1.Working principle Specific 100KHz ultra-low frequency electrical energy excitation medium (Nacl) to generate plasma, in the temperature range of 40-70 ℃ protein reversible denaturation, relying on the “plasma” generated by the sound waves to break the molecular bonds, the protein and other biological macromolecules directly cleaved into O2, CO2, N2 and other gases, thus At the cost of “minimally invasive” to complete the ablation of intervertebral disc tissue, cutting, perforation, crumpling and hemostasis and other functions. 2.Operating method Radiofrequency ablation adopts local anesthesia, and under the surveillance of C-arm X-ray machine, a puncture needle is inserted into the intervertebral disc percutaneously, and then a low-temperature plasma tip is introduced into the intervertebral disc through the core of the needle to make part of the protruding disc tissue vaporize and disappear through low-temperature plasma radiofrequency ablation, and produce heat therapy and contraction to the surrounding disc tissue, so as to reduce the pressure in the disc and relieve the patient’s symptoms. . The whole treatment process takes about 30 minutes. 3, indications (1) lumbar disc herniation: recurrent lumbar and leg pain, pain is more intense, radiating in the direction of the sciatic nerve, coughing or forceful urination and defecation can make the pain increase, accompanied by numbness, confirmed by CT or MRI corresponding interstitial disc herniation, and discogenic lower back pain. (2) Neurogenic cervical spondylosis: patients with chronic dizziness and nausea, heavy and painful neck and shoulder with radicular soreness and burning pain in the upper limbs, non-spinal cervical spondylosis in which the corresponding interstitial disc is confirmed to be herniated by MRI, and cervical discogenic cervical spondylosis. 4. Contraindications CT or MRI examination results show bony spinal stenosis, with bone redundancy or posterior longitudinal ligament as the main pressure-causing factor; huge disc herniation or prolapse; cervical spondylosis of spinal cord type or those with only numbness as the main symptom; those with obvious progressive neurological symptoms or cauda equina symptoms. If the minimally invasive treatment effect is not satisfactory, the patient is still suitable for the implementation of other surgical treatments to facilitate the final improvement of the disease outcome. The technique is simple, safe and minimally invasive, with significant efficacy, fast recovery and no incision, and hospitalization takes only 3 days.
