  • Patent number: 10278772
    Abstract: An endoscopic bipolar forceps includes a housing and a shaft affixed to the housing. The shaft includes a longitudinal axis defined therethrough and a pair of jaw members attached to a distal end thereof. The forceps also includes a drive assembly for moving one of the jaw members relative to the other jaw member from a first position wherein the movable jaw members are disposed in spaced relation relative to each other to a second position wherein the jaw members are closer one another for manipulating tissue. A movable handle is included which is rotatable about a pivot to force a drive flange of the movable handle into mechanical cooperation with the drive assembly to move the jaw members from the open and closed positions. The pivot is located a fixed distance from the longitudinal axis and the drive flange is located generally along the longitudinal axis.

  • Publication number: 20180256191
    Abstract: The present disclosure is directed to a fluid cooled ultrasonic surgical instrument and related systems and methods of use therefor. In some embodiments, the disclosed ultrasonic surgical instrument is adapted for used within an insufflated cavity or pneumoperitoneum of a patient. The instrument includes a housing having an elongate shaft, a waveguide disposed at a distal end of the shaft, a coolant inlet port defined in an outer surface of the housing, and a coolant pump disposed within the housing and configured to move coolant from the coolant inlet port to the waveguide. During use, insufflation gas from within the pneumoperitoneum is drawn into the instrument shaft by the coolant pump, and blown over the waveguide to provide cooling. The delivery of ultrasonic energy and activation of the pump may be controlled by a processor in response to user input and waveguide temperature.
