Low-temperature plasma vaporization and melting cutting technology: a thin layer of plasma is formed at a lower temperature (40-70℃), a large amount of Na+ is absorbed around the vaporization rod, these plasma particles move under the action of the energy provided by the head of the vaporization rod, and when it gets enough energy the molecular chains between the tissue cells are impacted and broken to form elemental molecules and low molecular gases (O2, CO2, H2, etc.), using plasma The low-temperature vaporization technology of cold fusion cutting removes part of the nucleus pulposus tissue, completes the remodeling of the nucleus pulposus tissue in the intervertebral disc, and uses the heating technology to vaporize, contract and solidify the collagen fibers in the nucleus pulposus to reduce the total volume of the intervertebral disc, thus reducing the pressure in the disc and alleviating the stimulation of the nerve roots by the intervertebral disc tissue for the purpose of reducing back and leg pain. It directly relieves the pressure and stimulation on the spinal cord and nerve roots, causing the symptoms and signs to rapidly reduce or disappear; at the same time, the remodeling of the nucleus pulposus is completed before the rupture of the annulus fibrosus. Thus, the continued rupture of the fibrous ring and the function of the herniated nucleus pulposus are prevented. In addition to reducing the pressure within the disc, plasma radiofrequency ablation has the potential to reduce the inflammatory response within the degenerated disc. Indications for low-temperature plasma treatment of cervical spondylosis include: 1, clinical manifestations of neck and shoulder pain, radicular pain and/ or scattered sympathetic symptoms, seriously affecting daily life, various conservative treatments for 2-3 months are ineffective; 2, MRI shows inclusive cervical disc herniation rather than disc prolapse, neck and shoulder pain and upper extremity pain are severe, the implementation of open surgery indications and procedures are controversial; 3, preoperative via selective small joint block If the cause of pain is determined to be disc but not small joint. The following conditions are not suitable for this technique: 1.Disc height <50% of normal disc height; 2.Severe disc degeneration; 3.Moderate to severe spinal stenosis; 4.Spinal fracture, infection, tumor. Plasma radiofrequency ablation has the following features compared with other cervical disc herniation treatment: 1, can remove part of the nucleus pulposus without causing irreversible damage to the surrounding normal tissues (bleeding, necrosis, etc.), does not affect the stability of the spine; 2, good safety, because the patient remains awake during surgery, can reflect the discomfort of surgical treatment in a timely manner, so that the operator can adjust the position of the plasma tip and energy size in a timely manner; 3, easy to grasp the operation, short surgery time; 4, small puncture needle hole (about 1.5mm), no blood leakage through the puncture channel, minor injury; 5, less pain, short hospitalization time, early activity; 6, surgery is not effective, does not affect further open surgery or other minimally invasive treatment.
