Heterogeneous Recombination in Steam Plasma as a Mechanism of Affecting Biological Tissues

摘要

High-frequency electrosurgery is a well-known and widely used method of cutting and coagulating bio_logical tissues in various areas of surgery [1]. At the same time, the investigations carried out in the last years in the field of interaction between the low-tem_perature plasma of the high-frequency glow discharge and biological tissues have made it possible to develop substantially new electrosurgical technologies. In the majority of electrosurgical devices, the cutting effect is usually achieved due to heat released in a biological tissue when a high-frequency current flows through it [2, 3]. The heat release in this case is associated with conduction currents or dielectric losses when using high frequencies (tens of MHz and higher).
