Parkinson’s disease surgery, i.e. brain pacemaker surgery, is not prone to recurrence after surgery. The advantage of brain pacemaker for Parkinson’s disease is that it can be adjusted. The cause of Parkinson’s disease is the abnormal apoptosis of dopamine neurons, and with the prolongation of time, the apoptotic cells will become more and more, and therefore the symptoms will progress gradually. After the implantation of brain pacemaker in brain pacemaker surgery, the parameters can be adjusted regularly, because the brain pacemaker is set up with three parameters, which have to be adjusted for the comprehensive adjustment of the tremor, muscle straightness, and the abnormality of the gait in Parkinson’s disease, respectively. Once the tremor reappears after 3 months or half a year or the muscle tone is more pronounced than before, the patient can go to the hospital to have the pacemaker upgraded and the parameters adjusted. After the parameters are adjusted, the symptoms of Parkinson’s disease patients will be improved again. Therefore, the neuromodulation surgery of the brain pacemaker can improve the quality of life of the patient, and can be adjusted when the patient’s symptoms recur, so that the patient can achieve a better therapeutic effect.
