    Abstract: A handle for longitudinal movement of a first tubular member over a second tubular member includes a handle body, a nose cone, a locking mechanism, and a retraction control. The nose cone has a sleeve and an outer wall that define a control channel therebetween. The nose cone is moveable over the handle body between extended and retracted positions. The locking mechanism has locked and unlocked positions for selectively fixing the nose cone in the extended and retracted positions. A finger of the retraction control is positioned within the control channel of the nose cone. The retraction control has first and second positions relative to the nose cone for transitioning the locking mechanism between the locked and unlocked position and for moving the nose cone between the extended and retracted positions.

    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 forceps includes an end effector assembly having first and second jaw members movable relative to one another between a spaced-apart position, a first approximated position, and a second approximated position. One or both of the jaw members including a first stop member coupled thereto and disposed between the jaw members. The first stop member is longitudinally translatable along a surface of the at least one jaw member from a first position, wherein the first stop member inhibits approximation of the jaw members beyond the first approximated position, and a second position, wherein the first stop member inhibits approximation of the jaw members beyond the second approximated position.

    Abstract: An electrosurgical forceps is provided. The electrosurgical forceps includes an end effector including first and second jaw members. One of the first and second jaw members is movable from an open configuration for positioning tissue between the first and second jaw members to a closed configuration for grasping tissue for subsequent electrosurgical treatment thereof. One or more cutting electrodes are positioned on the first and/or second jaw members. The cutting electrode(s) includes one or more piezo-elements that are configured to oscillate at a predetermined frequency when the cutting electrode(s) is energized to sever tissue.

    Abstract: A forceps includes a drive assembly and an end effector assembly having first and second jaw members movable between a spaced-apart position, a first approximated position, and a second approximated position. The drive assembly includes a drive housing and a drive bar. The proximal end of the drive bar is coupled to the drive housing, while the distal end of the drive bar is coupled to at least one of the jaw members. The drive housing and the drive bar are selectively movable in conjunction with one another between a first position and a second position to move the jaw members between the spaced-apart position and the first approximated position. The drive assembly is selectively activatable to move the drive bar independent of the drive housing from the second position to a third position to move the jaw members from the first approximated position to the second approximated position.
