Abstract: A method of treating tissue includes clamping tissue between an ultrasonic blade and a jaw member and simultaneously: transmitting ultrasonic energy to the ultrasonic blade to vibrate the ultrasonic blade at a first blade velocity thereby heating the clamped tissue; and supplying electrosurgical energy, at a constant voltage, to the jaw member and the ultrasonic blade at different potentials such that the electrosurgical energy is conducted therebetween and through the clamped tissue to heat the clamped tissue. An impedance of the clamped tissue is monitored and the simultaneous transmission of ultrasonic energy and supply of electrosurgical energy is terminated and/or a notification is output once the clamped tissue is sealed, as indicated by the impedance of the clamped tissue being equal to or greater than a threshold impedance. Surgical instruments and end effectors thereof for treating tissue in this manner are also provided.

Abstract: An ultrasonic motion generator includes a non-resonant inverter, an ultrasonic transducer, and a comparator. The non-resonant inverter inverts direct current (DC) to alternating current (AC) having a first frequency.

The comparator automatically detects a deviation of the first frequency from a resonant frequency of the ultrasonic transducer based on motion current passing through the ultrasonic transducer and generates an output signal based on the deviation to drive the non-resonant inverter.
