摘要：
An end effector assembly for a surgical instrument includes a pair of jaw members each including one or more tissue-contacting plates. One or both jaw members is movable relative to the other between spaced-apart and approximated positions for grasping tissue between the tissue-contacting plates. The tissue-contacting plates are adapted to connect to a source of energy for conducting energy through tissue grasped between. One of the jaw members includes an insulative member extending towards the other member. The insulative member includes a plurality of crests each defining a blunt apex and a proximally-facing sharpened edge. The blunt apexes contact tissue upon approximation of the first and second jaw members to grasp tissue, while the proximally-facing sharpened edges facilitate tissue cutting in a ripping fashion upon proximal translation of the end effector assembly relative to tissue.
