Most of the patients are delayed until they can no longer tolerate it, and they usually have torn fibrous rings, prolapsed or even free nuclei, and adhesions to the nerve. Ablation does not relieve the nerve compression at all, not to mention the fact that many patients have a combination of osteophytes and stenosis. Therefore, it is difficult for orthopedic surgeons to accept this uncertain treatment concept. 1. Theoretically, it is hoped that the electrode will act directly on the protruding part of the compressed nerve, but in practice it is very difficult to do so because of the invisibility. 2.Patients in need of treatment are those who are not cured, and most of the protruding nucleus pulposus is adhered to the surrounding tissues. Even if the protruding part is destroyed by the electrode and the volume is reduced, most of the patients are not able to lift the compression on the nerve, and the symptoms can not be relieved. 3, the protruding material is not directly removed, the scope and extent of the therapeutic effect is unpredictable. 4.The destroyed tissues are slowly absorbed by the body, and there is a long recovery period after the operation. Dissolution, vaporization, destruction, thermal coagulation and other interventional means, the commonality lies in the indirect decompression achieved only by the reduction of pressure in the disk, the target is blind, the scope is not controllable, and the degree of treatment is not objectively evaluated. The residual tissues are not removed from the body and need to be absorbed by the body naturally, and the postoperative recovery period is long. Minimally invasive surgical treatment: 1. The most minimally invasive surgical treatment, local anesthesia, direct surgical goal, complete decompression; can be extended to the treatment of bony structures and the implantation of built-in materials. 2, through the intervertebral foraminal approach, rather than the traditional surgery of the posterior approach, can observe the nerve and spinal canal but will not cause interference. There is no need to strip the muscles and ligaments during the operation, and there is no need to bite off the vertebral plate, so the stability of the spinal column is not damaged; after the operation, no scar tissue will be formed to cause neural adhesion, and the sequelae and complications are extremely low. 3, the technology is currently in a period of rapid promotion, more and more medical institutions to adopt. 4.The development direction is to combine new materials to complete the artificial nucleus pulposus and artificial disc replacement, with percutaneous technology for fusion and internal fixation. 5, the equipment used not only to complete minimally invasive surgery, but also take into account part of the needs of the pain treatment field. For example, the radiofrequency machine used in this system can do “radiofrequency ablation”, i.e., IDET, which is mainly used for nerve destruction of discogenic pain, in parallel with fibroplasty, and, if necessary, can also be done to ablate the nucleus pulposus within the intervertebral disc; there are 1 or 2 mm electrodes that can be used for cervical spinal spine ablation and part of the target point ablation. The minimally invasive approach has a direct purpose and the lesion is removed completely. Complete decompression of the nerve root under direct vision is the important reference standard for the end of the operation. Continuous irrigation during the operation can take the pain-causing chemical medium out of the body, which is minimally invasive, safe and has definite long-term efficacy.
