Abstract: A method for manufacturing an end effector assembly includes providing first and second jaw members moveable relative to one another about a pivot between a first, spaced-apart position and a second, approximated position. One of the first and second jaw members includes a cavity defined therein and the other of the first and second jaw members includes a stop member configured to be inserted into the cavity. A gap-setting gauge is grasped between the first and second jaw members to define a gap-distance between the jaw members equivalent to a thickness of the gap-setting gauge. The first and second jaw members are set such that the jaw members are prevented from approximation beyond the gap-distance.

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.

Abstract: An electrosurgical forceps includes a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly is operably coupled to a distal end of the shaft and includes a pair of first and second jaw members. Each jaw member has a jaw housing and an electrosurgical seal plate. The first jaw member is movable relative to the second jaw member from an open configuration to a clamping configuration. The first jaw member includes an elongated channel defined in its respective jaw housing and extends along a length thereof. A drive assembly operably couples to the first jaw member via a drive rod that is engageable with the elongated channel to move the first jaw member from the open configuration to the clamping configuration and to provide a closure force between the jaw members when the jaw members are in the clamping configuration.

Abstract: A surgical instrument includes a housing that supports an elongated shaft. A selectively movable drive rod extends through the elongated shaft and carries a cam pin in a longitudinal direction. An end effector for surgically treating tissue is supported by the elongated shaft and includes upper and lower jaw members pivotally coupled to one another about a pivot axis. The upper jaw member includes a first pair of laterally spaced flanges, and the lower jaw member includes a second pair of laterally spaced flanges defining a camming slot for engaging the cam pin. The flanges are arranged in an offset configuration where one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.

Abstract: An electrosurgical forceps is provided with a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly includes a pair of first and second jaw members pivotably coupled to one another via a pivot pin. One or both of the first and second jaw members may be movable from an open position for positioning tissue therebetween to a clamping position for grasping tissue. A detent is operably disposed proximal the pivot pin and extends radially outward from a proximal flange of one of the jaw members. The detent is configured to releasably engage a corresponding slot disposed on a proximal flange of the other jaw member. The detent and slot are configured to control a gap distance between the first and second jaw members when the first and second jaw members are in the clamping position.
