    Abstract: A surgical instrument includes a housing having an elongated body extending distally therefrom. The elongated body defines a first articulating portion and a second articulating portion. The elongated body defines a lumen therein. An end effector is supported at a distal end portion of the elongated body. A flexible waveguide extends through the lumen of the elongated body. A proximal end portion of the flexible waveguide connects to an ultrasonic transducer. A distal end portion of the flexible waveguide is connected with the end effector. the flexible waveguide defines a first articulating portion having a narrower thickness than a thickness of other portions of the flexible waveguide and a second articulating portion having a narrower thickness than a thickness of other portions of the flexible waveguide.

    Abstract: An ultrasonic end effector includes a substantially cylindrical blade and a jaw including a structural body and a jaw liner. The jaw is movable from an open to a clamping position, wherein the blade-facing surface of the jaw liner opposes the blade with the first and second blade-facing surfaces of the structural body disposed on either side of the jaw liner and the blade. The blade defines a first longitudinal axis and a first radius, the first and second blade-facing surfaces of the structural body cooperate to define a second radius centered on a second longitudinal axis, and the blade-facing surface of the jaw liner defines a third radius centered on a third longitudinal axis. The first radius and the second radius of curvature are different from one another.

    Abstract: An ultrasonic surgical instrument includes a housing, an elongated shaft extending distally from the housing, an end effector extending distally from the elongated shaft, and a transducer assembly disposed at least partially within the elongated shaft. The end effector includes a jaw and an ultrasonic blade. The jaw is configured to pivot relative to the ultrasonic blade from an open position to a clamping position for clamping tissue therebetween. The transducer assembly is distally-spaced from the housing and includes proximal and distal transducers interconnected by a connector. The ultrasonic blade is connected to the distal transducer such that ultrasonic energy produced by the proximal transducer is transmitted along the connector and the distal transducer to the ultrasonic blade and such that ultrasonic energy produced by the distal transducer is transmitted to the ultrasonic blade.

    Abstract: A jaw member of a surgical instrument includes a structural body including a tissue-facing surface having an elongated opening defined therethrough and defining an internal cavity in communication with the elongated opening. A jaw liner of a material that is not conducive to molding includes an internal portion substantially filling the internal cavity and extending to the elongated opening. A method of manufacturing a jaw member of a surgical instrument includes preparing a material, forging the material into an internal cavity defined within a structural body of a jaw member, and setting the material such that the material substantially fills the internal cavity and is retained therein thereby forming a jaw liner of the jaw member.

    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 disposed on either side of the insulative tissue-contacting surface. A second jaw member includes an ultrasonic blade body positioned to oppose the insulative tissue-contacting surface of the first jaw member. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to apply a first grasping force to tissue disposed therebetween. A slider is movable, independent of the first jaw member, between a retracted position, wherein the slider is disposed proximally of the first and second jaw members, and an extended position, wherein the slider extends about the first jaw member and urges the first jaw member from the approximated position further towards the second jaw member to apply a second, greater grasping force to tissue.

    Abstract: A method for operating a surgical device, includes: determining whether a switch has transitioned from a first condition, corresponding to a first operating mode, to a second condition, corresponding to a second operating mode; when it is determined that the switch has transitioned from the first condition to the second condition: maintaining the first operating mode for a pre-determined time; in a case where the switch remains in the second condition throughout the pre-determined time, switching to the second operating mode after expiration of the pre-determined time; and when the switch returns to the first condition during the pre-determined time, maintaining the first operating mode after expiration of the pre-determined time.
