The topicality of temperature monitoring for tissues in the electrosurgical treatment of uterine myoma has been substantiated. A method for estimating the heating temperature of biological tissue based on measuring the relaxation frequency of the processed biological tissues is proposed. Geometrical and mathematical models were developed for calculating the thermoelectric characteristics of biological tissues when exposed to high-frequency electric current. A computational experiment was carried out to study the effect of the heating temperature of biological tissue in the resection area on its relaxation frequency. As a result of the study conducted, a linear dependence was established between the heating temperature of biological tissues and its relaxation frequency for a given needle electrode geometry.
