VIRTUAL ELECTRODE FOR HIGH-FREQUENCY FULGURATION AND METHOD FOR MAKING AND USING THEREOF Russian patent published in 2010 - IPC A61B18/14 A61B18/12 A61M1/00 A61M25/00 

FIELD: medicine.

SUBSTANCE: inventions refers to medicine and veterinary science, mainly to surgery, and can be used for fulguration in various organs involved in a pathological process. A virtual electrode for high-frequency fulguration consists of a hollow metal perforated needle surrounded with a layer of biocompatible current-carrying gel. There is a layer of current-carrying low-viscosity liquid between a surface of the needle and gel. A method of high-frequency fulguration with using the electrode includes introduction of the hollow metal perforated needle into a biological tissue, injection of current-carrying gel in the biological tissue followed by high-frequency heating thereof. After current-carrying gel is injected in the biological tissue, current-carrying low-viscosity liquid is infused in the biological tissue in amount 0.5-1.0 of the amount of injected gel, and high-frequency heating of the biological tissue is combined with introduction of current-carrying low-viscosity liquid.

EFFECT: use of the inventions reduces traumatism and labour intensiveness of the fulguration procedure that is ensured by increased coagulation volume per one session.
