Embodiment Construction

[0016] The design of a multi-circular tangential stereocoil for deep transcranial magnetic stimulation of the present invention will be further described in detail with reference to the accompanying drawings.

[0017] A multi-circle tangential three-dimensional coil design for deep transcranial magnetic stimulation of the present invention is composed of four coil units. In coil unit I, the inner and outer diameters of the large coil are 60mm and 70mm respectively, and are located inside the large coil. The inner and outer diameters of the five small coils are 10mm and 20mm, respectively. Ⅰ, Ⅱ, and iii coil units use the same coil diameter, and the distance from the scalp is 5-10 mm. The inner and outer diameters of the IV coil unit are 130mm and 140mm. The coil windings in the HCA coil and the multi-circle tangential stereocoil design for deep transcranial magnetic stimulation of the present invention are all made of copper wire, and its cross-sectional area is 25mm 2 , the...

Abstract

The invention relates to a multi-cycle tangential stereoscopic coil used for deep transcranial magnetic stimulation. The multi-cycle tangential stereoscopic coil comprises a first combined coil unit,a second combined coil unit, a third combined coil unit and a circular coil unit, wherein each combined coil unit comprises a large external coil and five same small internal coils which are mutuallytangent, the first combined coil unit is spatially located on the upper portion and is parallel to the circular coil unit, the radius of the circular coil unit is largest, and the other two combined coil units are mutually parallel, perpendicular to the first combined coil unit and are located on the two sides respectively. The current directions of the large external coils in the three combined coil units are identical to the current directions of the small central internal coils but opposite to the current directions of the other four small tangent coils; the current directions of the largeexternal coil of the first combined coil unit and the circular coil unit are clockwise, and the current directions of the large external coils of the second and third combined coil units are anticlockwise and clockwise respectively.

Description

technical field [0001] The invention relates to transcranial magnetic stimulation technology, in particular to a multi-circle tangential three-dimensional coil which can reduce the electric field intensity at the scalp, eyeball and optic nerve while increasing stimulation targets. 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 bioelectric currents to be conducted in tissues, changing the action potential of neurons in the cerebral cortex, and affecting brain metabolism and neuroelectric activity. While deep transcranial magnetic stimulation (dTMS) stimulates cortical nerves, it can also stimulate deep tissues such as the hippocampus and thalamus, which is of great significance to the research on the pathogenic mechanism and treatment methods of various neurological diseases. Since 1985, when Barker and others successfully u...
