function reconstruction purpose. The master-slavecontrol-based hand function reconstruction device and the implementation method thereof have the advantages of high degree of hand function reconstruction, intellectualization, strong practicality, and the like; the patient can independently perform various hand movement training at home; and the application value is high.

Description

technical field [0001] The invention relates to a hand function reconstruction device based on master-slave control and a realization method thereof, belonging to the fields of electronic science and rehabilitation robots. Background technique [0002] Cerebral stroke is a sudden cerebral blood circulation disorder. Hemiplegia is one of the most common manifestations of stroke. It is often accompanied by sequelae such as loss of hand motor function, slurred speech, and visual impairment on the same side, resulting in inability to take care of oneself . At present, there are two methods for hand function reconstruction caused by hemiplegia. One is the biological method, that is, the distal stump of the damaged nerve is sutured to the side wall of the adjacent normal nerve trunk, and lateral buds emerge from the normal nerve trunk. , the axon re-grows into the distal side of the injured nerve sutured laterally, so that the damaged nerve function can be restored to some extent...
