TMES (transcranial magnetic electric stimulation) device

Abstract

The invention provides a TMES (transcranial magnetic electric stimulation) device. The TMES device comprises at least one pair of internal electrodes inlaid in skull, wherein the internal electrodes are made of a magnetic NdFeB material wrapped with a titanium alloy; a first internal electrode inlaid in left temporal skull and a first external electrode detachably arranged on left temporal scalp of the skull can be electrically connected through the scalp; a second internal electrode inlaid in right temporal skull and a second external electrode detachably arranged on right temporal scalp of the skull can be electrically connected through the scalp; the first external electrode and the second external electrode are connected to an anode and a cathode of a pulse generator through wires respectively. The TMES device is simple, safe, low in cost, convenient to use, good in curative effect and wide in treatment range and has few side effects, craniotomy is avoided for an operation, and abnormal electric activities of brain nerve fibers are changed under physical actions of a magnetic field and an electric field, so that a series of nervous system diseases caused by the abnormal electric activities are treated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a separate brain pacemaker. Background technique [0002] The movement of the human body is completed by the contraction and relaxation of the muscles. The contraction and relaxation of the muscles are realized by receiving the electrical signals from the brain center. There are two centers for commanding and coordinating body movements, namely the pyramidal system and the extrapyramidal system. The electrical signal instructions of specific frequency and amplitude reach the target through the descending nerve fibers, command and coordinate the contraction and relaxation of muscles, and maintain the normal state of muscle strength and muscle tension. If the above two centers are over-reactive under the action of pathogenic factors, they will send out excessively strong abnormal electrical signals. The target muscles receive such excessively strong electrical signals and e...

AI Technical Summary

Problems solved by technology

[0004] The main disadvantages of DBS are: 1. High risk of operation: DBS pulse generator, wire and internal electrodes are connected together, all need to be implanted in the body, and the risk of craniotomy is high

2. Expensive: The material requirements for implantation in the body are high, the price is expensive, the operation is large, and the medical expenses are high
