Lumbar current catheter ablation is a minimally invasive procedure performed in the CT room. From the accurate positioning of the puncture point, the position of the current catheter is repeatedly adjusted under CT until it is satisfactory, and before radiofrequency ablation, diluted photographic agent is injected from the catheter around the nerve root to view the integrity of the dural sac, then lidocaine, Depo-Provera, saline and other drugs are injected from the current catheter, and finally radiofrequency ablation is performed. The procedure takes about 1 hour, is quick, minimally invasive, reliable, and worthy of clinical promotion. Features and advantages of lumbar spine radiofrequency current catheter ablation: 1. Accurate positioning and safety: lumbar spine radiofrequency current catheter ablation treatment is accurately positioned under CT, the precise guidance of CT acts directly on the lesioned nerve root, the data is accurate to less than 1mm, the angular error is less than 1 degree, which improves the accuracy of treatment and almost does not hurt any normal tissue. The precise identification and stimulation function of the nervous system, which is unique to RF for the nervous system, can measure the nerve within 1mm of the treatment range and distinguish the motor nerve or sensory nerve precisely, the accuracy of which can be imagined. 2.Unique nerve root imaging function: after accurate positioning, nerve root imaging is performed, which can distinguish the location of nerve roots and dura mater, ensuring the accuracy and safety of treatment. 3.Controllable temperature: RF instrument can adjust the temperature arbitrarily, the highest temperature is below 42 degrees Celsius, which ensures the safety before and after the treatment, no infection and no heat damage. 4.No damage to normal tissues: the precise calculation function of RF for neurological system can accurately calculate the temperature and frequency of RF before treatment, without hurting any normal tissues, making the treatment more humane and effective. Whether it is laser, spinal canaloscopy, fiber ring repair, ozone or collagenase injection, percutaneous excision and suction, the good nucleus pulposus is removed and the diseased part is allowed to retract. 5, humanized treatment: the entire treatment process of the neurological special RF instrument uses local anesthetics, does not use analgesics, antibiotics, no side effects on the human body, making the treatment greener and more humanized. At the same time, it has changed the history of intervertebral disc treatment, changing the treatment method with the main purpose of accelerating degeneration to the treatment method with the main purpose of repair. The safety, minimally invasive and rapid onset of effect of lumbar radiofrequency current catheter ablation is unmatched by other methods. This treatment is epoch-making in the history of minimally invasive spine treatment and has been well received by patients with lumbar and leg pain.
