Abstract: An electrosurgical system for sealing and cutting tissue includes an electrosurgical signal generator sealing stage to provide an AC sealing signal on a set of sealing electrodes, an electrosurgical signal generator cutting stage to provide an AC cutting signal on a set of cutting electrodes, and one or more controllers configured to control the electrosurgical signal generator sealing stage and the electrosurgical signal generator cutting stage. The set of sealing electrodes and the set of cutting electrodes share at least one electrode in common. The set of sealing electrodes and the set of cutting electrodes are coupled to a plurality of surfaces positioned on first and second jaws of an end effector. In some embodiments, the AC sealing signal and the AC cutting signal are in-phase.
