I. Principle of radiofrequency target point thermal coagulation treatment technology Radiofrequency target point thermal coagulation treatment technology with the help of the electrical stimulation test and impedance test system of the radiofrequency treatment instrument, the video needle is accurately placed to the onset site, through adjusting the size of the radiofrequency output power, setting the treatment temperature and precisely controlling the scope of the damage foci, that is, just using a 0.7mm diameter special puncture needle under the guidance of CT, accurately puncturing to the herniated disc site After confirming the safety, direct video temperature control treatment is performed to promote the molecular movement of the herniated intervertebral disc tissue to generate heat, resulting in the degeneration, coagulation, contraction and volume reduction of the herniated intervertebral disc tissue, thereby 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 disappeared 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, radio frequency targeted thermal coagulation treatment technology features 1, minimally invasive. Puncture treatment does not need to be open, generally hospitalized for 3-7 days, less painful, less complications, not easy to recur, and low cost. 2, high efficiency. Advanced equipment, 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 program. In many minimally invasive treatment of herniated discs today, radiofrequency targeted thermal coagulation is considered to be the safest, most effective, least painful, least complications, 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 treatment technology indications Radiofrequency targeted thermal coagulation treatment technology is mainly applied to disc herniation and posterior spinal nerve pain, but also can be used for the treatment of the following pain 1, neurogenic pain. Trigeminal neuralgia, postherpetic pain, peripheral nerve pain, cancer pain, the corresponding ganglion, nerve plexus and target nerve can be treated by thermal coagulation. 2.Autonomic nerve pain. Abnormal diseases of the autonomic nervous system, hyperhidrosis, myxedema, vaso-occlusive vasculitis. 3.Soft tissue pain. All kinds 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. Several safety measures of radiofrequency targeted thermal coagulation 1. CT guidance, accurate image positioning, to ensure accurate electrode puncture to reach the target site. 2. Real-time monitoring function of impedance, sound synchronization prompt system, can accurately distinguish the specific location where the electrode tip is located, and can distinguish different human tissues such as nucleus pulposus, fibrous ring, calcification point, bone and blood vessel. 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 treatment. 5. Precise calculation of the volume of the treatment range, 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.
