A three-dimensional positioning and navigation system and navigation method for transcranial magnetic stimulation of cerebral cortex

Abstract

The invention discloses a cerebral cortex transcranial magnetic stimulation three-dimensional positioning navigation system and method. The navigation system comprises a fixing device, a navigation device and an auxiliary positioning device, wherein the fixing device comprises a fixer, and the navigation device is arranged above the fixing device and comprises a first motor and a second motor driven by the first motor; the auxiliary positioning device comprises a conformal mask and positioners arranged around the conformal mask, and positioning holes are formed in the conformal mask; the first motor and the second motor are connected to one controller. According to the navigation method, through a coordinate conversion method, the position of a nidus in a scintigram is made to correspond to the position in an actual coordinate system, then, the motors are driven for navigation, and a basis is laid for subsequent treatment. Through the device and method, the nidus can be accurately and rapidly positioned and stimulated, and good equipment and a good research idea are provided for transcranial magnetic stimulation treatment.

Description

technical field [0001] The invention relates to the technical field of craniocerebral surgery, in particular to a three-dimensional positioning and navigation system for cerebral cortex transcranial magnetic stimulation. Background technique [0002] Transcranial Magnetic Stimulation (TMS) is a method that uses pulsed electromagnetic fields and alternating electromagnetic fields to act on the central nervous system of the brain, and uses electromagnetic induced currents to change the membrane potential of neurons in the cerebral cortex, affecting brain metabolism and Nerve potential activity, thus causing a series of physiological functions to respond, this method has the advantages of painless, non-invasive, easy to operate, safe and reliable, etc. Stroke, schizophrenia (negative symptoms), depression, obsessive-compulsive disorder, mania, post-traumatic stress disorder (PTSD), neurorehabilitation, pediatric cerebral palsy, cognitive impairment, mental depression, epilepsy ...

AI Technical Summary

Problems solved by technology

This process is time-consuming and labor-intensive. Not only is it difficult to repeat the exact stimulation of the same target point between stimulation experiments (or treatments), but the reliability of the test results also needs to be verified, because the stimulation depth and stimulation angle cannot be directly determined from the scalp surface. , can be said to be in a state of "blind stimulation"

[0004] In addition, the existing cranial magnetic stimulation can only stimulate inaccurately specific positions because there is no precise navigation. Since the intracranial and extracranial positions cannot be exactly unified, the probe cannot be brought to the target area. The most suitable location, unable to form a systematic treatment and research plan
