Pre-operative X-ray localization, identification of the surgical segment and puncture point surgical area marking, sterilization. The drawn circle site is the surgical puncture point. Ni Bing of the Department of Functional Neurosurgery, Xuanwu Hospital, Capital Medical University, laid a sterile surgical sheet to puncture and then expanded the incision to 0.8 cm and placed the surgical working channel. The endoscope was placed and the herniated disc tissue was grasped with a nucleus pulposus under direct vision. The display of the endoscope removes the herniated disc tissue The herniated disc tissue removed is a common condition and most can be relieved with conservative treatment. A few patients have a history of more than three months, conservative treatment is ineffective, or conservative treatment is effective, but frequent recurrence and heavy pain; severe pain, especially leg pain is obvious, affecting sleep and fidgeting, some patients have urinary and fecal disorders and perineal perineal sensation abnormal performance; severe muscle atrophy and muscle strength loss in the lower limbs; these patients need timely surgical treatment. Surgical treatment includes traditional open surgery and the latest endoscopic disc herniation removal. Traditional surgery: partial laminectomy through a posterior lumbar back incision, partial laminectomy and synovectomy, or disc removal through the lamina space. For central disc herniation, an epidural or intradural discectomy is performed after laminectomy. In cases of combined lumbar instability and lumbar spinal stenosis, simultaneous spinal fusion is required. In recent years, minimally invasive surgical techniques such as disc removal under discoscopy and disc herniation removal under percutaneous foraminoscopy have significantly reduced the surgical injury, with a minimum incision of about 0.8 cm, and the effect is comparable to that of open surgery, achieving good results, especially for patients whose general status is not suitable for general anesthesia.
