Abstract: A forceps includes a shaft defining first opposed distal recesses, a drive bar slidably disposed within the shaft and defining second opposed distal recesses, and an end effector assembly including first and second jaw members. Each jaw member defines a proximal flange and a distal jaw body. The proximal flanges each define an aperture and a cam slot. A pivot pin extends through the apertures with ends of the pivot pin extending outwardly from the jaw members to be at least partially disposed within the first recesses and fixedly engaged therewith. A drive pin extends through the cam slots with ends of the drive pin extending outwardly from the jaw members to be at least partially disposed within the second recesses and fixedly engaged therewith such that translation of the drive bar relative to the end effector assembly pivots the jaw members between spaced-apart and approximated positions.

Abstract: A surgical instrument includes a housing, a shaft extending therefrom, an end effector assembly supported by the shaft, a movable handle, and a drive assembly. The drive assembly includes a translatable drive member for actuating the end effector assembly, and a torsion spring including first and second legs. The first leg is configured to translate through the housing in response to movement of the movable handle relative to the housing. The second leg is configured to translate through the housing in cooperation with the first leg to move the drive member longitudinally when a force acting on the drive member is less than a threshold force, and to remain in fixed position, thereby tensioning the torsion spring and retaining the drive member in fixed position when the force acting on the drive member is equal to or exceeds the threshold force.

Abstract: A surgical instrument is provided and includes a housing having a shaft. An end effector assembly is operatively connected to a distal end of the shaft and has a pair of first and second jaw members that are movable relative to one another. A drive assembly operably couples to a handle assembly associated with the housing and is configured to impart movement of a respective jaw member when the handle assembly is actuated. A spring component operably associated with each of the jaw members is configured to provide a sealing force at 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. Methods of preparing such forceps for reuse are also provided.

Abstract: A surgical instrument includes a housing, a shaft extending therefrom and supporting an end effector, a knife, and a trigger assembly. The knife is configured to translate between retracted and extended positions. The trigger assembly includes a trigger movable relative to the housing between un-actuated and actuated positions, and a linkage including an apex and first and second bases. The apex is rotatably coupled to the housing about a pivot. The first base is disposed on a first side of the apex and coupled to the trigger. The second base is disposed on a second side of the apex and coupled to the knife. In response to movement of the trigger from the un-actuated to the actuated position, the first base is moved proximally, the apex is rotated about the pivot, and the second base is moved distally to move the knife from the retracted to the extended position.

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 having first and second jaw members. Each jaw member includes a bifurcated proximal flange extending therefrom defining first and second spaced-apart flange components. The first flange components are pivotably engaged to one another via a first engagement portion and the second flange components are pivotably engaged to one another via a second engagement portion. One or both of the jaw members is pivotable relative to the other about the first and second engagement portions between an open position and a closed position for grasping tissue therebetween. A guide member is configured for positioning between the proximal flanges of the jaw members. The guide member includes a tab extending transversely therefrom that is configured to operably engaged one of the first and second engagement portions to retain the jaw members in engagement with one another.
