Abstract: 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.

Abstract: A forceps includes an end effector assembly having first and second jaw members movable between a spaced-apart position and an approximated position for grasping tissue therebetween. A knife assembly having a cutting blade disposed at a distal end thereof is also provided. The knife assembly is translatable relative to the end effector assembly between a retracted position and an extended position, wherein the cutting blade extends between the jaw members to cut tissue grasped therebetween. The knife assembly includes a proximal component and a first distal component that includes the cutting blade. The proximal and first distal components are removably coupled to one another to facilitate replacement of the first distal component while the end effector assembly remains in a substantially assembled condition, i.e., without requiring substantial disassembly of the end effector assembly.

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 forceps includes an end effector assembly including a pair of jaw members disposed in opposing relation relative to one another. At least one jaw member is moveable relative to the other between a spaced apart position, a first approximated position, and a second approximated position. The jaw members are configured to apply a pre-determined pressure to tissue disposed therebetween in each of the first and second approximated positions. A sealing pressure is applied to tissue disposed between the jaw members when the jaw members are in the first approximated position. A cutting pressure is applied to tissue disposed between the jaw members when the jaw members are in the second approximated position.

Abstract: A jaw member for use with an electrosurgical forceps includes a support member having a first surface and a pair of depending sides which extend therefrom forming a generally U-shaped configuration. The free end of the sides each including a flange which extends outwardly therefrom which is designed to attach to an electrically conductive plate such that the plate bridge the two flanges to enclose the U-shaped support member to form a box-like skeleton having a cavity defined therein. An insulative material is disposed within the cavity and an insulative cover is disposed about a periphery of the box-like support skeleton to insulate surrounding tissue during activation of the conductive plate.

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.
