An intervertebral foramoscope is a type of spinal endoscope that includes a tube equipped with a light, along with the corresponding supporting minimally invasive spinal surgical instruments, imaging and image processing system, and dual-frequency radiofrequency machine, together forming a minimally invasive spinal surgical system. It enters the intervertebral foramen from the side or side and back of the patient’s body and operates outside the disc fibrous annulus, where the herniated nucleus pulposus, nerve roots, dural sac and hyperplastic bone tissue can be clearly seen under direct endoscopic vision. Then, various types of grasping forceps are used to remove the herniated tissue, microscopic debridement of bone, and radiofrequency electrodes to repair the broken fibrous annulus. It is the least traumatic and most effective minimally invasive treatment for herniated discs of its kind. The principle of intervertebral foraminoscopic minimally invasive disc removal is also the decompression of nerve roots, which can be commonly understood as “removing the stone that compresses the nerve” to relieve symptoms. Suitable people include: 1, various types of lumbar disc herniation 2, keyboard nucleus pulposus prolapse or free 3, open surgery failure 4, intervertebral foraminal stenosis 5, calcified lesions 6, discogenic back pain. The characteristics of this technology are: 1, minimally invasive high safety: clear surgical field of view, no need to destroy the paravertebral muscles, ligaments, no need to bite off the vertebral plate, the stability of the spine is not affected. 2.Precise positioning with direct purpose: microscopic targeted positioning puncture technology, accurate removal of the herniated nucleus pulposus, the exact surgical effect. 3, local postoperative pain-free: the surgery is completed under local anesthesia, which can interact with the patient and greatly reduce the risk of misoperation; immediate postoperative pain relief, high patient satisfaction. 4, very small trauma, not easy to bleed: the surgical incision is only 7 mm, basically no bleeding, no postoperative scar growth, causing nerve adhesions. 5, not easy to recur: the success rate of surgery is about 93%, and the recurrence rate is less than 4%, the success rate of treatment of recurrent disc herniation is more than 85%. 6, rapid recovery: short surgery time; fast recovery, the next day after surgery can be down to the ground activities, an average of 3-6 weeks to resume normal work and physical exercise.
