Description
Summary:Electrosurgery (ES) is widely used by surgeons to dissect tissue and control bleeding. Electrosurgical devices achieve these effects through resistive heating of tissue that vaporizes cellular fluid to rupture cells and denatures proteins to produce a hemostatic coagulum. In this paper, the powered electrode of a 13.56 MHz atmospheric pressure plasma jet was employed in contact with tissue samples to vaporize or ablate tissue. In effect, monopolar ES was combined with plasma. We report both significantly higher tissue removal rate and lower electrical current flow through the tissue sample with plasma‐assisted ablation compared to conventional electrosurgical ablation at the same generator output power. magnified image
