In ultrasonic devices, what is the function of the passive jaw?

Explanation:
The passive jaw acts as the grasper and backstop. It grabs and compresses tissue so it sits firmly against the vibrating active blade, allowing the ultrasonic energy to cut and coagulate efficiently. This stable tissue apposition reduces slippage and helps protect nearby structures during transection. It does not perform suction, cutting, or irrigation—those functions come from other parts of the instrument or separate devices.
