Problems solved by technology

And when the therapy is used in humans, it also needs to suppress a person's immune system, which in itself poses some serious problems
[0006] Other experiments have also shown that the stem cell approach is ineffective for repairing nerve bundles damaged for more than 6 months

Embodiment 1

[0019] A microelectronic system-assisted neural channel functional reconstruction method for detection and regeneration of sensory, motor and visceral signals in vertebrates including humans, including functional reconstruction of descending neural channels and functional reconstruction of ascending neural channels, descending neural channels Functional reconstruction is to apply a descending nerve signal detection electrode at the proximal end of the damaged nerve bundle or nerve fiber, amplify, identify and extract the detected weak nerve signal, and then output the extracted nerve signal to the downgoing exciter. The descending stimulator forms a functional electrical stimulation signal, and then applies it to the stimulating electrode of the descending signal, so as to regenerate the biological nerve signal on the distal damaged nerve bundle or nerve fiber; Apply the upward nerve signal detection electrode to the distal end of the nerve to amplify, identify and extract the ...

Embodiment 2

[0022] This embodiment is a device for implementing the above microelectronic system-assisted neural channel function reconstruction method, at least including one downlink neural channel function reconstruction branch 1 and one uplink neural channel function reconstruction branch 2, that is, it can be multiple One downlink neural channel function reconstruction branch 1 and multiple uplink neural channel function reconstruction branches 2, for example: 2, 4 or 8 channels can be selected according to needs, the above-mentioned downlink neural channel function reconstruction branch includes The proximal detection electrode 11, the descending nerve signal amplifier 12, the descending nerve signal processor 13, the descending exciter 14 of the proximal motor nerve signal of the damaged nerve bundle or nerve fiber are used to implement functions to the far-end nerve bundle or nerve fiber The downstream distal stimulating electrode 15 for electrical stimulation is detected by the do...

Abstract

The present invention discloses method and apparatus of detecting, exciting and regenerating sensation, motor and internal organ signals of vertebrate including human, and is especially one kind microelectronic system aided nerve channel function recovering method and apparatus. The nerve channel function recovering apparatus includes two parts, one part for the function reconstruction of the ascending nerve channel and the other part for the function reconstruction of the descending nerve channel. The weak electric signal of the damaged nerve tract or nerve fiber is detected with detecting electrodes, amplified, recognized and extracted to generate controlled electric exciting signal for exciting the damaged nerve tract or nerve fiber to regenerate corresponding nerve signal and restore the function of the damaged nerve tract or nerve fiber micro electronically.

Description

technical field [0001] The invention relates to a method and device for detecting, stimulating and regenerating sensory, motor and visceral signals of vertebrates including humans, in particular to a microelectronic system-assisted nerve channel function recovery method and device thereof. Background technique [0002] Nerve injury and regeneration has always been an important topic in neuroscience research. Nerve regeneration in the true sense should be the reconnection of interrupted nerves along the original channels at the proximal and distal ends through the division and proliferation or automatic growth of nerve cells. Recently, a research team led by Professor Anderson of the University of California, Irvine, has made progress in using human neural stem cells to repair spinal cord injuries in mice ("Science Times" September 23, 2005). However, this experiment has the following problems: [0003] 1) They injected human neural stem cells 9 days after spinal nerve inju...
