Background technique

Deep brain stimulator (DeepBrainStimulation, DBS) regulates abnormal neural circuits by sending out electrical impulses to stimulate brain nerve nuclei. Because of its minimally invasive characteristics, DBS has become a routine surgical method for the treatment of essential tremor, Parkinson's disease, dystonia and other movement disorders. During DBS surgery, the placement and contact effect of the stimulation electrodes will affect the treatment of DBS. The effect has a significant impact.
