Abstract:
1. A surgical instrument, comprising: an end effector assembly having first and second jaw members, at least one of the jaw members movable relative to the other between a spaced-apart position, a first approximated position defining a first gap distance therebetween, and a second approximated position defining a second gap distance therebetween; a knife selectively movable relative to the end effector assembly between a retracted position, a first extended position in which the knife extends between the jaw members a first distance, and a second extended position in which the knife extends between the jaw members a second distance; a trigger selectively actuatable between a un-actuated position, a first actuated position, and a second actuated position for moving the knife between the retracted position, the first extended position, and the second extended position; and at least one control member operably coupled to the trigger, the at least one control member configured to: prevent movement of the trigger from the un-actuated position when the jaw members are disposed in the spaced-apart position, permit movement of the trigger from the un-actuated position to the first actuated position and prevent movement of the trigger beyond the first actuated position when the jaw members are disposed in the first approximated position, and permit movement of the trigger from the un-actuated position to the second actuated position and prevent movement of the trigger beyond the second actuated position when the jaw members are disposed in the second approximated position.
