Deep brain stimulation system based on magnetic stimulation

Abstract

The invention discloses a deep brain stimulation system based on magnetic stimulation. The system comprises stimulating electrodes implanted in a brain, electrode receiving coils connected with tail parts of the stimulating electrodes and inlaid in skull broken holes, stimulation transmitting coils arranged above the electrode receiving coils, and a pulse generator connected to the outside. The deep brain stimulation system can reduce the cost of equipment and prolong the service life of the equipment, the operation difficulty is low, and a side effect on a patient is small.

Description

technical field [0001] The invention relates to the technical field of deep brain positioning magnetic stimulation, in particular to a deep brain stimulation system based on magnetic stimulation without embedding a pulse generator in the chest. Background technique [0002] At present, brain neurofunction modulation includes noninvasive transcranial magnetic stimulation (transcranialmagneticstimulation, TMS) and invasive deep brain stimulation (Deepbrainstimulation, DBS). TMS uses the principle of electromagnetic induction to discharge the energy-storing high-voltage capacitor to the stimulation coil through the electronic switch. The stimulation coil generates a transient magnetic field that passes through the skull, induces an induced current in the superficial cortex of the brain, stimulates the intracranial nerve, and causes the nerve cell membrane potential. Changes and changes in excitability regulate nerve function. The intensity of magnetic stimulation decreases exp...

AI Technical Summary

Problems solved by technology

[0006] 1. High equipment cost;

[0007] 2. The pulse generator of DBS needs to be powered by batteries, and the battery life is limited. Replacing the batteries requires a second operation, and the cost of external charging is higher

[0008] 3. Doctors are required to have high surgical skills, high difficulty and long operation time

[0009] 4. The patient has a large wound, and foreign objects must be embedded from the head to the neck to the chest, which will cause surgical damage; there are many side effects, and the stimulator and connecting wire will be rejected, pain and other discomforts when embedded as foreign objects in the body.
