Radiofrequency (radiofrequencyRF) treatment technology is a technique to treat diseases by precisely outputting ultra-high frequency radio waves through specific puncture needles to produce local high temperature in local tissues and play the role of thermal coagulation or cutting, so it is called “radiofrequency thermal coagulation” or “radiofrequency ablation”. The radiofrequency instrument used for pain treatment is specially equipped with nerve stimulation function, which can find and accurately locate the sensory and motor nerves, and block or change the nerve conduction with radiofrequency current, which can achieve the purpose of relieving pain. This physical neurothermal coagulation technique provides excellent control of the temperature and range of the thermal coagulation foci, and can reduce or eliminate pain while maintaining proprioceptive, tactile and motor functions after treatment. The main advantage of radiofrequency technology over other existing nerve destruction techniques is the availability of quantitative and predictable neurothermal coagulation foci. Radiofrequency ablation of the intervertebral disc, also known as minimally invasive disc radiofrequency ablation (PIRFT) and disc radiofrequency targeted thermocoagulation, involves the penetration of a radiofrequency needle into the herniated disc of the herniated disc and heating it so that protein coagulation of the herniated disc occurs, the internal pressure of the herniated disc decreases and retracts, while repairing the annulus fibrosus and relieving the compression and irritation of the nerve, to the effect of not affecting the nucleus pulposus within the disc. At the same time, ozone injection treatment can be performed through radiofrequency needles. Minimally invasive intervertebral disc radiofrequency ablation has four major advantages: precise positioning and high safety The treatment process is precisely positioned under C-arm guidance, monitored at the time under digital subtraction, acting directly on the diseased protrusions, the whole operation is visualized and does not injure the surrounding normal tissues and organs, and the radiofrequency temperature is controlled to ensure safety before and after treatment, no infection and no thermal injury. Small invasion and no pain The puncture needle is only 0.7 mm, no incision, no bleeding, and the whole procedure takes about 30 minutes, which will not cause any loss of spinal stability after the operation, with little danger and quick recovery. The effect is rapid and precise. RF has a unique impedance display function, which can distinguish the nucleus pulposus fiber ring, calcification points, bone and blood vessels. It can accurately calculate the volume to be removed, target directly locate the herniated area, precisely ablate the herniated material, release the nerve root compression or irritation, quickly relieve pain symptoms, reshape the fibrous ring, and treat cervical and lumbar disc herniation in one step. Wide range of age adaptation The whole treatment only uses local anesthetic and no analgesic, which is less disturbing to human physiology and has no side effects, making the treatment greener and more humane, and safer for senior patients. The four main effects of minimally invasive disc radiofrequency ablation bring the safety and efficacy issues that doctors and patients are most concerned about to the forefront, making it easier and more comfortable for doctors to perform spinal surgery to cure herniated discs, and changing the previous treatment method of accelerating degeneration to a treatment method that focuses on repair. At the same time, the treatment of intervertebral discs is gradually being led from surgery to minimally invasive.
