Increase of efficiency of electrosurgical tools for welding of live biological tissues

Abstract

Change of shape of electrode cross section can increase efficiency of electrodes of high-frequency electrosurgical tools due to more uniform distribution of current and, thus, reduce local overheating of live biological tissues in their welding. Two-dimensional stationary mathematical model with boundary conditions of the first and second order was developed for creation of new improved tool. It allows analyzing electromagnetic processes in the electrodes of complex cross section shape in a wide frequency band.
