MULTIPURPOSE ELECTROSURGICAL DEVICE

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.

主权项

1. A multipurpose electrosurgical device comprising:
a handle; a shaft distal to the handle; a first electrode and a second electrode adjacent a distal end of the shaft; wherein the first electrode and second electrodes are laterally and spatially separated, comprise one of a same size and a same shape and each have a blunt, rounded distal end; wherein the first electrode is an upper, retractable electrode that is movable relative to the shaft and is configured to retract into a cavity of a sleeve adjacent the distal end of the shaft; and wherein the first electrode is coupled to a first fluid delivery shaft having a first fluid delivery lumen and a first fluid outlet and the second electrode is coupled to a second fluid delivery shaft having a second fluid delivery lumen and a second fluid outlet.
