Deep brain electrical stimulation, also known as brain pacemaker, sends electrical pulses to the relevant nerve nuclei controlling movement through the electrodes implanted in the brain to regulate abnormal neuroelectrical activities, so as to achieve the purpose of treating diseases. Deep brain stimulation is the most widely used in Parkinson’s disease and is now spreading to other application fields. For example, in addition to the treatment of Parkinson’s disease, it can also be used in the treatment of idiopathic tremor, dystonia, mental and psychological diseases, cognitive disorders, epilepsy, consciousness disorders, etc. deep brain stimulation can be tried. Deep brain electrical stimulation in the treatment of Parkinson’s disease has the characteristics of reversible, adjustable, safe and minimally invasive. It can significantly improve the symptoms of motor retardation, dyskinesia, muscle stiffness and tremor in patients with Parkinson’s disease, reduce the dosage of drugs, reduce the side effects of drugs, improve the quality of life and enable patients to return to work.
Deep brain stimulation is a minimally invasive and safe operation, and the whole process takes about 3-6 hours. Surgical treatment is feasible after the patient is diagnosed and the surgical indications are clear. Firstly, the patient was anesthetized locally, and a titanium alloy frame was installed on the patient’s head. Through CT scanning or nuclear magnetic positioning, the forehead was drilled, and the two electrodes were implanted into the patient’s brain for electrophysiological records. If it was determined that the implantation position was good, the remaining electrodes were placed into the patient’s brain, and some electrical stimulation was given to observe the patient’s response. At the same time, the battery should be implanted into the patient’s chest wall under general anesthesia.
