Abstract
In the paper a method of temperature monitoring for high frequency welding of soft tissues is presented. The method enables to investigate the distribution of temperature fields in biological tissues. This allows to assess the influence of the skin effect on current passage in a process of electrosurgical interventions.The present paper describes an investigation of distribution of temperature fields in biological tissues affected by electrosurgery upon use of an infrared thermograph. In the experiment, the dynamics of temperature distribution in the tissue was registered upon using thermal imaging cameras FLIR i7. Ablation of the tissues by HF current was performed with ЕКВЗ-300 unit (E.O. Paton Electric Welding Institute). Most important result of application of the method of temperature monitoring is an establishment of the moment for removal of the electrodes that ensures an avoidance of carbonization of the cardiac tissues during their ablation
