Abstract: A surgical instrument includes a housing, a shaft coupled to and extending distally from the housing, an end effector assembly disposed at a distal end of the shaft, a movable handle coupled to the housing, a drive assembly coupled to the end effector assembly, and an extension mechanism disposed within the housing. The extension mechanism is configured to couple to the shaft and between the movable handle and the drive assembly for moving the shaft and drive assembly between a retracted position and an extended position relative to the housing. The extension mechanism is coupled between the movable handle and the drive assembly in each of the retracted and extended positions such that the movable handle is operable to effect manipulation of the end effector assembly in each of the retracted and extended positions.

Abstract: An electrosurgical forceps includes a first elongated shaft member including a first handle member and a first jaw member having a first tissue contacting surface, and a second elongated shaft member including a second handle member and a second jaw member having a second tissue contacting surface. At least one of the first and second handle members is movable relative to the other between an open position, a first approximated position where the first and second tissue contacting surfaces are diametrically opposed to one another, and a second approximated position where the first and second tissue contacting surfaces are laterally offset from one another. A handle connector assembly is selectively engageable with the second handle member and is configured to selectively communicate electrosurgical energy between the first and second tissue contacting surfaces when the first and second handle members are disposed in the first approximated position.
