The herniated disc is one of the common painful diseases in clinical practice. Surgical treatment is required for large herniation and serious condition, but patients with relatively small herniation that cannot reach the surgical standard or refuse to undergo open surgery are mostly treated conservatively in the past, with long treatment period and inaccurate efficacy. The Department of Pain Management has carried out targeted radiofrequency minimally invasive surgery to treat disc herniation, which has achieved very satisfactory clinical results. With the development of technology and medicine, radiofrequency technology has become one of the common means of treating disc herniation in the pain department, and it has developed rapidly and received increasing attention in recent years because of its advantages such as significant efficacy, minimally invasive and less complications. Radiofrequency thermocoagulation target treatment is accurately positioned under the image, and the radiofrequency needle is directly punctured to the herniated area under the precise guidance of the navigation system to denature and coagulate the nucleus pulposus at the herniated area, shrink and reduce the volume, and release the compression. This method does not hurt the normal nucleus pulposus tissue, while repairing the ruptured fibrous ring, inactivating the nerve endings of the nascent lesions in the disc, directly blocking the release of glycoproteins and β-proteins in the nucleus pulposus fluid, and the warming effect plays a good therapeutic role on the injured fibrous ring, edematous nerve roots and inflammatory reactions in the spinal canal, and the symptoms disappear or are reduced immediately after treatment. Compared with the previous minimally invasive treatment methods such as laser vaporization and ozone nucleolysis, this method changes the treatment method with the main purpose of accelerating degeneration into a treatment method with the main purpose of repair, which will not affect the height of the patient’s vertebral space and the stability of the spine after surgery, and greatly reduces the occurrence of postoperative complications. Compared with other treatment methods, target radio frequency has the following advantageous features 1, efficient and safe: the treatment electrode of the special radio frequency instrument for the nervous system is only 0.7mm in diameter, the surgery can be done under local anesthesia, without analgesics, antibiotics, hormones, the treatment is only for the physical change process of the diseased intervertebral disc, without any side effects on the human body, it removes the diseased nucleus pulposus tissue directly without hurting any normal tissue, making the treatment More green, more humane. 2, precise positioning: radiofrequency thermal coagulation target treatment is under the image positioning, monitoring and guidance directly on the lesion of the nucleus pulposus, the data is accurate to less than 1mm, the angular error is less than 1 degree, so that the treatment is more accurate and more effective. 3.Identify the nerve: the nerve system’s precise identification and stimulation function of the special radiofrequency instrument for the nervous system can measure the nerve within 25px of the treatment range and precisely distinguish the motor nerve or sensory nerve, which fundamentally avoids the possibility of mis-injury to the nerve. 4, precise identification of tissue: the equipment has a unique impedance display function, can accurately distinguish the nucleus pulposus fiber ring, calcification points, bone and blood vessels, and accurately display with tone and digital, so that the treatment is more accurate, safe and error-free. 5.Temperature controllable: RF instrument can adjust the temperature arbitrarily, the error is below 2℃, to ensure the safety of treatment, no infection and no heat damage after treatment. 6.Precise calculation: the volume of lesion to be removed is precisely calculated before treatment, and a pre-program is made, that is to say, how much of the nucleus pulposus of the lesion is removed, which makes the treatment more efficient. 7.Fast recovery: you can go down to the ground and start functional exercise of the back muscles after 3 days, and be discharged from the hospital in about a week.
