摘要： 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.

摘要： 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.

摘要： 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.

摘要： A surgical instrument configured to facilitate access to interior components thereof for cleaning and refurbishment purposes. The instrument includes a housing assembly, an elongated shaft assembly and an end effector. The housing assembly includes an actuator, and the elongated shaft assembly includes an interior control member operatively coupled to the actuator. The elongated shaft assembly also includes outer cover including first and second cover members and a hinge coupling the first and second cover members to one another such that the outer cover may be selectively moved between a closed configuration wherein the interior control member is enclosed within the outer cover and an open configuration wherein the interior control member is exposed. The end effector is supported at a distal end of the elongated shaft assembly, and is operatively associated with the interior control member.

摘要： A forceps includes an end effector assembly having first and second jaw members. Each jaw member includes a proximal flange having an inwardly-facing surface. The proximal flanges are coupled to one another for moving the jaw members relative to one another between a first position and a second position for grasping tissue therebetween. The inwardly-facing surfaces of the proximal flanges are disposed in abutting relation relative to one another. A knife is configured to move along a knife path defined along an outwardly-facing surface of one of the proximal flanges. The knife is movable between a retracted position and an extended position, wherein the knife extends between the jaw members to cut tissue grasped therebetween.

摘要： An end effector assembly having first and second jaw members is provided where one or both of the 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 an inwardly-facing surface having a slot defined therein and a wire having an insulative coating. A seal plate has at least one protrusion that is configured to be disposed in the slot. The at least one protrusion of the seal plate is configured to displace the insulative coating from the wire thereby forming an electrical connection therewith when the at least one protrusion is disposed in the slot.
