Abstract
An endoscopic implement including two electrodes connected to the terminals of a high frequency generator and mounted to a distal end of an elongated insertion element. An insulator is disposed between and secured to the two electrodes. One of the electrodes is mounted to a lateral surface of the insulator at a location that is laterally spaced from an axis of the insertion element. The other electrode is mounted at a distal end of the insulator.
Claims4
An endoscopic implement comprising an elongated insertion element defining an axis and having a first electrode and a second electrode, each of said electrodes adapted to be connected to a terminal of a high frequency generator and being mounted at a distal end zone of the elongated insertion element with an insulator being disposed between said electrodes, wherein each of said first and second electrodes has a flat, planar face, and wherein said first electrode defines a first plane that is oriented generally perpendicular to said insertion element axis while said second electrode defines a second plane that is oriented generally parallel to said insertion element axis such that when one of said first and second electrodes is in engagement with tissue the other of said first and second electrodes is configured to be spaced from the tissue so as to be freely disposed in liquid adjacent the tissue.
