[The technology of high-frequency cold-hot plasma ablation for small invasive electrosurgery].
The mechanism of high-frequency cold-plasma ablation is radically different from thermal impact by high-frequency current in traditional high-frequency surgery. As for the former, the effect is insured due to a local low-temperature molecular disintegration of tissue with the tissue being simultaneously removed from the surgery zone. The technology is based on induction of a stable plasma stratum in the plasma-forming medium by using a high-frequency generator. Kinetic processes occurring in a stationary strongly ionized plasma are under discussion in the paper. The function of the distribution of carriers of the ion containing (Na+, Cl-, K+, Cl-) plasma charge is shown to be close to Maxwellian distribution. The described evaluations of parameters are fundamental criteria for designing a unit that ensures the process of high-frequency cold-plasma ablation. Finally, the stability criteria were analyzed for the low-temperature plasma field.
