SURGICAL SYSTEM WITH TECHNIQUES ADAPTABLE TO THE USER AND EMPLOYING MULTIPLE ENERGY MODALITIES BASED ON TISSUE PARAMETERS. The present disclosure takes various forms relating to systems and methods for tissue dissection and coagulation. A method for detecting a short circuit in a surgical system configured to deliver radiofrequency energy and ultrasonic energy to a surgical target site includes delivering radiofrequency (RF) energy to an electrode of a surgical instrument, transitioning from delivery of RF energy to deliver ultrasonic energy to an ultrasonic blade of the surgical instrument, provide an exploratory ultrasonic pulse to the ultrasonic blade, measure an ultrasonic property of tissue engaged by the surgical instrument, where the ultrasonic property is associated with the ultrasonic pulse thorium, determine whether the ultrasonic property is consistent with low impedance tissue behavior, and supply ultrasonic energy to the ultrasonic blade to cut the tissue by determining that the measured ultrasonic property is consistent with the ultrasonic energy that is applied to the low impedance tissue. |
