ISOLATING DEVICE FOR ELECTROSURGICAL DEVICE Russian patent published in 2022 - IPC H01P1/207 H01P1/36 A61B18/18 

FIELD: medical equipment; electrosurgery.

SUBSTANCE: invention relates to the field of electrosurgery by radiation. The group of inventions contains a combined insulator-diplexer device for transmitting radio frequency (hereinafter – RF) energy and microwave energy obtained from separate sources to a probe through a common signal path. The invention combines in one unit all necessary components to isolate a microwave channel from a RF channel, while simultaneously providing high withstand voltage (for example, more than 10 kV), contains a waveguide insulator for insulating the microwave channel, in which a pair of DC insulating barriers is located, to provide a pair of series-connected capacitive structures between a grounding conductor at the output of a signal addition circuit and a conductive input section of the waveguide insulator, as well as an electrosurgical device containing it.

EFFECT: improvement of insulation properties.
