Lumbar disc herniation is a common clinical spine disease, in addition to surgery and conservative treatment, minimally invasive interventions such as PLDD, percutaneous aspiration, spinal canaloscopy, and collagenase, of which radiofrequency thermocoagulation is a safer method. Minimally invasive treatment of disc herniation such as percutaneous excision and suction, PLDD, all indirectly achieve the purpose of treatment by removing part of the middle nucleus pulposus of the disc to decompress the periphery of the disc, but the normal nucleus pulposus is destroyed while treating the disease, and it is difficult to selectively treat the deformed herniated nucleus pulposus, and the damaged annulus fibrosus, and it is also impossible to directly block the spillage of the nucleus pulposus fluid, and a series of bleeding, infection, nerve damage, gap narrowing, etc. Complications cannot be evaluated. Radiofrequency thermal coagulation target treatment is to directly denature, coagulate, shrink, reduce the volume of the nucleus pulposus in the protruding pathogenic part and release the compression without injuring the normal nucleus pulposus tissue, while directly blocking the release of glycoprotein and beta protein in the nucleus pulposus fluid, and the warming effect plays a good therapeutic role on the injured fibrous ring, nerve root edema, and inflammatory reaction in the spinal canal, and the symptoms disappear and reduce immediately after treatment, which is effective and safe. The puncture needle for radiofrequency is only 0.7mm thick, the patient’s pain is minimal during puncture, the operation is safe, the nerve monitoring function and the controllability of time and temperature will not cause heat damage to the nerve root, the display of impedance can determine the nature of the tissue being treated, the temperature of 85-90℃ itself has a hemostatic effect, and the minimal trauma and high temperature make the chance of infection very low. Radiofrequency targeted therapy for herniated disc is a new minimally invasive treatment method that is highly efficient, safe, simple to operate and less costly. It is a qualitative leap forward in minimally invasive treatment of herniated discs. What is radiofrequency thermocoagulation? It is a high frequency radiofrequency current emitted through a magnetic field, and the radiofrequency current generates a changing magnetic field at the tip of the working electrode, which causes molecular movement and frictional heat generation in the target tissue covered by the magnetic field, and thermal coagulation destroys the tissue in the target area. It is dedicated to nerve stimulation for pain transmission path blocking and flexural destruction. It is an international advanced minimally invasive technology and the world’s leading-edge pain treatment method, with the characteristics of minimally invasive, qualitative, quantitative, precise efficacy and less complications. 1.Acoustic impedance monitoring system: the needle tip enters different tissues of the body, and the different tone prompts and digital display ensure the direction of needle entry and macro safety. 2.Precise identification and stimulation function of sensory-motor nerve ensure the safety of treatment. 3, the artificial controllability of thermal coagulation temperature and time can ensure the accuracy and safety of destruction. Six major safety measures of radiofrequency thermal coagulation target treatment of disc herniation: 1. accurate positioning of large C-arm X-ray machine, real-time monitoring under digital subtraction, accurate data measurement to 0.1cm. 2. Precise identification and stimulation function of the nerve. Can measure the nerve within 1cm of the treatment range and accurately distinguish whether it is a motor nerve or a sensory nerve. 3.Impedance measurement display function. Can accurately distinguish what tissue is the location of the needle tip, its impedance how much, in short: can distinguish the nucleus pulposus, fiber ring, calcification point, bone and blood vessels and accurate display with tone and digital. 4, the controllability of the temperature. Arbitrary adjustment of temperature, the error is below 2 degrees Celsius, to ensure the safety of the treatment. 5.Precise calculation of treatment range volume. The volume of the treated tissue can be precisely calculated according to the length of the working end, that is to say, how many medullary nuclei can be removed if you want. 6, the whole process of treatment without local anesthetics, analgesics, antibiotics, hormones, only a physical change process, without any side effects on the human body. These six safety measures are not available in any of the minimally invasive treatment devices and methods for intervertebral discs in the world at present.
