An endoscope includes a handle, an elongated body extending distally from the handle and defining a longitudinal axis, a light source disposed within the distal portion of the elongated body and configured to illuminate tissue, and a therapeutic unit disposed within the distal portion of the elongated body and configured to treat tissue.

Endoscopes and methods of treatment

A surgical instrument includes first and second shaft members defining proximal and distal end portions and including handles at the proximal end portions thereof. A pivot member couples the distal end portions with a gap defined therebetween proximally of the pivot member. First and second jaw members extend distally from the shaft members, distally of the pivot member. A lockout bar is movable between an unlocked position, withdrawn from the gap, and a locked position, disposed within the gap. The handles are pivotable between spaced-apart and approximated positions to pivot the jaw members between open and closed positions. The handles are yawable between the approximated position and a yawed position to yaw the jaw members between the closed position and a cutting position. The gap provides clearance to permit yawing such that, when the lockout bar is disposed in the locked position, yawing of the handles is inhibited.

Energy-based surgical instrument for grasping, treating, and/or cutting tissue

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.

Energy-based surgical instruments and systems configured to minimize thermal spread

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.

Surgical instruments capable of being selectively disassembled to facilitate replacement of disposable components and/or sterilization of reusable components

A surgical instrument () includes first and second shaft members () defining proximal and distal end portions () and including handles () at the proximal end portions () thereof. A pivot member () couples the distal end portions () with a gap (G) defined therebetween proximally of the pivot member (). First and second jaw members () extend distally from the shaft members (), distally of the pivot member (). A lockout bar () is movable between an unlocked position, withdrawn from the gap (G), and a locked position, disposed within the gap (G). The handles () are pivotable between spaced-apart and approximated positions to pivot the jaw members () between open and closed positions. The handles () are yawable between the approximated position and a yawed position to yaw the jaw members () between the closed position and a cutting position. The gap (G) provides clearance to permit yawing such that, when the lockout bar () is disposed in the locked position, yawing of the handles () is inhibited.
