Development of Radio-Frequency Electrosurgical Unit EHVCh-1.76

This article describes the main stages and principles of the development of the EHVCH-1.76 electrosurgical unit, examines the mechanisms of the high-frequency current on the tissue. The article presents the main load characteristics of the device and methods for their correction for better optimization of modes when working with specific types of biotissues and better and faster performance of tasks assigned to the medical staff. As the results of the work is presented a working model of the device with the expanded functional, incl. a touch panel designed to improve the convenience of setting the device, argon-plasma coagulation, used for coagulation of large surfaces without carbonization of tissues, auto-shutdown functions in time and the degree of coagulation of biological tissue in bipolar coagulation, and many others.
