Abstract
Development of effective new models of high-frequency electrosurgical instruments is an important problem, although each individual project requires special technological and economic substantiation and marketing prognosis. For example, development of a high-frequency argon jet coagulator was canceled in the Laboratory of Electrosurgical Instruments, All-Russian Scientific-Research Institute for Medical Instrument Engineering (VNIIMP-VITA Joint-Stock Company) at the prototype stage for economic reasons. Indeed, the cost of the newly developed instrument is about 4–5 higher that the cost of the Politom-2, while the efficiency of the argon jet electrode is only 15–20% as higher. Besides, lack of centralized supply of medical institutions with argon significantly reduces the efficiency of the argon jet coagulator.
