摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A forceps includes an end effector assembly having first and second jaw members moveable with respect to one another between an open position and a closed position. A knife channel having a body and a base is defined within each jaw member. A knife assembly includes a knife having a bifurcated distal end. The bifurcated end includes first and second cutting members each defining an opposed cutting surface and having a tab at a free end thereof for translation through the base of a knife channel. The knife is translatable into the channels when the jaw members are in the closed position such that the cutting members are approximated when translated through the channels. The knife is also translatable into the channels when the jaw members are in the open position such that the cutting members are flexed apart when translated through the jaw members.
