The invention provides an 8-shaped coil
transcranial magnetic stimulation system based on a
magnetic resonant coupling principle. A first stimulation coil and a second stimulation coil of the
system are externally tangent to each other. The inner
diameter of each of the first stimulation coil and the second stimulation coil is 56mm, and the outer
diameter of each of the first stimulation coil and the second stimulation coil is 62mm. A first source coil is internally tangent to the first stimulation coil, and a
second source coil is internally tangent to the second stimulation coil. The two internally-tangent points are superposed with the externally-tangent point between the first stimulation coil and the second stimulation coil. The inner
diameter of the first source coil and the inner diameter of the
second source coil are 30mm, and the outer diameter of the first source coil and the inner diameter of the
second source coil are 36mm. The discharging current directions of the middle points of the central connecting lines of the two coil units are consistent, and the middle points are corresponding to the target position
simulation points. The 8-shaped coil
transcranial magnetic stimulation system is advantageous in that when the system source coil is provided with the current having the same intensity, the stimulation intensity of the affected parts having the same depth in the cranium can be increased; the
utilization rate of the energy transmitted from the source coils to the cranium model can be increased by more than three times; when the energy utilization efficiency is increased and the
excitation current strength is reduced, the stimulation intensity can be increased, and the stimulation accuracy of the target positions can be increased.
