摘要： A bipolar electrosurgical device is disclosed. The bipolar electrosurgical device includes a handle having a shaft and a distal end. The handle can be coupled to a source of electrical energy and a fluid source. A U-shaped first electrode extends distally in a plane from a pair of openings on the distal end of the shaft. The first electrode is in electrical communication with one of an active pole or a return pole of the source of electrical energy. A longitudinal second electrode extends distally from a middle opening on the distal end of the shaft. The second electrode is coplanar to the first electrode and electrically isolated from the first electrode. The second electrode is in electrical communication with the other of the active pole or the return pole of the source of electrical energy. The second electrode forms a lumen configured to be in fluid communication with the fluid source and a fluid opening for dispersing fluid.

摘要： An electrosurgical device and methods of use thereof. In an embodiment, the device comprises a multipurpose electrosurgical device comprising a handle, a shaft distal to the handle, a first, retractable electrode and a second non-retractable electrode, the electrodes adjacent a distal end of the shaft. The device may be selectively configured for use in a bipolar and a monopolar mode and may provide for selective extension and retraction of the retractable electrode. The retractable electrode may be selectively extended and retracted into a cavity within the shaft. When the retractable electrode is in a retracted position, the device may be configured for use in a monopolar mode. When the retractable electrode is in an extended or fully extended position, the device may be configured for use in a bipolar mode.

摘要： An electrosurgical device having a handpiece including a controller and an electrode assembly extending from the handpiece is disclosed. The electrode assembly includes a monopolar blade and a monopolar electrode. The monopolar blade includes a conductive element partially coated with an insulator and electrically coupled to the controller to selectively deliver a monopolar radiofrequency (RF) cutting signal. The monopolar electrode is spaced apart and electrically isolated from the monopolar blade. The monopolar electrode includes an exposed major conductive surface electrically coupled to the controller to selectively deliver a monopolar RF hemostatic sealing signal with a dispersed fluid.

摘要： An electrosurgical device includes a first shaft defining a proximal end, a distal end, and a lumen therethrough. A fluid delivery tube is disposed within the lumen, the fluid delivery tube defining a proximal end a distal end. An electrically conductive treatment element is in electrical communication with and coupled to the distal end of the first shaft, the electrically conductive treatment element includes a conductive fluid conduit in fluid communication with and affixed within a portion of the fluid delivery tube. A second shaft is in electrical communication with the first shaft, the first shaft being slideably disposed within the second shaft and movable from a first position in which the electrically conductive treatment element is proximate to the distal end of the second shaft to a second position in which the electrically conductive treatment element is advanced a distance away from the distal end of the second shaft.
