Cervical spondylosis, lumbar disc herniation and spinal stenosis are common and frequent clinical diseases. The main symptoms are inability to stand upright, headache, vertigo, blurred vision, memory loss, neck and shoulder pain, loss of appetite, regurgitation, vomiting, limb numbness, pain, and weakness of lower limbs, which may lead to paralysis in severe cases. With the development of society, the progress of the times and the increasing intensity of work, spine-related diseases are on a rapid rise year by year, while the age of onset is on a downward trend. The age of onset is decreasing. From the beginning of the disease in young and middle-aged people, the disease is gradually developing in adolescents over 15 years old. According to the relevant institutions, the current incidence of adolescents accounted for 20-25%, more than 20 years old accounted for more than 30%, more than 30 years old accounted for 35%, more than 40 years old accounted for 45-50%, while more than 50 years old accounted for 60-75%, more than 70 years old accounted for 85%, thus spine-related diseases are an important factor endangering human health. Traditional treatment methods mainly use traction, closure, needle and knife release, fixed braking, manipulation and massage, physiotherapy and other non-surgical and open surgical treatment, which plays an important role in relieving patients’ pain. However, with the overall quality of the nation and the continuous improvement of living standards, the above-mentioned means of treatment to the patient’s disadvantages are no longer accepted by the people, people also have newer requirements for the technical level of clinical treatment of spinal diseases: fast treatment process, less pain, less trauma, does not affect the aesthetics, postoperative clinical symptoms of functional recovery, long-term treatment effect is good recurrence rate is low; the emergence of these requirements, a strong impetus to The rapid development of clinical treatment means for spinal diseases has forced the treatment of spinal diseases into a whole new field —– minimally invasive era of spinal treatment. Traditional minimally invasive techniques include: collagenase lysis, percutaneous excision and suction, laser vaporization (PLDD), plasma nucleus pulposus, radiofrequency ablation, ozone ablation and other therapeutic means came into being, but these methods are also minimally invasive techniques currently carried out in most hospitals, all of which are indirect decompression, with the inability to directly remove the diseased nucleus pulposus, especially the tissue compressing the nerve, the inability to repair the broken fiber ring, the necrotic tissue needs to rely on The effect is not good because of the defects such as natural absorption by human body. Traditional posterior discoscopic (MED) surgery is more reliable than simple ablation, but because the surgical approach and treatment process are consistent with small incision open surgery, it is necessary to implement the lamina opening, stripping muscle and ligament, interference with the spinal canal, pulling the nerve; easy to cause intraoperative bleeding, interference with the field of vision and increased risk, high complications; not applicable to the treatment of extreme lateral herniation, nerve root canal stenosis and discogenic pain (narrow indications); postoperative scar tissue tends to cause adhesions of the spinal canal and nerves, and the treatment effect is not satisfactory. This is also the reason why doctors and patients have difficulty in accepting and trusting minimally invasive techniques, and thus cannot be promoted for many years. So how to solve the above problems and meet patients’ requirements for medical treatment? The emergence of the new intervertebral foraminoscopy technology has brought the treatment of disc herniation into a substantial minimally invasive era, and in 2002, Professor Hoogland (former President of European Minimally Invasive Science) of Germany, after thousands of cases of TESSYS intervertebral foraminoscopy technology, proposed a revolutionary improvement and upgrade technology based on YESS technology – THESSYS technology. THESSYS technology, using natural channels, uses special reaming drills and instruments to enlarge the intervertebral foramen step by step, and can directly and accurately remove the protruding disc tissue under the surveillance of TV screen, and the adjustable multi-angle bipolar radiofrequency electrode can directly ablate the nucleus pulposus, repair the ruptured fibrous ring without heat, and completely release the liquid nucleus pulposus overflow. edema and sterile inflammation, and effectively prevents postoperative disc infection; thus completely solving clinical symptoms and satisfying patients’ needs, pushing the minimally invasive treatment technology for spinal diseases to an unprecedented pinnacle. It makes intervertebral foraminoscopy technology mature. Minimally invasive is a concept, a philosophical idea, and at the same time, a real clinical application technology. It is inextricably linked to the development of imaging, electronics, optics, biomaterials and new instruments. The rapid evolution of recent years is increasingly revolutionizing the philosophy and approach to spinal surgery. Both the early percutaneous puncture interventions and the progressive development of percutaneous fixation, followed by microendoscopic techniques, have demonstrated the importance, and sometimes the decisive factor, of new materials and instruments in minimally invasive surgery. Minimally invasive intervertebral foramoscopic spine technology is a leading international high technology and an important direction for the future development of minimally invasive spine surgery. This technique is the most minimally invasive way to treat herniated discs, avoiding the traditional surgery of stripping the paravertebral muscles, biting off the lamina and ligaments, and destroying the stability of the spine, without disturbing the spinal canal, without pulling the nerve roots, without fusing the spine, preserving the motion segments of the spine, safe and reliable, and more in line with the physiological requirements of spinal motion. The herniated disc tissue and the compressed dural sac and nerves can be clearly displayed during surgery, and the nerve compression tissue can be removed under direct vision, which is safe, effective, and quick to recover, and the patient can get out of bed after surgery. Intervertebral foraminoscopy, rather than traditional discoscopy and simple ablation (including laser, radiofrequency, ozone ablation, etc.), can relieve the pain of most patients with herniated discs and nerve root canal stenosis as a result of medical development, improved instrumentation, and improved medical technology. Although intervertebral foraminoscopy technology has been able to treat most of the disc herniation, due to the influence of traditional minimally invasive technology defects and most doctors’ understanding of minimally invasive technology still stay at the stage of discoscopy technology and simple ablation, so many patients who consult about disc herniation do not get proper treatment guidance, but choose to undergo major open surgery and internal fixation, which brings a lot of inconvenience and regret. Furthermore, many hospitals that currently advertise minimally invasive spine technology basically perform simple ablation (including laser, radiofrequency, ozone ablation, etc.) and discoscopic surgery, which cannot directly decompress or require laminectomy, and their treatment is ineffective or has serious complications, which are also known for traditional minimally invasive surgery. However, the current real minimally invasive decompression technology is intervertebral foraminoscopy technology, which solves the problems that cannot be solved by traditional minimally invasive surgery with satisfactory results. However, the minimally invasive intervertebral foramoscopic technology with reliable results is not accepted by doctors and patients due to the insufficient update of new technology and new knowledge. Of course, minimally invasive treatment is not a panacea, but most herniated discs can be treated minimally invasively by foraminoscopic technology. I believe that with the development of medicine, improvement of medical equipment and medical technology and surgical skills, minimally invasive technology will definitely solve most of the disease problems, not just herniated discs —- The historical trend is unstoppable. Intervertebral foraminoscopy, also known as modern “lock hole surgery”, is the most minimally invasive, safest and most economical technology available. The technical advantages are as follows: 1. Minimally invasive access to the target area through the intervertebral foramen, 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. 2.Directly remove the protruding disc tissue directly, and the surgical decompression is clear. 3, wide indications can deal with almost all types of disc herniation, part of the spinal canal stenosis, foraminal stenosis, calcification and other bony lesions. The use of special radiofrequency electrodes under the speculum, feasible fiber annulus formation and annular nerve branch blocking, treatment of discogenic pain. 4.Low complicationsLow trauma, low chance of forming thrombosis and infection; no scar left at the posterior important structures after surgery, causing adhesions of the spinal canal and nerves. 5.High safety local anesthesia, interactive communication with the patient during surgery, no injury to nerves and blood vessels; basically no bleeding, clear surgical field of vision, greatly reducing the risk of misoperation; 6.Fast recovery the next day after surgery can be down to the ground, an average of 3-6 weeks to resume normal work and physical exercise. 7, high patient satisfaction immediate pain relief, urinary and faecal self-care, simple care, oral antibiotics can be, the skin incision is only 7mm, in line with the aesthetic point of view. 8, a wide range of extension combined with percutaneous fixation technology, available minimally invasive way to complete the fusion and fixation of spinal slippage and instability. Contraindications: 1. If it is believed that the intraspinal compression may be due to benign or malignant tumors, open laminectomy or laminectomy access surgery must be selected. Patients with combined cauda equina syndrome require a posterior median approach for laminectomy and removal of herniated disc tissue, including the nucleus pulposus and annulus fibrosus. 3. For patients with severe lumbar spinal stenosis, open surgery is preferable. However, the specific situation can be determined after specific analysis.
