Abstract: A surgical instrument end effector assembly includes a first jaw member defining an insulative tissue-contacting surface and first and second electrically-conductive tissue-contacting surfaces, and a second jaw member positioned including an ultrasonic blade body and defining at least one electrically-conductive tissue-contacting surface. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to grasp tissue therebetween. The second jaw member is movable relative to the first jaw member between a first configuration, to facilitate transmission of ultrasonic energy to tissue grasped between the first and second jaw members, and a second configuration, to facilitate conduction of electrosurgical energy through tissue grasped between the first and second jaw members.

Abstract: A forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to at least one of the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

Abstract: A surgical instrument includes an active electrode coupled to a source of electrosurgical energy. The active electrode includes a tissue-contacting surface on an exterior surface of the instrument such that the tissue-contacting surface of the active electrode may intimately engage tissue. A replacement electrode includes a tissue-contacting surface, and is located in an interior cavity of the instrument. A seal is formed between the active electrode and the interior cavity of the instrument such that the tissue-contacting-surface of the replacement electrode is isolated from contamination exposed to the exterior of the instrument. The active electrode is removable from the instrument to expose the tissue-contacting surface of the replacement electrode, and the replacement electrode is connectable to the source of electrosurgical energy when the active electrode is removed.

Abstract: A method for manufacturing an end effector assembly includes providing first and second jaw members moveable relative to one another about a pivot between a first, spaced-apart position and a second, approximated position. One of the first and second jaw members includes a cavity defined therein and the other of the first and second jaw members includes a stop member configured to be inserted into the cavity. A gap-setting gauge is grasped between the first and second jaw members to define a gap-distance between the jaw members equivalent to a thickness of the gap-setting gauge. The first and second jaw members are set such that the jaw members are prevented from approximation beyond the gap-distance.

Abstract: A surgical instrument includes an elongated shaft module and a handle module selectively separable from one another. The elongated shaft module includes an elongated shaft member and a pair of jaw members supported at a distal end of the elongated shaft member, at least one of the jaw members moveable relative to the other jaw member between open and closed positions. The handle module includes a housing including an opening extending longitudinally therethrough. The opening is dimensioned to permit passage of the pair of jaw members in the closed position. The handle module also includes a movable handle movable relative to the housing to move the pair of jaw members between open and closed positions, and a lock to secure the elongated shaft module in place within the housing.
