Abstract: A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable is housing is configured to be releasably coupled to at least one of the shafts and an electrode assembly is configured to be releasably coupled to the disposable housing. The electrode assembly includes electrodes releasably coupled to the jaw members. At least one of the electrodes includes a knife channel configured to receive a knife blade therethrough to cut tissue grasped between the jaw members. A tissue stop has a knife slot that aligns with the knife channel to receive the knife blade. An actuation mechanism advances the knife blade through the knife channel to cut tissue.

Abstract: A surgical instrument includes an end effector assembly including first and second grasping components each defining a tissue-contacting portion. One or both of the grasping components is movable relative to the other to a closed position wherein the tissue-contacting portions cooperate to define a grasping area therebetween. One or both of the grasping components is configured to apply energy from the tissue-contacting portion thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion of the first grasping component defines a first opening disposed within the grasping area and in communication with a first lumen defined at least partially through the first grasping component. The first lumen is adapted to connect to a source of vacuum to enable aspiration through the first opening.

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 end effector assembly for a forceps includes first and second jaw members each having an opposed electrically-conductive tissue-contacting surface. The first jaw member is pivotable relative to the second jaw member between a spaced-apart position and an approximated position for grasping tissue between the opposed electrically-conductive tissue-contacting surfaces. The second jaw member includes an electrical cutting element and is translatable relative to the first jaw member between a first position, wherein the opposed electrically-conductive tissue-contacting surfaces are aligned with one another, and a second position, wherein the opposed electrically-conductive tissue-contacting surfaces are longitudinally offset relative to one another. Upon translation of the second jaw member between the first and second positions, the electrical cutting element is translated at least partially along the opposed electrically-conductive tissue-contacting surface of the first jaw member.

Abstract: A forceps includes a first portion and a second portion. The first portion includes a shaft, an end effector assembly disposed at a distal end of the shaft, and a drive assembly including a drive bar. The end effector assembly includes jaw members movable between spaced-apart and approximated positions. The drive bar is slidably disposed within the shaft and coupled to the end effector assembly such that translation of the drive bar relative to the shaft moves the jaw members between the spaced-apart and approximated positions. The second portion includes a housing (or portion thereof) and a handle assembly including a movable handle that is coupled to the housing and movable relative thereto between first and second positions. The first and second portions are releasably couplable with one another to operably couple the movable handle with the drive bar such that moving the movable handle actuates the jaw members.
