Plasma disc nucleus pulposus ablation is a safe, minimally invasive treatment for cervical and lumbar disc herniation. This minimally invasive technique is used to treat symptoms related to nerve irritation caused by increased intradiscal pressure. It is a method of controlled nucleoplasty and disc decompression through plasma cryo-precision ablation and thermal wrinkling techniques. The principle is that plasma ablation technology combines thermal coagulation and ablation to remove part of the nucleus pulposus, using low-temperature plasma ablation technology to vaporize part of the nucleus pulposus in real time to achieve the purpose of reducing the volume of the nucleus pulposus; and then using precise thermal wrinkling technology to heat up the nucleus pulposus tissue contacted by the blade to about 70°C to reduce the total volume of the nucleus pulposus and reduce the pressure in the disc to achieve decompression. treatment purpose. Cryo-plasma ablation is a revolutionary minimally invasive surgical technique that does not rely on thermal energy. It generates low-temperature plasma in front of the cutter head and uses the kinetic energy of the ions moving at high speed in the plasma to break the molecular bonds of the target tissue, working at a temperature of 40-70°C. Therefore, not only is the surgical precision extremely high, but the depth of thermal damage is far less than that of traditional electrosurgical devices and laser devices. Due to the patented bipolar structure of the cutter head, the electric field does not enter the patient’s body and the vaporization of the tissue is precisely controlled within the extremely thin plasma layer at the front of the cutter head, and the cutting accuracy of the plasma knife can reach the order of microns. Through plasma ablation technology, radiofrequency energy is applied to a conductive medium to form a highly convergent low-temperature plasma layer around the electrode with excitation energy. The plasma thin layer consists of highly ionized particles that have sufficient kinetic energy to break the peptide bonds of large molecules in the tissue, causing them to break down into low molecular weight molecules and low molecular weight inert gases, the latter of which can be expelled from the body through the puncture channels. Our clinical practice in the pain department of Nanjing Gulou Hospital has also found that if controlled at the right time the plasma tip can also carry out the diseased nucleus pulposus tissue that breaks the peptide bonds, resulting in the magic of removing the nucleus pulposus with a straight needle and achieving less trauma and better results. Plasma ablation only generates a temperature of 53°C, and the temperature 1mm away from the surface of the needle tip is less than 43°C. Under proper operation, there is no thermal damage to other surrounding tissues. This is where it is superior to laser and superior to RF. Plasma surgery has a real-time ablation function, and intraoperative decompression is evident, and patients often feel relief on the affected limb before they even get off the table. The plasma tip also allows precise temperature control at 60-70°C, which causes the collagen molecule spiral structure to crumple, thus achieving a shaping effect. Indications for the application of low-temperature plasma electric knife: 1, cervical spondylosis shoulder and neck pain, heavy with obvious upper limb radicular soreness, burning pain, numbness and other symptoms and confirmed by MRI corresponding gap disc herniation patients; 2, lumbar intervertebral disc herniation and patients with lumbar spinal stenosis caused by yellow ligament hyperplasia or extensive disc bulge.
