With the development of science and technology and medical device innovation, the concept of minimally invasive is gradually gaining popularity, and “intervertebral foraminoscopy” is currently the representative technology of minimally invasive spine technology, which is the most minimally invasive, safe and economical technology; this technology combines percutaneous puncture under fluoroscopy and endoscopic technology, and adopts the “targeting This technique combines fluoroscopic percutaneous puncture and endoscopic technology, and uses “targeted” technology to remove the herniated disc tissue clearly, completely and safely without incision, which is a boon for patients. Introduction of intervertebral foraminoscopy technology For cases of herniated or prolapsed discs, a fluoroscopic puncture is made through the safety triangle into the spinal canal, and the diseased nucleus pulposus is removed microscopically, while intravertebral disc fibrous annuloplasty is done; for cases of spinal stenosis and neural foraminal stenosis, intervertebral foraminal enlargement and shaping are feasible. The advantages of intervertebral foraminoscopy technology: 1, minimally invasive Through the lateral approach to reach the target area, to avoid the traditional posterior surgery on the interference of the spinal canal and nerves, without biting off the vertebral plate, without destroying the paravertebral muscles and ligaments, with little impact on the stability of the spine. 2.The purpose is direct The herniated disc tissue is removed directly under the endoscope, and the surgical effect is reliable; 3.Wide range of indications It can deal with almost all types of disc herniation, part of spinal stenosis, foraminal stenosis, calcification and other bony lesions. Endoscopic use of special radiofrequency electrodes, feasible fiber annuloplasty, treatment of discogenic pain. 4.Low complications Small trauma, low chance of complications such as thrombosis and infection; no scar left at the important posterior structures after surgery, which in turn causes adhesions of the spinal canal and nerves. 5, high safety local anesthesia, intraoperative interaction with the patient, the chance of nerve and vascular injury is very small; less bleeding, clear surgical field of view, greatly reducing the risk of misuse; 6, fast recovery the next day after surgery can be down to the ground, the average of 3-6 weeks to resume normal work and physical exercise. 7.High patient satisfaction Immediate pain relief, self-care of urine and stool, simple care, oral antibiotics can be, feasible outpatient surgery; skin incision is only 7mm, in line with the aesthetic point of view. 8.Wide range of extension Combined with percutaneous fixation technology, the fusion and fixation of spinal slippage and instability can be completed in a minimally invasive way.
