Abstract
An ultrasonic surgical instrument and method of sealing a tissue includes measuring a first measured termination parameter with a controller and terminating an ultrasonic energy and an RF energy when the first measured termination parameter reaches a set one of a first smaller tissue predetermined termination parameter or a first larger tissue predetermined termination parameter to thereby inhibit transecting the tissue. The ultrasonic surgical instrument further includes an end effector having an ultrasonic blade, an RF electrode, and a controller. The controller operatively connects to the ultrasonic blade and the RF electrode and is configured to terminate the ultrasonic energy and the RF energy when the first measured termination parameter reaches the set one of the first smaller tissue predetermined termination parameter or the first larger tissue predetermined termination parameter to thereby inhibit transecting the tissue.
