Surgical forceps
First Claim
1. A forceps, comprising:
- an end effector assembly, the end effector assembly including;
first and second jaw members disposed in opposed relation relative to one another, at least one of the jaw members moveable with respect to the other from a spaced-apart position to an approximated position for grasping tissue therebetween; and
a knife bar longitudinally translatable with respect to the first and second jaw members between a retracted position, an intermediate position, and an extended position, the knife bar coupled to at least one of the first and second jaw members via a pin-slot engagement such that, upon translation of the knife bar 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 bar from the intermediate position to the extended position, the knife bar is extended to the distal end of the jaw members to cut tissue grasped therebetween.

Abstract
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.

13. A forceps comprising:
-
a handle assembly including a moveable handle moveable between a first position, a second position, and a third position, the handle assembly having a shaft extending distally therefrom; an end effector assembly disposed at a distal end of the shaft, the end effector assembly including; first and second jaw members disposed in opposed relation relative to one another, at least one of the jaw members moveable with respect to the other from a spaced-apart position to an approximated position for grasping tissue therebetween, at least one of the jaw members including a pin extending therethrough; and a knife bar disposed within the shaft and longitudinally translatable with respect to the first and second jaw members between a retracted position, an intermediate position, and an extended position upon movement of the moveable handle between the first position, the second position, and the third position, the knife bar including a slot defined therein that is configured to receive the pin protruding from a proximal flange of the at least one jaw member such that, upon translation of the knife bar 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 bar from the intermediate position to the extended position, the knife bar is extended at least partially between the jaw members to cut tissue grasped therebetween. - View Dependent Claims (14, 15, 16)

17. A forceps, comprising:
-
a handle assembly including a moveable handle moveable between a first position, a second position, and a third position, the handle assembly having a shaft extending distally therefrom; an end effector assembly disposed at a distal end of the shaft, the end effector assembly including; first and second jaw members disposed in opposed relation relative to one another, at least one of the jaw members moveable with respect to the other from a spaced apart position to an approximated position for grasping tissue therebetween, at least one of the jaw members including a proximal flange having a slot defined therethrough that comprises a ramped portion at a distal end thereof and a longitudinal portion at a proximal end thereof; and a knife bar disposed within the shaft and longitudinally translatable with respect to the first and second jaw members between a retracted position, an intermediate position, and an extended position upon movement of the moveable handle between the first position, the second position, and the third position, the knife bar including a pin engaged therein and extending transversely relative thereto that is configured for engagement within the at least one slot such that, upon translation of the knife bar 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 bar from the intermediate position to the extended position, the knife bar is extended at least partially between the jaw members to cut tissue grasped therebetween. - View Dependent Claims (18, 19, 20)
