I. The latest medical research found that the main cause of lumbar disc herniation is that the nucleus pulposus in the lumbar spine, which was originally in a translucent jelly, gradually loses its original elasticity and toughness with the aging of the body or injury, and becomes granular tissue, in which case if the nucleus pulposus is squeezed or traumatized, it will come out of the fibrous ring that protects it, and the hardened and crusted nucleus pulposus, which is the disc herniation, will The prolapsed nucleus pulposus hardens and crusts, which is a disc herniation and causes sciatica by compressing the sciatic nerve; the prolapsed nucleus pulposus also stimulates the muscle tissue near the lumbar spine, generating inflammation and causing back pain, making the patient suffer from pain. Second, the principle of lumbar spine radiofrequency current catheter ablation for lumbar disc herniation The pain of lower limbs induced by lumbar disc herniation and lumbar spinal stenosis is caused by inflammatory exudation and adhesion of tissues at the exit of nerve roots and repeated stimulation, radiofrequency current catheter ablation can loosen the adhesion of tissues around nerve roots, relieve nerve root edema and loosen adhesions, thus relieving pain. The principle of lumbar spine radiofrequency current catheter ablation: (1) low-temperature radiofrequency: warm radiofrequency inhibits or interrupts nociceptive conduction through tiny vibrations, thus playing the role of pain relief; in addition, it promotes the absorption of inflammatory edema and relieves spasm to achieve the purpose of pain relief; warm conduction causes local vasodilation and enhances cell permeability, which not only facilitates the absorption of inflammation, but also accelerates metabolism and plays the role of anti-inflammatory This not only facilitates the absorption of inflammation, but also accelerates the metabolism of the new body and plays an anti-inflammatory and analgesic role. (2) Catheter pulse: mainly through thermal effect, it causes vasodilation, accelerates blood circulation, accelerates nutrient metabolism of muscle tissues and nerves, improves local tissue ischemia and hypoxia, reduces excitability of sensory nerves and tension of muscle fibers and connective tissues, improves local microcirculation, strengthens tissue nutrition and cell activity, promotes tissue regeneration and formation of bioactive substances, accelerates excretion of pain-causing substances, and interrupts the vicious cycle of pain. The purpose of anti-inflammatory and analgesic is achieved by interrupting the painful cycle. Efficacy evaluation: Lumbar current catheter ablation is a minimally invasive procedure performed in the CT room. From the accurate positioning of the puncture point, the position of the current catheter is repeatedly adjusted under CT until it is satisfactory, and before radiofrequency ablation, diluted photographic agent is injected from the catheter around the nerve root to view the integrity of the dural sac, then lidocaine, Depo-Provera, saline and other drugs are injected from the current catheter, and finally radiofrequency ablation. The procedure takes about 1 hour, which is fast, minimally invasive, reliable, and worthy of clinical promotion. Third, lumbar spine radiofrequency current catheter ablation unique six safety guarantee accurate positioning: lumbar spine radiofrequency current catheter ablation treatment is accurate positioning under CT, CT’s precise guidance directly in the lesion of the nerve root, data accurate to less than 1mm, the angle error is less than 1 degree, improve the accuracy of treatment, almost no injury to any normal tissue. Precise identification and stimulation function: The precise identification and stimulation function of the nervous system unique to RF for the nervous system can measure the nerves within 1mm of the treatment area and distinguish motor nerves or sensory nerves precisely, the accuracy of which can be imagined. Unique nerve root imaging function: After accurate positioning, nerve root imaging is performed, which can distinguish the location of nerve roots and dura mater, ensuring the accuracy and safety of treatment. Controllable temperature: RF instrument can adjust the temperature arbitrarily, the highest temperature is below 42 degrees Celsius, which ensures the safety before and after the treatment, no infection and no heat damage. No damage to normal tissues: The precise calculation function of RF for neurological system can accurately calculate the temperature and frequency of RF before treatment, without hurting any normal tissues, which makes the treatment more humane and effective. Whether it is laser, spinal canaloscopy, fiber ring repair, ozone or collagenase injection, percutaneous excision and suction, the good nucleus pulposus is removed and the diseased part is allowed to retract. Humanized treatment: The whole treatment process of the neurological special RF instrument uses local anesthetics and does not use analgesics or antibiotics, which has no side effects on the human body, making the treatment greener and more humanized. At the same time, it has changed the history of intervertebral disc treatment, changing the treatment method with the main purpose of speeding up degeneration to the treatment method with the main purpose of repair. The six safety measures of lumbar spine radiofrequency current catheter ablation are incomparable to any minimally invasive devices and methods. This therapy gradually replaced the previous treatment method whose main purpose was to accelerate disc degeneration, and it has epoch-making significance in the history of minimally invasive spine treatment.
