RF generator through the needle electrode continuous radiation of the current, in the temperature difference between the electrode to produce a beam of high-frequency through a certain impedance of the tissue, so that the ions in the tissue under the action of high-frequency current vibration, and the surrounding mass friction and generate heat, cut the tissue and make it coagulate. Adjusting the amount of RF output power causes the tissue at the needle electrode to reach the desired temperature and form a certain range of tissue coagulation foci, thus affecting the transmission of nociceptive signals and preventing the onset of pain. If the principle of percutaneous disc nucleus pulposus target point thermocoagulation selects a reasonable puncture path so that the radiofrequency puncture needle (electrode) reaches the target site of the herniated nucleus pulposus of the vertebral disc, and confirms the safe distance between the electrode and the spinal cord, spinal nerve after the strict neurophysiological program test that comes with the neuro RF instrument. The radiofrequency instrument starts working and generates sufficient thermal coagulation treatment temperature in the target tissue (target point). When the temperature of the working end of the RF electrode reaches 60℃ or more, the nucleus pulposus at the protruding site is contracted, the relative position of the nucleus pulposus and the compressed nerve root is changed, the tension of the nerve root is reduced, and the old compression is released. At the same time, the thermal effect may also change the internal environment of the herniated area, directly block the release of glycoprotein and 15 protein in the nucleus pulposus, inhibit the release of local inflammatory mediators, and the therapeutic effect of warmth on the edema of the injured nerve root of the annulus fibrosus and the inflammatory reaction in the spinal canal, so as to achieve the effect of decompression and anti-inflammatory pain relief. Radio frequency thermal coagulation target technology six security measures Radio frequency thermal coagulation target puncture technology has six security measures, completely solved the patients and doctors most concerned about medical safety and healing effect 1, efficient and safe The treatment electrode of the special radio frequency instrument for the nervous system is only 0.7mm, like an acupuncture needle, the whole treatment without numbing drugs, analgesics, antibiotics, hormones, only a physical change process, no side effects on the human body It removes the diseased nucleus pulposus directly without hurting any normal tissue, making the treatment greener and more humane. 2.Precise positioning Radiofrequency thermal coagulation target treatment is under the precise guidance of DSA or CT navigation system 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 effective. 3.Identify the nerve The precise identification and stimulation function of the nerve system that is unique to the neurological system of the special RF instrument can measure the nerve within 1cm of the treatment range and distinguish the motor nerve or sensory nerve precisely, which means that it is impossible to damage the patient’s nerve when you want to treat. Even if you are not a doctor, there is no accident. 4.Precise identification of tissues The impedance display function unique to this device can accurately distinguish the medullary nucleus fiber ring, calcification points, bone and blood vessels, and accurately display them with tones and numbers to make the treatment more accurate and safe. 5.Temperature controllable The RF instrument can adjust the temperature arbitrarily with the error below 2 degrees Celsius to ensure the safety of the treatment and no infection and heat damage after the treatment. 6.Precise calculation The volume of lesion to be removed is precisely calculated before treatment, and a pre-program is made, which means how much of the nucleus pulposus of the lesion is removed, making the treatment more efficient. These six safety measures are not available in any minimally invasive devices and methods. At present, radiofrequency thermal coagulation target technology is a treatment method with the main purpose of repair, gradually replacing the previous treatment method with the main purpose of speeding up the degeneration of the intervertebral disc.
