Neurostimulation rehabilitation system and neurostimulation method based on motor intention

Abstract

The present invention provides a nerve stimulation rehabilitation system and a stimulation method based on motion intention, the system comprising: an in vitro control system, including: an EMG acquisition module, which collects surface muscle electrical signals generated by the patient's healthy side limbs; an in vitro micro-control module, which analyzes The amplitude and duration of the collected myoelectric signal waveform and the order to control the stimulator in the body; and the first wireless communication module; the implanted system in the body, including: the micro-control module in the body, which controls the stimulation order; the stimulator in the body, according to Stimulation commands are analyzed to generate stimulation waveforms; DC‑DC conversion module supplies power to each module circuit; power amplifier module amplifies the stimulation waveform generated by the internal stimulator after analyzing commands in the range of +5V to ‑5V for positive and negative charge balance waveform transmission to the stimulation electrode; the stimulation electrode generates a nerve impulse to the corresponding nerve; and the second wireless communication module. The system stimulates the nerves of the affected limb by preserving the limb on the motor side.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a nerve stimulation rehabilitation system based on motion intention and a nerve stimulation method using the system. Background technique [0002] Implanted nerve stimulation system technology is relatively mature in the world at present. The current mature products in the world include implanted vagus nerve stimulators, implanted spinal cord stimulators, and implanted nerve stimulators. Most of these types of systems are powered by batteries. It consists of a controller, a DAC conversion module, a stimulation module and a wireless communication module. Then, the medical staff monitors the patient's condition externally and performs appropriate electrical stimulation on the corresponding target nerves according to the judgment of the medical staff, so as to achieve the purpose of corresponding neural regulation. For example, the patent CN200910312370 discloses a master-s...

Problems solved by technology

[0004] In order to solve the technical problem that the current hemiplegia stimulation only performs nerve stimulation under the consciousness of the medical staff, but does not carry out nerve stimulation regulation under the patient's autonomous consciousness, resulting in inaccurate mapping of the patient's brain consciousness and limb movement, the present invention provides a method based on The nerve stimulation rehabilitation system of motor intention and the stimulation method applied by the system, the system can stimulate the nerves of the limbs on the affected side to achieve the patient's autonomous rehabilitation movement by preserving the limbs on one side of the motor function
