The mechanism of plasma ablation coagulation for cervical and lumbar disc herniation: the use of cold ablation cutting technology and thermal coagulation technology to reduce the volume of the nucleus pulposus tissue, reduce the pressure of the intervertebral disc, and release the nerve compression to achieve the purpose of treatment. Specifically: a. Cold ablation technique (40℃) 1mm diameter ablation needle punctures into the center of the nucleus pulposus, firstly, using ablation mode, using 100Hz RF energy to act on the vaporization electrode, surrounding Na+ aggregation (plasma), movement, impact and break the molecular chain of the nucleus pulposus tissue
Then, the tissue will be decomposed into elemental molecules and low molecular gases (O2, H2, CO2), and the nucleus pulposus will be reduced. The ablation needle adopts thermal coagulation mode to act on the nucleus pulposus tissue, which will vaporize, contract and solidify the collagen fibers and reduce the nucleus pulposus.
