Abstract
An electrosurgical instrument includes at least one shaft member, an end effector assembly extending distally from the at least one shaft member, and a heat pipe. The end effector assembly includes first and second jaw members, each including an electrically-conductive tissue-contacting surface. At least one of the first or second jaw members is movable relative to the other about a pivot between a spaced-apart position and an approximated position for grasping tissue between the electrically-conductive tissue-contacting surfaces. The heat pipe includes a proximal body portion and a flattened distal portion. The proximal body portion extends through at least a portion of the at least one shaft member, and the flattened distal portion extends through at least a portion of the first jaw member. The heat pipe is configured to facilitate drawing heat proximally from the end effector assembly.
