Embedded nerve electrode for recovering eyes-closed function and control system

Abstract

The invention relates to the recovery filed of the medical nerve function, in particular to an implantation type nerve electrode and a control system thereof used for recovering an eye closed function. The implantation type nerve electrode and the control system thereof comprise an electrode and a controlling circuit, and are characterized in that the electrode comprises a silica gel sleeve pipe and two round electrodes fixed at the both ends of the silica gel sleeve pipe, the two round electrodes are respectively provided with electrode outgoing lines, the electrodes are implanted into the periphery of a facial nerve branch responsible for dominating a musculus orbicularis oculi, the electrode outgoing lines are axially led out along the silica gel sleeve pipe and penetrate a subsurface, to be reserved at the concealed part of a human body, and to be connected with a neuroelectricity stimulation control device, the neuroelectricity stimulation control device inputs stimulation wave signals to the electrodes. The implantation type nerve electrode and the control system thereof used for recovering the eye closed function can ensure muscle to generate various optional and normal functional movements, to prevent the muscle paralysis from being caused due to the damage of the facial nerve function.

Description

technical field [0001] The invention relates to the field of medical neurological function restoration, in particular to an implanted nerve electrode and a control system for restoring eye-closing function, which restores the eye-closing function of patients with facial paralysis by means of functional electrical stimulation. Background technique [0002] Nervous system is a highly complex information processing and motor control system. Human life activities are completely dependent on the normal regulation and control of the nervous system. If there is a problem in any link in the nervous system, human life activities will be hindered. even death. The problem to be solved by Functional Neuromuscular Stimulation (FNS) or Functional Electrical Stimulation (FES) technology is just one of many problems to be solved in the complex nervous system. In stroke, brain injury, tumor or spinal cord injury, the conduction of high-level motor neurons in the nervous system will be block...

AI Technical Summary

Problems solved by technology

If the facial nerve defect is large and the tension is too high, it cannot be sutured directly. At present, there is no effective treatment method to restore the damaged facial nerve function and relieve the symptoms of facial paralysis. The patient will have permanent facial paralysis. The reason is the regeneration of the nerve. It is still a worldwide unsolved problem, just like the limb muscle paralysis caused by spinal cord and other high-level neuron injuries. Although people are constantly exploring, trying nerve transplantation, inducing nerve regeneration and other treatment measures, they are still unable to fully recover. Injury to the function of the nerves, causing the muscles to produce voluntary and normal various functional movements
