1, Overview, the technology belongs to a new technology in the 21st century, different from the traditional methods of surgical resection, drug chemical dissolution and laser vaporization of lumbar disc tissue and other treatment of disc herniation, but the use of conventional minimally invasive spinal surgery techniques that are easy to grasp. It has the advantages of low temperature safety, small trauma without incision, maximum protection of the wall of the annulus fibrosus; small impact on the stability of the spine, low rate of re-protrusion of the intervertebral disc, etc. 2, the development of the technology: “low-temperature plasma ablation” is a medical instrument developed by the United States military science and technology, belongs to the fourth generation of physical therapy technology, in 1999 the United States FDA approval, in clinical treatment began to develop rapidly. 2000 this technology was first applied in the United States in the clinical. The application areas of RF low-temperature plasma ablation include spine surgery, arthroscopic surgery, otolaryngology, plastic surgery, general surgery, and neurosurgery. To date, in the field of spinal surgery and orthopedics, more than 2 million procedures have been performed worldwide. 3.Principle: The principle lies in the use of high-energy plasma field to decompose the tissue molecules, acting on the internal disc, vaporizing and ablating part of the disc nucleus pulposus tissue, and then using precise thermal wrinkling technology to heat up the nucleus pulposus tissue contacted by the blade to about 70 degrees, which reduces the volume of the nucleus pulposus, decompresses the herniated disc, relieves the pressure on the nerve root, and alleviates clinical symptoms. 4, equipment configuration, 5, surgical procedure: the patient takes the patient in the supine position (cervical spine in the supine position, lumbar spine in the prone position), place the metal object, and determine the exact location of the puncture on the x-ray lateral image. Under local anesthesia, the radiofrequency puncture needle is held in the right hand and directly punctured into the intervertebral disc. Withdraw the puncture needle core and insert the special low-temperature plasma radiofrequency ablation wand connected to the bipolar radiofrequency generator. The RF ablation energy level 2 is set, and under the fluoroscopic surveillance of C-arm X-ray machine, 40° to 70 low-temperature RF energy is applied to rotate the ablation and thermal coagulation clockwise in 6 directions at 2, 4, 6, 8, 10 and 12 points of the puncture needle, respectively. Foot ablation key, slowly push the vaporization rod to the end point, and then step on the thermal coagulation key to withdraw the vaporization rod to the starting point to complete a treatment process, the time of ablation and thermal coagulation is 3 minutes each. 6.Postoperative (care, precautions): 3 days after surgery, pay attention to rest in a hard bed, and perform functional exercises for the lumbar back muscles 3 days after surgery. 7, indications: 1, lumbar disc herniation: recurrent lumbar and leg pain, pain is relatively intense, radiating in the direction of sciatic nerve travel, coughing or forceful urination and defecation can make the pain increase, accompanied by numbness, confirmed by CT or MRI corresponding interstitial disc protrusion, and discogenic lower back pain. 2, cervical spondylosis: chronic dizziness and nausea, heavy and painful neck and shoulders with radicular soreness and burning pain in the upper limbs, non-spinal cervical spondylosis patients with MRI confirmed herniated discs in the corresponding interstitial spaces, and cervical discogenic cervical spondylosis. Contraindications: CT or MRI findings showing bony spinal stenosis with bony stenosis or posterior longitudinal ligament as the main compressive factor; huge disc herniation or prolapse; cervical spondylosis of spinal cord type or those with predominantly numbness symptoms only; those with obvious progressive neurological or cauda equina symptoms.
