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 selector switch having a plurality of surgical modes. A generator is electrically coupled to the surgical instrument and is configured to deliver energy to the end effector. Each surgical mode of the selector switch corresponds to an algorithm for controlling the power delivered from the generator to the end effector, and each algorithm corresponding to the plurality of surgical modes is configured to allow a user to control the power output level of the generator.
