    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: A surgical instrument includes an ultrasonic transducer supported by a housing and an elongated assembly extending distally therefrom. The elongated assembly includes a jaw and a waveguide coupled to the transducer and defining a blade having upper and lower tissue-contacting surface and first and second lateral surfaces disposed therebetween that are coated with a material. The jaw is pivotable relative to the blade and includes a structural base having a backspan and first and second uprights extending from the backspan. The jaw further includes a jaw liner supported within the structural base and positioned to oppose the upper tissue-contacting surface with the first and second uprights disposed on either side of the blade. In an ultrasonic mode, ultrasonic energy produced by the transducer is transmitted along the waveguide to the blade. In an electrosurgical mode, electrosurgical energy is conducted between the blade and the first and second uprights.

    IPC: A61B17/32

    Abstract: An ultrasonic surgical system includes a waveguide defining first and second longitudinal lumens extending through at least a portion of a length of the waveguide. A distal transverse lumen is defined within the waveguide transversely through at least a portion of the waveguide to intersect and interconnect the first and second longitudinal lumens. First and second proximal transverse lumens extend from first and second proximal transverse apertures within the waveguide transversely through portions of the waveguide to intersect the first and second longitudinal lumens, respectively. Inflow and outflow conduits are fluidly coupled with the first and second proximal transverse apertures, respectively, to enable the inflow of fluid into the first longitudinal lumen and the outflow of fluid from the second longitudinal lumen, respectively.

    Abstract: An articulating ultrasonic surgical end effector includes a clevis, a transducer housing pivotably coupled to the clevis, an ultrasonic transducer disposed within the transducer housing, a waveguide extending distally from the ultrasonic transducer, an ultrasonic blade disposed at the distal end of the waveguide, a shaft extending distally from the transducer housing about at least a portion of the ultrasonic blade, and a clamp arm pivotably coupled to the shaft and movable relative to the ultrasonic blade between an open position and a clamping position. Ultrasonic energy produced by the ultrasonic transducer is transmitted along the waveguide to the ultrasonic blade for treating tissue therewith.
