Temperature monitoring for high frequency welding of soft biological tissues: A prospective study

Determination of Influence Parameters of High Frequency Current on Living Tissues

“…In the study [5], it was shown that when an electric current passes through the tissue between the electrodes, the temperature of the tissue in the center of the welded joint rapidly rises to a temperature 60-70°С coagulation of proteins and denaturation of cells, and then, after turning off the current, the temperature gradually decreases exponentially to the initial values 15-20°С (Fig. 2).…”

“…On the basis of the obtained experimental and clinical data [1][2][3][4][5], the ability of tissue exposed to high-frequency welding to maintain its viability, restore physiological properties and functions through regeneration processes has been demonstrated.…”

“…In particular, it was shown that during high-frequency welding, more labile globular proteins undergo thermal denaturation: an increase in temperature causes a structural transition of the "globulecoil" type, resulting in the formation of glue-like substances. The advantage of the method of high-frequency (HF) welding of living tissues is that it is possible to avoid the presence of foreign material and problems of immune incompatibility [5].…”
