Multi-point multi-frequency three-dimensional transcranial magnetic stimulation system and intracranial and extracranial coordinate conversion method

Abstract

The invention discloses a multi-point multi-frequency three-dimensional transcranial magnetic stimulation system and an intracranial and extracranial coordinate conversion method. The system comprises a fixing device, a stimulation device and an auxiliary positioning device, wherein the fixing device fixes the neck position of a patient, the stimulation device carries out fixed point magnetic stimulation on the patient, and the auxiliary positioning device is used for determining a positioning point in an auxiliary way for realizing the intracranial and extracranial coordinate conversion. Meanwhile, the coordinate conversion method provided by the invention can conveniently and fast realize the intracranial and extracranial coordinate conversion, and is matched with the system, and an all-around automatic transcranial magnetic stimulation treatment scheme is provided. The device has the advantages that the structure is simple, the function is practical, an effective device is provided for transcranial magnetic stimulation treatment, and a novel study idea is provided.

Description

technical field [0001] The invention relates to the technical field of craniocerebral surgery, in particular to a cerebral cortex transcranial three-dimensional magnetic stimulation system, which can automatically perform single-point, single-frequency, multi-point, multi-frequency and other magnetic stimulation treatments on lesion positions. 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-trauma...

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"
