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.

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.
