Abstract
An ultrasonic surgical instrument that is configured to permit selective positioning of the relative distance between an end effector for cutting and coagulating tissue and a power actuation switch that is carried by the instrument for selectively energizing the end effector. In one instance, the end effector is able to change position relative to the actuation switch, alternatively, the actuation switch moves relative to the end effector, and still further, both the end effector and the actuation switch are capable of moving relative to each other.
