Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] see figure 2 As shown, a double-8-shaped transcranial magnetic stimulation coil of the present invention is composed of two 8-shaped coils with different winding radii connected. The centers coincide, the same current I flows through the two coils, and the direction of the current I is in the same direction at the center, which plays a role in strengthening the field strength at the center. The double 8-shaped transcranial magnetic stimulation coils are connected to a pulse power supply, and under the action of current, a high-focus alternating magnetic field is generated, which can be used for transcranial magnetic stimulation experiments and treatments. The double 8-shaped coil of the present invention can be made by winding various metal wires, and the coils are arranged in a way that does not shield the electromagnetic field. figure 2 structure...

Abstract

The invention relates to a double butterfly transcranial magnetic stimulation coil. The coil is formed by connecting a first butterfly coil and a second butterfly coil; the center of the first butterfly coil is coincided with the center of the second butterfly coil in space; two circular coils, of which the radii are Ri, of the second butterfly coil are positioned in two circular coils, of which the radii are Ro, of the corresponding first butterfly coil; and the Ro is greater than the Ri. According to the double butterfly transcranial magnetic stimulation coil, the two circular coils of which the radii are small are arranged inside the traditional butterfly coil, the spatial position of a conductor, and the radii of inner and outer coils and number of turns of the inner and outer coils are set, so that focusing degree of coil stimulation is improved; and the double butterfly transcranial magnetic stimulation coil is concentrated in stimulation range and high in pertinence, and the possibility of stimulating unrelated nervous tissues is obviously reduced.

Description

【Technical field】 [0001] The invention belongs to the technical field of transcranial magnetic stimulation, in particular to a transcranial magnetic stimulation coil with a double-8-shaped structure. 【Background technique】 [0002] Transcranial magnetic stimulation (TMS) is a non-invasive biostimulation technology that uses a time-varying magnetic field to generate an induced electric field, causing biocurrent to conduct in tissues, thereby depolarizing nerve fibers, neurons, and muscles. It is used to change the action potential of cortical nerve cells, affect the metabolism and nerve electrical activity in the brain, so it can be used to treat a considerable number of neurological and mental diseases. Diseases that can currently be treated with TMS include aphasia, tinnitus, Parkinson's disease, dystonia, amyotrophic (spinal) lateral sclerosis, epilepsy, migraine, speech disorders, hemispatial neglect, phantom limb pain, Chronic pain, obsessive-compulsive disorder, etc. ...
