Transcranial magnetic stimulation positioning cap and marking method thereof

Abstract

The invention discloses a transcranial magnetic stimulation positioning cap, which comprises a shell body adapt to the shape of a human brain, wherein the shell body is correspondingly provided with marking portions used for making two cerebral hemispheres, four brain lobes, EEG electrode parts, a motor cortex functional area, earholes for capping positioning and occipito posterior tuberosity. The transcranial magnetic stimulation positioning cap and the marking method thereof are low in implementation costs, thus medical expenses of patients are reduced; and the operation is convenient, time and effort are saved, and utilization rate of the equipment is increased. Multi-part marking information in the positioning cap makes stimulation parts accurate, the positioning description and repetitive stimulation of the stimulation parts are facilitated in scientific research. The uncertainty of traditional stimulation positioning relying on visual observation and experience is eliminated, and function modulation and therapeutic effect of stimulation nerves can be improved.

Description

technical field [0001] The invention relates to the technical field of transcranial magnetic stimulation, in particular to a transcranial magnetic stimulation positioning cap composed of brain lobes, distribution of brain motor function areas, and an electroencephalogram electrode positioning system and a marking method thereof. Background technique [0002] Transcranial magnetic stimulation technology is a method of non-invasive brain stimulation and nerve function modulation. Using the principle of electromagnetic induction, it is charged by a high-voltage energy storage capacitor and discharged to the stimulation coil in a very short time. A strong current generates an instantaneous The changing magnetic field can pass through the skull without loss, generate an induced current in the brain, stimulate the depolarization of local brain nerve cells, or affect the local potential, change the changes in nerve metabolism and cerebral blood flow, and produce a series of physiolo...

Problems solved by technology

[0006] Initially, users use their own medical knowledge, based on visual inspection and experience, to estimate the distribution of brain function areas and the approximate location of body surface projections for rough positioning. It is necessary to repeatedly move the stimulation coil to find the stimulation site, which is time-consuming and laborious, and the result is not very satisfactory. , with the development of technology, a frameless infrared navigation system under the guidance of MRI has appeared in foreign countries. The robot hand repetitive stimulation positioning auxiliary device and the accuracy of stimulation positioning are relatively good, but due to high cost and time-consuming operation, it increases medical costs and limits In clinical promotion; there are also simple magnetic stimulation positioning caps in China, but only the body surface projection of the motor area of ​​the brain cannot meet the clinical positioning needs of multiple diseases and multiple parts stimulation, and cannot be combined with real-time EEG recording and Compatible with the development trend of the feedback, unable to describe the stimulation site in detail

Therefore, the application value is limited
