Аннотация

The results of the analysis of the physical basis and clinical application of high frequency monopolar and bipolar electronic devices in surgery are presented in the paper. The efficiency of high-frequency radio-wave method in the treatment of benign skin tumors was evaluated. The radio-wave method includes a set of effects on the biological tissue to dissect them (electrotomy), purposeful destruction, stop bleeding and mechanical fixation (coagulation), and local removal of biotissues (ablation). The device operates in the frequency range 1.76-3.50 MHz and provides: discrete output power control in all operating modes; light indication of supply voltage of the power supply network and output power level; sound frequency-tone alarms. It is shown that most of the high-frequency energy in monopolar systems is concentrated and converted to heat near the active electrode. The advantages of the method of high-frequency radio-wave surgery for the treatment of neoplasms of the skin are proved: the operation is performed practically bloodless, there is no risk of atrophic and hypertrophic scarring, the risk of infection of the patient is reduced, the improvement of reparative processes due to the temperature effect and reliability, and reduced postoperative period. It indicates 89 % efficiency of the radio wave methods used for the cutaneous neoplasms removal.
