ENDOSCOPIC ELECTRODE FOR TREATING BIOLOGICAL TISSUES WITH NONEQUILIBRIUM COLD PLASMA Russian patent published in 2022 - IPC A61B18/00 A61B18/06 

FIELD: medical equipment.

SUBSTANCE: endoscopic electrode for treating hollow tubular organs with nonequilibrium cold plasma constitutes a bipolar coaxial electrode containing, on the inside, a high-frequency electrode made in the form of a rounded conductive rod, coated with a layer of a dielectric at the distal end, and provided with a plug at the distal end, rigidly fixed by means of a cuff with at least one gas supply hole, surrounded by a grounded electrode in the form of a right hollow cylinder with a plug in the distal area, and with the presence of at least one outlet along the side wall of the grounded electrode providing the discharge of the active products of plasma chemical reaction.

EFFECT: application of the invention allows for the correction of pathological changes on the side of mucosae of internal tubular organs, excluding direct plasma contact with the organ that may cause the passage of current through the tissues.
