The purpose of the minimally invasive intervertebral foraminoscopic spine technique is to operate outside the annulus fibrosus of the intervertebral disc to completely remove the protruding or prolapsed nucleus pulposus and hyperplastic bone in order to relieve the pressure on the nerve roots to eliminate the pain due to the pressure on the nerves. The surgery is performed under local anesthesia, and there is no need to fast or drink before the surgery. During the surgery, the patient is conscious and can communicate with the surgeon about his or her feelings during the surgery. In addition, the intervertebral foraminoscopy system enters from one side of the lumbar vertebrae, utilizing the natural channels of the human skeletal structure, so there is no need to remove bones and ligaments, and there is no damage or destruction of the stabilizing structure of the patient’s lumbar vertebrae. 1, the whole operation is completed under local anesthesia, the patient is awake throughout, avoiding the risk of anesthesia, can interact with the patient during the operation, without injuring the nerves and blood vessels; basically no bleeding, clear surgical vision, greatly reducing the risk of misuse; skin incision of about 1cm or so, minimal trauma; 2, can deal with almost all types of herniated intervertebral discs, some of the spinal stenosis, spinal foraminal stenosis, calcification and other osseous lesions, with a wide range of indications; 3.No removal of the vertebral plate, no destruction of paravertebral muscles and ligaments, less interference with the nerves and intravertebral structures, preservation of the epidural fat, reducing intraoperative bleeding and postoperative formation of intravertebral scar tissue, and reducing the likelihood of postoperative scar adhesion and vertebral instability; 4.Surgical time is short, postoperative recovery is fast, quick recovery, you can go down to the ground on the next day after the operation, and on average, it takes 3-6 weeks to Resumption of normal work and physical exercise, shortening the hospitalization time; 5. Avoiding the recurrence of symptoms caused by tissue adhesion after traditional open internal fixation, combining with percutaneous fixation technology, it can minimally invasive way to complete the fusion and fixation of spondylolisthesis and instability, with a wide range of expansion; 6. Compared with the traditional open surgery, the effectiveness rate is comparable to or higher, and the risk of reopening and complications of the patients who have poor results of the traditional open surgery are significantly higher 7. Immediate postoperative pain relief, self-management of urine and feces, simple nursing care, and high patient satisfaction.
