Problems solved by technology

Although the traditional "8" shaped coil has a great improvement in stimulation focus and stimulation depth compared with the circular coil, due to the large magnetic field and induced electric field generated on both sides of the coil, it is easy to cause unnecessary damage to non-target tissues. At the same time, since a coil parameter value is fixed in its coil structure, the changing process of the alternating magnetic field generated under the same discharge voltage is basically similar. For a stimulating coil that cannot change the spatial structure at will, it limits Flexibility in different clinical application options

The device realizes flexibility and selectivity of improving the focusing degree of coil stimulation and the stimulation depth, and realizes different stimulation effects of magnetic stimulation.

Description

technical field [0001] The invention relates to the technical field of magnetic stimulation devices, in particular to a magnetic stimulation coil fixing device with a folding structure and adjustable excitation focus depth. Background technique [0002] Magnetic stimulation technology is a new method first proposed by Barker et al. in 1985 to use a circular coil to generate a time-varying magnetic field to stimulate brain nerve tissue, generate an induced current in the tissue, and regulate and interfere with brain function. Ueno et al. subsequently proposed the "8"-shaped stimulation coil, which improved the stimulation focus of the circular coil. [0003] The stimulation mechanism of magnetic stimulation to organisms is realized by using electromagnetic relations. When a time-varying current flows through the magnetic stimulation discharge coil, the discharge coil will generate a time-varying magnetic field. When the biological tissue is in this time-varying magnetic fie...
