Ox horn-like transcranial magnetic stimulation coil capable of increasing magnetic field depth

Abstract

The present invention discloses an ox horn-like transcranial magnetic stimulation coil capable of increasing the magnetic field depth. The coil comprises a coil body; the coil body is in an arc horn shape formed by a lead wire in a surrounding manner; the coil body continuously forms an arc shape; openings in the two ends of the coil body are opposite; the whole coil body forms an ox horn-like structure in a surrounding manner; the distance between central points of the cross sections of the two ends of the coil body is 5-20 cm; the inner diameters of the openings in two ends of the coil bodyare both 1-25 cm; and a vertical axial included angle between the cross sections of the two ends of the coil body is 0-180 DEG C. By arranging the ox horn-like coil, a magnetic line of force can be constrained and self-guided; and compared with an existing transcranial magnetic stimulation coil, the ox horn-like transcranial magnetic stimulation coil can achieve the effects of highly centralizingmagnetic stimulation, increasing the depth of magnetic stimulation and improving the utilization rate of a magnetic field, and also can achieve the effect of improving the biological effect.

Description

Technical field [0001] The invention belongs to the field of transcranial magnetic stimulation treatment equipment, and is specifically a horn-like transcranial magnetic stimulation coil that increases the depth of the magnetic field. Background technique [0002] Transcranial magnetic stimulation (TMS) was founded by Barker in 1985. Based on the principle of electromagnetic induction and electromagnetic conversion, the magnetic field generated by the transient current of the stimulation coil penetrates the skull to generate induced current to stimulate neurons to trigger a series of physiological and biochemical reactions. Non-invasive stimulation technology, TMS acts on the human brain to cause changes in neural activity, and can detect changes in motor evoked potentials, changes in brain electrical activity, cerebral blood flow, metabolism, and brain function. Its microscopic effects include changes in cell membrane potentials, action potentials, neurotransmitters, receptors, ...

AI Technical Summary

Problems solved by technology

[0006] Transcranial magnetic stimulation therapy has the characteristics of non-invasive, non-invasive, mild side effects, and wide clinical indications, so more and more attention has been paid to it. However, there are various forms of transcranial magnetic stimulation, such as: single coil, 8-shaped coil, SLINKY coils, angled 8-shaped coils, and H-shaped coils, but most of them have insufficient stimulation depth and unsatisfactory positioning, which affects the therapeutic effect

[0007] Therefore, the design of the coil is the key to the study of transcranial magnetic stimulation therapy. However, most of the existing coils for transcranial magnetic stimulation therapy cannot constrain and self-guid the magnetic lines of force, and at the same time cannot achieve high concentration of magnetic stimulation, increase the depth of magnetic stimulation, The effect of improving the utilization rate of the magnetic field, but also unable to achieve the effect of improving the biological effect
