Various ultrasonic instruments are disclosed. The ultrasonic instruments include structures configured to indicate the cutting length of the instruments, detect when grasped tissue has extended beyond the cutting length of the instrument, and prevent tissue from extending beyond the cutting length. Several techniques for each types of structures are disclosed.
Claims15
An ultrasonic surgical instrument comprising:
- an end effector;
- a jaw movable relative to the end effector between a jaw open position and a jaw closed position;
- a transducer assembly comprising at least two piezoelectric elements configured to ultrasonically oscillate the end effector;
- an indicium coextensive with a portion of the jaw overlying the end effector;
- a first arm;
- wherein the jaw is disposed at a distal end of the first arm;
- a second arm pivotably connected to the first arm;
- wherein the end effector is disposed at a distal end of the second arm;
- and
- a bar member extending from the second arm through the first arm at a position proximal to the jaw, the bar member comprising a curvature corresponding to a rotational arc of the first arm.
