Dual-channel injection bipolar high frequency electrosurgical knife
The granted patent US12035960B2 describes a dual-channel injection bipolar high-frequency electrosurgical knife designed for precise tissue cutting and liquid injection. The device comprises three main components: an electrode part, a main part, and an operation part. The electrode part features an active electrode that can extend or retract, equipped with a hollow tubular portion and a protrusion at its distal end. This active electrode is insulated from an inert electrode by a hollow tube and a protruding structure, allowing liquid to flow between them. The main part includes an insulation sheath with two channels: one for the active electrode and another for a wire connected to the inert electrode. The operation part connects to the active and inert electrodes and includes liquid inlets for separate liquid flow.
Additional features of the electrosurgical knife include a barb structure on the inert electrode for engagement with the insulating part, and a seal that forms a second liquid passageway. The design incorporates anti-blocking coatings on the surfaces of the electrodes and utilizes a conductive screw with an insulating coating for enhanced functionality. The active electrode's protrusion is designed to prevent over-extension or retraction, ensuring operational safety. The patent outlines various configurations for the liquid passageways and the materials used, such as metal oxide for insulation, specifically zirconia. Overall, this innovative electrosurgical knife aims to improve surgical precision and efficiency through its dual-channel liquid delivery system and advanced electrode design.
