at least one shaft having a proximal end and a distal end; an end effector assembly coupled to the distal end of the at least one shaft, the end effector assembly including:
first and second jaw members, each jaw member defining an opposed surface, at least one of the first and second jaw members movable relative to the other between a spaced-apart position and an approximated position for grasping tissue within a grasping area defined between the opposed surfaces; anda first tissue-treating plate disposed on the first jaw member or the second jaw member and adapted to connect to a source of energy, a second tissue-treating plate disposed on the first jaw member or the second jaw member and adapted to connect to a source of energy, the first and second tissue-treating plates configured to conduct energy therebetween for treating tissue disposed within a tissue-treating area defined between the first and second tissue-treating plates, each of the first and second jaw members defining a knife channel positioned within the grasping area and outside of the tissue-treating area; and a knife assembly including a knife slidably disposed in one of the at least one shafts, the knife selectively movable relative to the end effector assembly between a retracted position, wherein the knife is positioned proximally of the first and second jaw members, and an extended position, wherein the knife extends at least partially through the knife channels of the first and second jaw members to cut tissue positioned adjacent the tissue-treating area. |
