Abstract

Various forms are directed to systems and methods for dissection and coagulation of tissue. A surgical instrument includes an end effector configured to dissect and seal tissue at a distal end thereof, and a generator that is electrically coupled to the surgical instrument and that is configured to deliver energy to the end effector. The surgical instrument includes an end effector configured to interact with a tissue at a distal end thereof, a generator electrically coupled to the surgical instrument and configured to deliver radio frequency (RF) energy and ultrasonic energy to the end effector to allow the end effector to interact with the tissue. The energy delivered to the end effector switches between RF energy and ultrasonic energy based on a determination of various factors such as tissue impedance.
