ELECTROSURGICAL INSTRUMENT FOR DELIVERING RADIO FREQUENCY (RF) AND/OR MICROWAVE ENERGY TO BIOLOGICAL TISSUE Russian patent published in 2022 - IPC A61B18/18 A61B18/14 A61B1/05 A61B1/07 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to medical equipment, namely, to an electrosurgical instrument, an electrosurgical apparatus, and an electrosurgical system for delivering radio frequency and/or microwave energy to biological tissue. Electrosurgical instrument comprises a coaxial cable, an emitting tip, an image sensor, and an attachment. The coaxial cable is intended for transmitting radio frequency and/or microwave energy. The cable has an internal conductor, an external conductor, and a first dielectric material. The external conductor is formed coaxially with the internal conductor. The dielectric material separates the internal conductor and the external conductor. The emitting tip is located at the distal end of the coaxial cable for receiving radio frequency and/or microwave energy from the coaxial cable. The image sensor is located at the distal end of the coaxial cable for creating digital images of the processed area. The image sensor is installed at the distal end of the cable for transmitting images. The coaxial cable and the image-transmitting cable are connected with the attachment and extend therefrom. The attachment comprises a communication module for transmitting information related to the digital images to a remote apparatus. The communication module comprises a transceiver connected to a wireless network for exchanging data. The electrosurgical apparatus comprises the electrosurgical instrument and a display apparatus for receiving and displaying information related to the digital images. The electrosurgical system comprises an electrosurgical generator and an electrosurgical instrument. The electrosurgical instrument is therein connected to the electrosurgical generator for receiving radio frequency and/or microwave electromagnetic energy and transmitting said energy to the coaxial cable.

EFFECT: structural features of the attachment and the image sensor integrated into the electrosurgical instrument provide a compact positioning of the systems wherein electrosurgical processing is visualised, simultaneously with transmission of clear images allowing the physician to better identify tissue areas in need of processing, as well as allowing the physician to perform more accurate processing.
