The laminectomy technique, also known as percutaneous foraminoscopy-assisted lumbar discectomy, is based on the development of percutaneous automated discotomy and aspiration. Under local anesthesia, a lateral posterior lumbar percutaneous puncture is performed, and a 7.5mm surgical channel is placed directly into the intervertebral disc or spinal canal through the intervertebral foramen, and the herniated or prolapsed disc causing pressure is removed under direct endoscopic vision, and the nerve roots are directly released and decompressed; this technique overcomes the shortcomings of traditional surgical methods, and brings the minimally invasive treatment of disc herniation to a whole new level. It is the most minimally invasive, safe and economical technology. The advantages of intervertebral foraminoscopy technology Minimally invasive access to the target area through the lateral approach, avoiding interference with the spinal canal and nerves in traditional posterior surgery, without biting off the vertebral plate, without destroying the paravertebral muscles and ligaments, and without affecting the stability of the spine. Direct resection of the herniated disc, with clear surgical decompression. Wide range of indications Can deal with almost all types of herniated discs, some spinal stenosis, foraminal stenosis, calcification and other bony lesions. The use of special radiofrequency electrodes under the speculum makes fibrous annulus formation and annular nerve branch block feasible to treat discogenic pain. Low complications Low trauma, low chance of thrombosis and infection formation; no postoperative scarring at important posterior structures causing adhesions to the spinal canal and nerves. High safety local anesthesia, which enables intraoperative interaction with the patient without injury to nerves and blood vessels; basically no bleeding, clear surgical field of view, greatly reducing the risk of malpractice; fast recovery the next day after surgery, and an average of 3-6 weeks to resume normal work and physical exercise. High patient satisfaction immediate pain relief, self-care of urine and stool, simple care, oral antibiotics can be taken, skin incision is only 7mm, in line with the aesthetic point of view. Wide range of extension combined with percutaneous fixation technique, fusion and fixation of spinal slippage and instability can be accomplished in a minimally invasive manner; this basic platform can be easily extended to cervical disc endoscopic surgery.
