Abstract: An interchangeable tool assembly is disclosed. The interchangeable tool assembly includes a first jaw configured to support a staple cartridge during a first time period and a radio-frequency cartridge during a second time period. A second jaw is coupled to the first jaw. A surface of the second jaw defines a plurality of staple forming pockets configured to form staples driven from the staple cartridge. An electrically insulative material covers segments of the surface of the second jaw other than the staple forming pockets. The staple forming pockets define at least one return path for radio-frequency energy delivered by the radio-frequency cartridge.

Abstract: A surgical instrument that includes first and second jaws that are movably coupled together to move between an open and a closed position. The first jaw includes a first proximal end, a first distal tip, and a first jaw midpoint between the first proximal end and the first distal tip. The second jaw includes a second proximal end and a second distal tip. The first jaw includes a first alignment feature that is distal to the first jaw midpoint and is configured to engage a corresponding portion of the second jaw when the first and second jaws are moved to the closed position to align the first distal tip with the second distal tip.

Abstract: An end-effector is disclosed including an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator and a clamp arm including a clamp jaw and a cantilever electrode fixed to the clamp jaw. The cantilever electrode is configured to electrically couple to an opposite pole of the electrical generator. The clamp arm may include an I-beam shaped clamp arm pad and the cantilever electrode is disposed between the I-beam. The clamp jaw, the cantilever electrode, and the clamp arm pad may define recesses along a length coinciding with the ultrasonic blade. The clamp arm pad may be fixed to the clamp jaw and disposed between the clamp jaw and the cantilever electrode and may extend beyond the surface of the cantilever electrode. The clamp arm may include a stationary gap setting pad and movable floating gap setting pads.

Abstract: Disclosed is an ultrasonic surgical instrument comprising a transducer base plate, first and second piezoelectric elements positioned on opposite faces of the transducer base plate. The transducer base plate is coupled to a waveguide. The waveguide is electrically coupled to the first and second piezoelectric elements by a conductive adhesive. The first and second piezoelectric elements are electrically coupled to an ultrasonic signal generator through an electrode. A thermal conductor conducts thermal energy away from the first and second piezoelectric elements. Also disclosed is a method of fabricating such an ultrasonic surgical instrument.
