摘要

Transcupoint magnetic stimulation technology is a new acupuncture point treatment intervention technology. However, the stimulation coil of the traditional transcranial magnetic stimulation instrument can't meet the needs of high focus of acupuncture point stimulation. Therefore, this paper proposes a comprehensive consideration of the stimulation effect and Joule heat loss of the percussion stimulation coil optimization design method, which could enhance the focus of the local space of the figure-of-eight (FOE) coil and reduce the heat of the coil. Based on the finite element method, the induced electric field generated by the point stimulation coil is obtained, and the stimulation effect evaluation model and the coil comprehensive evaluation model are constructed. Finally, a parametric sweep based on the above model obtains the lowest power coil. The simulation results verify the superiority of the proposed design
