Abstract
A surgical instrument for electrosurgery having a first forceps arm, a first forceps jaw of the first forceps arm, a first conductor tip of the first forceps arm, a second forceps arm disposed opposite the first forceps arm, a second forceps jaw of the second forceps arm, the second forceps jaw disposed opposite the first forceps jaw, a second conductor tip of the second forceps arm, and the second conductor tip disposed opposite the first conductor tip. The first forceps arm and the second forceps arm are configured to transfer thermal energy away from the first conductor tip and second conductor tip at a rate sufficient to maintain the thermal energy of the first conductor tip and second conductor tip below a designated thermal threshold.
