摘要： Various aspects of a generator, ultrasonic device, and method for estimating and controlling a state of an end effector of an ultrasonic device are disclosed. The ultrasonic device includes an electromechanical ultrasonic system defined by a predetermined resonant frequency, including an ultrasonic transducer coupled to an ultrasonic blade. A control circuit measures a complex impedance of an ultrasonic transducer, wherein the complex impedance as defined as Z g ( t ) = V g ( t ) I g ( t ) ; The control circuit receives a complex impedance measurement data point and compares the complex impedance measurement data point to a data point in a reference complex impedance characteristic pattern. The control circuit then classifies the complex impedance measurement data point based on a result of the comparison analysis and assigns a state or condition of the end effector based on the result of the comparison analysis. The control circuit estimates the state of the end effector of the ultrasonic device and controls the state of the end effector of the ultrasonic device based on the estimated state.

摘要： An ultrasonic device may include an electromechanical ultrasonic system defined by a predetermined resonant frequency, the electromechanical ultrasonic system having an ultrasonic transducer coupled to an ultrasonic blade. A method of compensating power delivered to the ultrasonic device may include determining an articulation angle of an articulatable ultrasonic blade coupled to the ultrasonic transducer, adjusting a complex impedance of the ultrasonic transducer to compensate for power lost as a function of the articulation angle, and adjusting, a power applied to the ultrasonic transducer based on the articulation angle. The ultrasonic device may include a generator and a control circuit configured to effect the method.
