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 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.

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 first or second grasping components is movable relative to the other between an open position and a closed position. In the closed position, the first and second tissue-contacting portions cooperate to define a grasping area therebetween. One or both of the first or second 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 therethrough. The first opening is 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.
