摘要： Various systems and methods for determining the composition of tissue via an ultrasonic surgical instrument are disclosed. A control circuit can be configured to monitor the change in resonant frequency of an ultrasonic electromechanical system of the ultrasonic surgical instrument as the ultrasonic blade oscillates against a tissue and determine the composition of the tissue accordingly. In some aspects, the control circuit can be configured to modify the operation of the ultrasonic electromechanical system or other operational parameters of the ultrasonic surgical instrument according to the detected tissue composition.

摘要： An ultrasonic device may include an ultrasonic system including a transducer coupled to an ultrasonic blade, A method of delivering energy to the device may include sensing a vessel contacting the blade, identifying that the vessel is calcified, and generating a warning. In some aspects, the method further includes disabling one or more activation functions of the blade. In another aspect, the method further includes generating a message to apply compression to the vessel for a predetermined period, disabling activation functions of the blade during compression, and enabling activation functions after the expiration of the compression period. In yet another aspect, the method includes applying a compressive clamp force to the calcified vessel by driving a clamp arm toward the blade, disabling activation functions of the blade during compression, and enabling the activation functions after adjusting the compressive force. An ultrasonic surgical instrument may effect the method.

摘要： A method of determining instability of an ultrasonic blade includes monitoring a phase angle ϕ between voltage Vg(t) and current Ig(t) signals applied to an ultrasonic transducer, coupled to an ultrasonic blade via an ultrasonic waveguide, inferring the blade temperature based on the phase angle ϕ, comparing the inferred temperature to an ultrasonic blade instability trigger point threshold, and adjusting a power level applied to the ultrasonic transducer to modulate the temperature of the blade. The method may also include determining a frequency/temperature relationship of an ultrasonic blade that exhibits a displacement or modal instability and compensating for a thermal induced instability of the ultrasonic blade. The method may be implemented in an ultrasonic surgical instrument or by a control circuit in a power generator for the ultrasonic surgical instrument.

摘要： A method of ultrasonic sealing includes activating an ultrasonic blade temperature sensing, measuring a first resonant frequency of an ultrasonic electromechanical system that includes a transducer coupled to the blade via a waveguide, making a first comparison between the measured first resonant frequency and a first predetermined resonant frequency, and adjusting a power level applied to the transducer based on the first comparison. The first predetermined frequency may correspond to an optimal tissue coagulation temperature. The method may further include measuring a second resonant frequency of the system, making a second comparison between the measured second frequency and a second predetermined frequency, and adjusting the power level based on the second comparison. The second predetermined frequency may correspond a melting point temperature of a clamp arm pad. An ultrasonic instrument and a generator may implement the method.

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.

摘要： Various systems and methods for determining the state of an ultrasonic electromechanical system are disclosed. A control circuit can be configured to monitor the change in resonant frequency of an ultrasonic electromechanical system of the ultrasonic surgical instrument as the ultrasonic blade oscillates and determine the state or change in state of the ultrasonic electromechanical system accordingly. The change in state of the ultrasonic electromechanical system can include, for example, the change in temperature of the system. In some aspects, the control circuit can be configured to modify the operation of the ultrasonic electromechanical system or other operational parameters of the ultrasonic surgical instrument according to the state or change in state of the system.

摘要： A generator, ultrasonic device, and method of determining a temperature of an ultrasonic blade are disclosed. A control circuit coupled to a memory determines an actual resonant frequency of an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade by an ultrasonic waveguide. The actual resonant frequency is correlated to an actual temperature of the ultrasonic blade. The control circuit retrieves from the memory a reference resonant frequency of the ultrasonic electromechanical system. The reference resonant frequency is correlated to a reference temperature of the ultrasonic blade. The control circuit then infers the temperature of the ultrasonic blade based on the difference between the actual resonant frequency and the reference resonant frequency.
