摘要：
An electrosurgical device comprises an elongated shaft having an axis with an interior channel extending along the axis to an opening in a distal end of the shaft. The channel is configured to be coupled to a negative pressure source, and an electrode with a conductive, usually hook-shaped, distal portion is coupled to the shaft and moveable between a first position in which a distal tip of the electrode is disposed proximate to a periphery of the opening of and a second position in which the distal electrode tip is exposed and spaced apart from the opening.
