Abstract: A forceps includes a pair of shaft members, a pair of jaw members each including a distal body and a proximal flange, and a pair of electrode plates. The proximal flanges are engaged with the respective shaft members and pivotably coupled to each other such that pivoting the shaft members pivots the distal jaw bodies. The electrode plates each includes a tissue-contacting portion disposed on the distal body of the respective jaw member and a proximal extension portion extending at least partially through the proximal flange of the respective jaw member. The tissue-contacting portion and proximal extension portion of the first electrode plate are disposed in perpendicular planes relative to each other. Likewise, the tissue-contacting portion and proximal extension portion of the second electrode plate are disposed in perpendicular planes relative to each other.

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 housing is configured to releasably couple to at least one of the shafts and an electrode assembly is associated with the disposable housing. The electrode assembly includes electrodes releasably coupleable 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 switch is configured to initiate delivery of electrosurgical energy from the source of electrosurgical energy to the electrodes. An actuation mechanism is configured to selectively advance the knife blade through the knife channel to cut tissue.

Abstract: An endoscopic forceps includes an elongate shaft defining an instrument axis. An end effector includes first and second jaw members each supporting an opposed sealing surface for clamping tissue. At least one of the jaw members is movable relative to the instrument axis such that the jaw members are movable between a first spaced-apart configuration and a second closed configuration for grasping tissue. A cutting instrument includes a reciprocating blade translatable relative to the sealing surfaces to sever tissue clamped between the jaw members. The reciprocating blade contacts an undersurface of at least one of the jaw members when the jaw members are in the second configuration to define a gap distance between the sealing surfaces. A handle adjacent the proximal end of the elongate shaft is operable to induce motion in the jaw members, and an actuator is operable to selectively translate the reciprocating blade.

Abstract: A forceps includes a pair of shafts each having a jaw member disposed at a distal end thereof. One (or both) of the shafts is moveable relative to the other about a pivot pin between a spaced-apart position and an approximated position to move the jaw members between an open position and a closed position. A knife assembly includes a knife blade mechanically keyed to the pivot pin and moveable between an initial position, wherein the knife blade is disposed within one of the jaw members, and an extended position, wherein the knife blade extends between the jaw members. An actuator arm(s) is mechanically keyed to the pivot pin and extends therefrom. The actuator arm(s) is moveable between an un-actuated position and an actuated position to rotate the pivot pin relative to the jaw members to move the knife blade between the initial position and the extended position.
