I. Principle of radio frequency target point thermal coagulation treatment technology Radio frequency target point thermal coagulation treatment technology with the help of radio frequency treatment instrument electrical stimulation test and impedance test system, the video needle accurately placed to the onset of the site, through adjusting the size of radio frequency output power, set the treatment temperature, precise control of the scope of the damage foci, that is, just use a diameter 0, 7mm special puncture needle under the guidance of CT, accurate puncture to the herniated disc site After confirming the safety, the temperature-controlled treatment is directly controlled by video, which will induce molecular movement and frictional heat in the herniated disc tissue, resulting in degeneration, coagulation, contraction and volume reduction of the herniated disc tissue, thus relieving the compression of the nerve. This will release the compression of the nerve without damaging the normal disc tissue and peripheral nerves. After thermal coagulation, the volume of the herniated disc tissue that is compressing the nerve shrinks and is significantly displaced from the nerve root, while the moist heat effect on the injured annulus fibrosus, edematous nerve root, and inflammatory reaction in the spinal canal will have a good therapeutic effect. The entire treatment process is free of obvious discomfort, and the patient’s symptoms are quickly reduced or disappear in only about ten minutes. This treatment does not require surgery, no pain, not easy to recur, is the best method of minimally invasive treatment and precise treatment. Second, radiofrequency targeted thermal coagulation treatment technology features 1, minimally invasive puncture treatment without incision, general hospitalization 3-7 days, less pain, less complications, not easy to recur, low cost. 2, efficient equipment advanced, the machine itself has electrical impedance test function, can identify the nature of the tissue where the needle tip, with electrical stimulation function, can measure the distance between the needle tip and the nerve, to ensure that the nerve is not damaged, the temperature can be controlled treatment range can be controlled to achieve precise treatment. 3, treatment plan In today’s minimally invasive treatment of herniated discs, radiofrequency targeted thermal coagulation is considered to be the safest, most effective, least painful, least complicated, easiest to operate, least expensive, and most widely used new treatment method for cervical and lumbar disc herniation that can treat the herniated area without damaging the nerves and normal disc tissue. Radiofrequency targeted thermal coagulation technology is mainly applied to herniated disc and posterior spinal nerve pain, and can also be used for the treatment of the following pain 1. neurogenic pain trigeminal neuralgia, postherpetic pain, peripheral nerve pain, cancer pain, through thermal coagulation treatment of the corresponding ganglion, nerve plexus and target nerve. 2. Autonomic pain Abnormal diseases of the autonomic nervous system, hyperhidrosis, myalgia, vaso-occlusive vasculitis. 3. Soft tissue pain Various types of soft tissue pain, tennis elbow, Achilles tendon pain, etc. IV. Contraindications to radiofrequency targeted thermal coagulation 1. serious bleeding tendency 2. serious liver and kidney insufficiency 3. disc prolapse or serious central protrusion V. Radiofrequency targeted thermal coagulation treatment? Safety measures 1.CT guidance, accurate image positioning, to ensure accurate electrode puncture to reach the target site. 2. Impedance real-time monitoring function, sound synchronization prompt system, can accurately distinguish the specific location where the electrode tip is located, can distinguish the nucleus pulposus, fiber ring, calcification point, bone and blood vessels and other different human tissues. 3. Precise electrophysiological test function can measure the precise distance between electrode and nerve fiber, which can ensure the safety of thermal coagulation treatment on sensory, motor nerve and spinal cord. 4. Fast and stable controlled temperature rise, humanized design of treatment temperature, strict control of temperature stability during the treatment process. 5. Precise calculation of the treatment range volume, precise control of the volume of thermal coagulation to adapt to the strict requirements of the target treatment. 6. The whole process of treatment only requires puncture of local skin and subcutaneous anesthesia to ensure the sensitivity of deep nerves and avoid puncture injury without the use of analgesics, antibiotics and hormones. 7. After radiofrequency treatment, the lumbar intervertebral disc and nearby anatomical structures will not be damaged and will not affect the open surgery when necessary. 8. There are no important large blood vessels on the puncture path, and bleeding can be avoided.
