Paralytic patient auxiliary nervous pathway restoring system

Abstract

The present invention relates to an auxiliary nervous channel recovery system for paralytic patient. It includes successively-connected brain wave signal collecting device, brain-machine interface control device, functional electrostimulant signal generator device and multilead stimulation electrode, in which the brain wave signal collecting device is used for collecting and processing brain wave signal and producing digital brain wave signal; the brain-machine interface control device can be used for making spectral analysis and mode identification of digital brain wave signal and producing functional electrostimulant switching control signal; the functional electrostimulant signal generator device can be used for producing functional electrostimulant drive signal according to the received functional electrostimulant switching control signal to drive multilead stimulation electrode; and the multilead stimulation electrode can be mounted on the lower limb of patient, and can be used for driving peripheral nervus motorius of leg muscle to produce leg motion.

Description

technical field [0001] The invention belongs to the field of rehabilitation biomedicine, and relates to an auxiliary nerve channel recovery system for paralyzed patients. Background technique [0002] Paraplegia is a severe disability of the lower limbs caused by spinal cord injury, and its incidence has shown a significant upward trend in recent years. Since the spinal cord is in charge of information transmission between the brain and other parts of the human body (especially the limbs), its damage will directly lead to nervous system disorders below the wound, resulting in paralysis of the corresponding limbs. In addition, its regenerative ability is quite weak, and clinical treatment methods are very limited. Functional Electrical Stimulation (FES) technology is generally considered to be an effective clinical tool in the restoration of walking ability of paraplegic patients. FES technology is to install a stimulation device at the paralyzed limb, and stimulate the musc...

AI Technical Summary

Problems solved by technology

But so far, the motor nerves reconstructed by FES technology are limited to the peripheral motor nerves that drive the leg muscles. At present, there is no central nerve connected to the patient's brain, and it cannot be regarded as an independent, autonomous and complete motor nervous system.

Therefore, the existing FES control signal can only be given passively by the outside world, and its motor nerve reconstruction control mode cannot express the patient's subjective motor consciousness, so it has fatal weaknesses such as poor adaptability, easy to be disturbed, and difficult to learn and master, which restricts FES The motor nerve reconstruction effect of the technology has become a bottleneck problem to be solved in the clinical promotion and application of rehabilitation
