摘要： Various systems and methods for controlling the activation of energy surgical instruments are disclosed. An advance energy surgical instrument, such an electrosurgical instrument or an ultrasonic surgical instrument, can include one or more sensor assemblies for detecting the state or position of the end effector, arm, or other components of the surgical instrument. A control circuit can be configured to control the activation of the surgical instrument according to the state or position of the components of the surgical instrument.

摘要： An end effector of an electrosurgical device may include a discharge port, an aspiration port, two electrodes, and a diverter formed from a porous material. The diverter includes a matrix having voids to receive fluid from the discharge port. A releasable diverter assembly may include an assembly body configured to receive a pair of electrodes and a diverter composed of a porous material. A shaft assembly of an electrosurgical device may include two electrodes and two fluid cannulae. Each cannula may be disposed proximate to a surface of each of the electrodes. An end effector of an electrosurgical device may include a fluid discharge port, two electrodes, and a diverter disposed therebetween. A proximal edge of the diverter may form a secant line with respect to the end of the discharge port so that fluid emitted by the discharge port is disposed on a surface of the diverter.

摘要： A method of controlling the temperature of an ultrasonic blade includes applying a power level to an ultrasonic transducer to achieve a desired temperature at an ultrasonic blade coupled to the transducer via an ultrasonic waveguide, inferring a temperature of the blade based on a voltage Vg(t) signal and a current Ig(t) signal applied to the transducer, comparing the inferred temperature of the blade to a predetermined temperature; and adjusting the power level to the transducer based on the comparison. In some aspects, the method includes measuring a phase angle φ between the voltage Vg(t) and the current Ig(t) and inferring the temperature of the blade from the phase angle φ. In some aspects, the method includes measuring an impedance Zg(t) equal to a ratio of the voltage Vg(t) to the current Ig(t) and inferring the temperature of the blade from the impedance Zg(t).

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： A generator, ultrasonic device, and method for controlling 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. The control circuit controls the temperature of the ultrasonic blade based on the inferred temperature

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 end effector of an electrosurgical device may include a discharge port in communication with a first fluid path, an aspiration port in communication with a second fluid path, a first and second electrode, and a diverter in mechanical communication with the two electrodes. The diverter may receive, on its surface, a fluid emitted by the discharge port, and maintain a contact of the fluid with the first and second electrodes. The diverter may be further configured to prevent an aspiration, by the aspiration port, of the fluid on its surface. An electrosurgical device may include a source port in communication with a first fluid path, an evacuation port in communication with a second fluid path, a first and second electrode, and a housing. The device may include a shaft extending distally from the housing and the end effector as described above.
