Disc herniation is a series of symptoms caused by disc degeneration, herniated nucleus pulposus irritation and compression of nerve roots and spinal blood vessels, and there are more than a dozen treatment methods. Among them is the minimally invasive intervertebral foraminoscopy technique, which is a new treatment for herniated discs. The treatment is carried out under C-arm guidance, in which the apparatus is placed into the diseased tissue with minimal trauma, and the disc is removed, so that the volume of the disc is rapidly and effectively reduced, the pressure in the disc is reduced, or the herniated nucleus pulposus is partially “retracted and returned”, or the herniated material is ablated and atrophied, so that the compression on the spinal cord or nerve roots is relieved. To achieve the purpose of treatment. The advanced intervertebral foraminoscopy technology introduced by our hospital from Germany is an “outside-in” technology. Using the foraminoscope and accompanying surgical instruments, the foramen is entered from the side or rear of the patient’s body (either flat or oblique) and the procedure is performed in the safe working triangle. By performing the surgery outside the disc fibrous ring, the herniated nucleus pulposus, nerve roots, dural sac and hyperplastic bone tissue can be clearly seen under direct endoscopic vision. Its working trocar is placed in the epidural cavity, inferior to the nerve root, so that damage to the nerve root and dural sac can be avoided. After removing the protruding nucleus pulposus tissue, the residual tissue is vaporized using the Trigger-Flex bipolar technique with controlled length and bending angle dedicated to the dual-frequency radiofrequency machine; the broken fibrous ring is closed using the principle of local heat contraction; if there is bleeding, the bipolar can also be used to stop the bleeding. The procedure is performed under local anesthesia, and throughout the procedure, the patient is in a completely awake state, and the surgeon and patient can communicate with each other. The procedure can be performed in the lateral or prone position. The procedure is simple and can be done in an outpatient operating room. The entire procedure can take less than an hour and the patient can be discharged the same day after surgery. Removal of the disc, repair of the annulus fibrosus, removal of osteophytes, enlargement of the intervertebral foramen, and modification of the end plate can be performed simultaneously. Minimally invasive intervertebral foraminoscopy is a visual direct decompression technique that is safer, has a wider range of indications, is more minimally invasive, causes less damage, is more effective and has a faster recovery than other current minimally invasive spine techniques. It is possible to perform surgery on all segments from the cervical spine to the lumbar 5 sacral 1. The cervical spine and lumbar 5-sacral 1 surgery has unique advantages.
