surgical system with user-adaptive techniques that employs multiple energy modalities based on tissue parameters

摘要

The present disclosure provides various forms referring to systems and methods for tissue dissection and coagulation. One method of detecting a short in a surgical system configured to apply radiofrequency energy and ultrasonic energy to a surgical target site includes providing radiofrequency (rf) energy to a surgical instrument electrode, performing the supply transition. RF energy for supplying ultrasonic energy to an ultrasonic blade of the surgical instrument, providing an exploratory ultrasonic pulse to the ultrasonic blade, measuring an ultrasonic property of the tissue engaged by the surgical instrument, in which the ultrasonic property is associated with the ultrasonic pulse. determine whether the ultrasonic property is consistent with low-impedance tissue behavior and provide ultrasonic energy to the ultrasonic blade to cut the tissue by determining that the measured ultrasonic property is consistent with the ultrasonic energy being applied. to low impedance tissue.
