    Abstract: A forceps includes first and second shaft members each having a jaw member disposed at a distal end thereof. One (or both) of the first and second jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. The first jaw member includes a jaw frame fixedly engaged to the first shaft member and a disposable jaw housing releasably engageable with the jaw frame. The disposable jaw housing includes a knife assembly disposed therein. The knife assembly includes a knife blade biased toward an initial position, wherein the knife blade is disposed within the jaw housing. The knife blade is moveable between the initial position and an extended position, wherein the knife blade extends at least partially from the jaw housing to cut tissue grasped between the first and second jaw members.

    Abstract: A forceps includes an end effector assembly having first and second jaw members. One (or both) of the first and second jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a jaw frame a disposable jaw housing and an elastomeric ring member. The disposable jaw housing is releasably engageable with the jaw frame. The elastomeric ring member is removably positionable about a distal end of the jaw housing. The elastomeric ring member is configured to define a gap distance between the first and second jaw members upon movement of the first and second jaw members to the approximated position.

    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 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 has electrodes releasably coupleable to the jaw members and adapted to connect to a source of electrosurgical energy to allow selective conduction of electrosurgical energy through tissue held therebetween to effect a tissue seal. An electrically conductive cutting element is disposed on at least one of the electrodes and is adapted to connect to the source of electrosurgical energy to allow selective conduction of electrosurgical energy through tissue held between the electrodes to effect a tissue cut.

    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: 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: An energizable surgical attachment is configured for positioning about a shaft of a surgical instrument. The energizable surgical attachment includes an outer sheath defining a lumen extending longitudinally through the outer sheath, an energizable rod member coupled to the outer sheath, a connector attachment electrically coupled to the energizable rod member, and at least one o-ring disposed within the lumen of the outer sheath. At least a portion of the energizable rod member extends distally from the distal end of the outer sheath. The o-ring(s) are configured to establish a fluid-tight seal between the outer sheath and the shaft of the surgical instrument and to bias the outer sheath towards a stationary position relative to the shaft of the surgical instrument.
