Abstract: A surgical instrument includes a slip-ring contact assembly. The slip-ring contact assembly includes an insulative housing defining a plurality of slots. A plurality of slip-ring contacts is operably supported in the insulative housing. Each slip-ring contact is configured to engage one or more electrical contacts formed circumferentially around a rotatable shaft of the surgical instrument. Each slip-ring contact includes a tang extending through a corresponding slot defined in the insulative housing and configured to be operably connected to an external wire connection. The plurality of slip-ring contacts is configured to allow unlimited rotation of the rotatable shaft while maintaining continuous electrical contact between each slip-ring contact and the corresponding electrical contact of the rotatable shaft.

Abstract: A method for treating tissue includes determining whether tissue is present between first and second jaw members. In a case where it is determined that tissue is present between the first and second jaw members, the method further includes determining whether activation has been initiated. In a case where it is determined that activation has been initiated, the method further includes supplying electrosurgical energy to the first and second jaw members to seal the tissue and, if it is determined that sealing is complete: stopping the supply of electrosurgical energy; activating a thermal cutting element to supply thermal energy to cut the sealed present tissue; determining if thermal cutting is complete; and, in a case where it is determined that the thermal cutting is complete, stopping and the supply of thermal energy.

Abstract: An ultrasonic surgical system includes an ultrasonic transducer configured to receive an electrical drive signal and produce ultrasonic mechanical motion that is output along an ultrasonic horn of the ultrasonic transducer. The ultrasonic horn defines a transverse cam slot. A blade extends from the ultrasonic horn. The blade receives the ultrasonic mechanical motion from the ultrasonic horn for treating tissue. A jaw member is movable relative to the blade between a spaced-apart position and an approximated position for clamping tissue. A cam pin is slidably disposed in the cam slot and is operably coupled to the jaw member. Slidably advancing the cam pin in the cam slot actuates the jaw member between the spaced-apart position and the approximated position.
