The invention discloses a transcranial magnetic pulse waveform conversion circuit which comprises an input port, an output port and a control signal port, the input port and the control signal port serve as the input of a driving control circuit, the output of the driving control circuit is connected to a direction changing circuit, and the input of the direction changing circuit is connected to the output of the driving control circuit; the direction changing circuit is of an H-bridge structure formed by Q1, Q2, Q3, Q4, Q5, Q6, Q7 and Q8 silicon controlled rectifiers, the direction changing circuit is connected with a half-sine waveform shaping circuit, the direction changing circuit is further connected with a single-phase wave shaping circuit, the H-bridge structure of a plurality of silicon controlled rectifiers is adopted, the types of output magnetic stimulation pulse waveforms are increased, the waveform direction can be changed, and the output magnetic stimulation pulse is more stable. Different types of nerve depolarization can be caused, and different nerve regulation and control functions can be expanded.
Description
technical field [0001] The invention relates to the field of transcranial magnetic pulse waveform control circuits, in particular to a transcranial magnetic pulse waveform conversion circuit. Background technique [0002] Transcranial Magnetic Stimulation (TMS) is a non-invasive technology that acts on the cerebral cortex. It mainly uses the principle of time-varying magnetic field to generate induced current, and applies the pulsed magnetic field to the cerebral cortex to depolarize the cortical neurons. Action potential, a physical neuromodulation technique that affects the electrical activity of the cerebral cortex. After more than 30 years of research and clinical application, transcranial magnetic stimulation has been proven to have a wide range of effects in the treatment of Parkinson's disease, epilepsy and related movement disorders, depression and mood disorders, stroke, schizophrenia and chronic pain. Application prospects. In addition, transcranial magnetic stim...
