1, precise positioning: direct hit lesion radiofrequency thermal coagulation target surgery is under the C-arm guidance of precise positioning, direct hit lesion site, directly on the lesion of the nucleus pulposus, without injury to the surrounding tissues and nerves, so that the treatment is more effective and safer. 2, temperature control: rapid thermal coagulation according to the patient’s different tolerance and different lesion sites, radiofrequency instrument can arbitrarily adjust the temperature of thermal coagulation, to ensure rapid thermal coagulation ablation of the nucleus pulposus at the same time, to ensure that the treatment is not infected, no thermal damage, so that the treatment is safer. 3.Identify the nerve: precise tissue RF instrument has the unique function of precise identification of nerve, which can quickly test to the nerve within 1cm of the treatment range to ensure no injury to the nerve tissue; it also has the unique impedance display function to precisely distinguish the tissue to ensure safe and effective treatment. 4.Precise calculation: The precise treatment RF instrument has the function of precise calculation of the volume of the lesion nucleus, so that the volume of the lesion can be calculated precisely before treatment, so that the pre-planning can be made and the lesion nucleus can be thermal coagulated as much as possible, which makes the treatment more precise and effective. 5, ablation of the nucleus pulposus: release the compression of radiofrequency thermal coagulation target surgery through precise positioning, choose the appropriate patient’s own thermal coagulation temperature, rapid denaturation of the lesion nucleus pulposus, coagulation, shrinkage to reduce the volume of the lesion nucleus pulposus, release its compression of the peripheral nerves, crestal pulp. 6.Minimally invasive and painless: the whole treatment is carried out under local anesthesia safely and efficiently, while the puncture needle of RF is only 0,9mm, and the precise positioning of C-arm and controlled ablation temperature make the treatment process safer and more accurate, and the treatment can be recovered quickly and efficiently.
