Problems solved by technology

However, in the existing controlled experiments on the curative effect of transcranial magnetic stimulation, the relative position of the stimulation coil is changed, for example, the posture of the figure-eight coil is changed by 90 degrees to weaken the stimulation intensity of the coil to the experimental subjects.
However, such controlled experiments cannot achieve the double-blind effect

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the embodiments of the specification and the accompanying drawings.

[0018] The principle of a transcranial magnetic stimulation system is given here, such as figure 1 As shown, the transcranial magnetic stimulation system generally stores energy in the energy storage pulse capacitor through the power supply, and then lets the energy storage pulse capacitor quickly discharge the coil with a large current to generate an instantaneous pulse magnetic field to stimulate the patient. Generally, the stimulation coil uses 8 When the figure-shaped coil and the 8-shaped coil are normally stimulated, the current at the intersection of the coils flows in the same direction, so that the maximum value of the magnetic field appears at the intersection of the two circular coils, which is used to stimulate the patient.

[0019] The basic principle of the figure-of-eight coil used in the control experiment of tra...

Abstract

The invention provides an 8-shaped coil for a transcranial magnetic stimulation contrast experiment. The coil comprises a first circular coil body and a second circular coil body, the first circular coil body is wound anticlockwise, the input end is A2, and the output end is A1; the second circular coil is wound clockwise, the input end is B1, and the output end is B2; the input ends and the output ends of the two circular coils are connected and combined through four single switches K1, K2, K3 and K4 to form different configuration states that the current directions at the intersections of the two circular coil bodies are the same or opposite; the on-off states of the single switches K1, K2, K3 and K4 are controlled through a control module. The invention further provides a configurationmanagement method of the 8-shaped coil. The 8-shaped coil is configured by controlling the on-off states of the single switches K1, K2, K3 and K4, and normal stimulation or pseudo-stimulation is freely realized. When the contrast experiment is carried out, a double-blind effect can be achieved on an operator and an experimenter.

Description

technical field [0001] The invention belongs to the technical field of transcranial magnetic stimulation, and in particular relates to a figure-eight coil used in a transcranial magnetic stimulation control experiment and a configuration management method thereof. Background technique [0002] Transcranial magnetic stimulation (TMS) technology is a technology that uses pulsed magnetic fields to act on the central nervous system to change the membrane potential of cortical nerve cells, causing them to generate induced currents, affecting brain metabolism and neuroelectric activity, thereby causing Magnetic stimulation technology for a series of physiological and biochemical reactions. TMS is noninvasive, painless and safe, and can be used to stimulate cranial nerves, nerve roots and peripheral nerves. At present, it is widely used in the diagnosis and treatment of neuroscience, brain science research and clinical diseases. [0003] When judging the efficacy of the transcran...
