Abstract
A forceps includes an end effector assembly having first and second jaw members. Each jaw member includes a proximal flange having an inwardly-facing surface. The proximal flanges are coupled to one another for moving the jaw members relative to one another between a first position and a second position for grasping tissue therebetween. The inwardly-facing surfaces of the proximal flanges are disposed in abutting relation relative to one another. A knife is configured to move along a knife path defined along an outwardly-facing surface of one of the proximal flanges. The knife is movable between a retracted position and an extended position, wherein the knife extends between the jaw members to cut tissue grasped therebetween.
