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 disclsoed. 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 is 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： A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

摘要： An ultrasonic device may include an electromechanical system defined by a resonant frequency and further include an ultrasonic transducer coupled to an ultrasonic blade. The device may be composed of two or more components, one of which is reusable and one of which is disposable. A method of detecting a proper installation of the components may include determining a spectroscopy signature of the blade coupled to the transducer, comparing the signature to a reference signature, determining an installation state of the components based on the comparison, and controlling a delivery of power to the transducer based on the comparison. The method may include enabling an operation of the device when the installation state of components is proper. The method may further include disabling the device when the installation state is not proper and generating a warning. The warning may be visible, audible, or tactile.

摘要： Various systems and methods for determining the state of an end effector of an ultrasonic surgical instrument are disclosed. A control circuit can be configured to measure a complex impedance of an ultrasonic electromechanical system including an ultrasonic blade and compare the measured complex impedance to reference complex impedance patterns that each correspond to a state of the end effector. Accordingly, the control circuit can further be configured to determine the state of the end effector according to which of the plurality of reference complex impedance patterns the measured complex impedance corresponds.
