  • Surgical instrument and method facilitating testing jaw force of the surgical instrument
    Patent number: 11806038
    Abstract: A method of testing a jaw force of an ultrasonic surgical instrument includes securing a blade of an end effector of the ultrasonic surgical instrument, clamping a jaw member of the end effector against the blade such that a sensor is received within a notch of the jaw member of the end effector, and measuring the jaw force of the end effector using the sensor.
    Type: Grant

    Date of Patent: November 7, 2023
    Assignee: Covidien LP
    Inventors: Matthias Lester, Jeremy P. Green, Kenneth E. Netzel
  • Jaw members for surgical instruments and surgical instruments incorporating the same
    Patent number: 11478268
    Abstract: A surgical instrument includes a support frame defining first and second non-circular apertures each defining at least one stop surface, and a jaw member having a structural body including a proximal flange portion and an elongated distal portion extending distally from the proximal flange portion. A jaw liner is engaged with the elongated distal portion and defines a tissue-contacting surface. A first and a second pivot boss protrude from opposite sides of the proximal flange portion and at least partially into the first and second non-circular apertures, respectively. Each pivot boss is non-circular and defines at least one stop surface configured to mate with the at least one stop surface of the respective non-circular aperture to stop rotation of the jaw member before the jaw liner is forced into contact with a blade from the surgical instrument. A surgical instrument including such a jaw member is also provided.
