    Abstract: An articulating surgical end effector includes an expandable pivot defined at a distal end of an ultrasonic waveguide, a socket at least partially receiving the expandable pivot within an interior volume thereof, and a blade extending distally from the socket. The socket is configured to articulate about the expandable pivot in any direction, and the expandable pivot and socket together are configured to enable ultrasonic energy transmission through the ultrasonic waveguide to the blade in any articulated position of the socket relative to the expandable pivot.

    Abstract: An ultrasonic surgical instrument includes a transducer configured to produce a first mode of ultrasonic energy and a waveguide coupled to the transducer. The waveguide includes a proximal body portion coupled to and extending distally from the transducer. The proximal body portion is configured to receive the first mode of ultrasonic energy from the transducer for transmission therealong. The waveguide further includes a distal body portion, a blade extending distally from the distal body portion, and an articulation portion interconnecting the proximal and distal body portions. The articulation portion is configured to enable articulation of the distal body portion relative to the proximal body portion, to receive the first mode of ultrasonic energy from the proximal body portion, convert the first mode of ultrasonic energy into a second mode of ultrasonic energy, and transmit the second mode of ultrasonic energy along the distal body portion to the blade.

    IPC: A61B18/14

    Abstract: An end effector assembly for a surgical instrument includes first and second jaw members each including a jaw housing, an electrically-conductive tissue-treatment plate, and a longitudinally-extending channel. The first and/or second jaw member is movable relative to the other between a spaced-apart position and an approximated position. A cutting mechanism is disposed at least partially within the second jaw member. The cutting mechanism may include an inflatable bladder, a fluid line coupled to the inflatable bladder, and a knife coupled to the inflatable bladder. The cutting mechanism may alternatively include a fluid line, a knife, and a sealing member that defines a variable-volume sealed chamber within the longitudinally-extending channel of the second jaw member. The cutting mechanism may alternatively include at least one electromagnet, at least one electrical wire coupled to the at least one electromagnet, and a knife operably coupled to the at least one electromagnet.

    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 for forming an end-to-end anastomosis includes first and second handles each supporting a shaft at a distal end thereof. The proximal ends of each shaft are coupled about a pivot such that movement of the handles correspondingly moves the distal ends of each shaft. A release mechanism is included that is actuatable to pivot a pair of bifurcated legs of each shaft between a first position for receiving first and second vessels and a second position that facilitate release of the respective first and second vessels. First and second posts are supported on each distal end and are configured to support an end of the respective first and second vessels thereon. The posts are adapted to connect to an electrical generator for communicating energy through each end of each respective first and second vessel to form an anastomotic seal.
