Novel TMS (transcranial magnetic stimulation) positioning device

Abstract

The invention discloses a novel TMS (transcranial magnetic stimulation) positioning device, and the device comprises a positioning cap and a positioning cap fixing apparatus which is disposed on a bed body. The positioning cap is provided with a plurality of latitude lines, longitude lines staggered with the latitude lines and marking points, so as to carry out the locating of a head magnetic treatment position. The positioning cap is also provided with a left fixed rod and a right fixed rod. The positioning cap fixing apparatus comprises a fixed supporting plate which is fixedly connected to the bed body, and a moving plate which is installed on the fixed supporting plate. The center of the fixed supporting plate is provided with a hollow-out part, and the periphery of the fixed supporting plate forms a supporting part, wherein the shape of the hollow-out part is consistent with the shape of the moving plate. The moving plate consists of a fixed part and a heat placing part which is disposed at the fixed part. The periphery of the head placing part is provided with limiting plates, and the inner sides of the limiting plates serve as supporting parts. The limiting plates at two sides are provided with fixed rings, and the left and right fixed rods on the positioning cap are respectively fixed in the fixed rings. The device facilitates the positioning in a transcranial magnetic treatment process and the maintaining of the position of a head in a treatment process, so as to guarantee the treatment effect.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a novel transcranial magnetic stimulation positioning device. Background technique [0002] Transcranial Magnetic Stimulation (TMS) is a method of cortical stimulation. The magnetic signal can pass through the skull without attenuation to stimulate the brain nerves. In practice, it is not limited to the stimulation of the brain. Peripheral nerves and muscles can also be stimulated. Stimulation, so it is now called "magnetic stimulation". Magnetic stimulation is a form of physical stimulation. It uses time-varying current to flow into the transcranial magnetic stimulation coil to generate high-intensity time-varying pulse magnetic field. The time-varying pulse magnetic field generates induced electric field and induced current in the tissue. The induced current makes some A stimulating method for excitable tissue to produce excitement, which has the advantages of painle...

Problems solved by technology

In the process of use, the operator mainly estimates the distribution of brain functional areas and the approximate position of body surface projection based on visual inspection and experience, and performs rough positioning. It is time-consuming and labor-intensive to locate the stimulation site by repeatedly moving the stimulation coil.

After finding the correct position, the patient's head is required to keep still during the whole stimulation treatment process, but because the shell of the 8-shaped coil and the hair are very slippery, the position between the head and the coil is easy to change, which will affect the treatment effect

For some patients who cannot sit for treatment and need to use lying treatment, a transcranial magnetic stimulator dedicated to lying treatment is required, which increases the treatment cost of the hospital and patients
