A forceps includes an end effector assembly having first and second jaw members disposed in opposed relation relative to one another. One (or both) of the jaw members is moveable with respect to the other from a spaced-apart position to an approximated position for grasping tissue therebetween. A knife is longitudinally translatable with respect to the first and second jaw members between a retracted position, an intermediate position, and an extended position. The knife coupled to one or both of the jaw members via a pin-slot engagement such that, upon translation of the knife from the retracted position to the intermediate position, the first and second jaw members are moved to the approximated position to grasp tissue therebetween and such that, upon translation of the knife from the intermediate position to the extended position, the knife is extended between the jaw members to cut tissue grasped therebetween. |
