Abstract: 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.

Abstract: 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.

Abstract: Various aspects of a generator, ultrasonic device, and method for estimating 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 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.

Abstract: 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.

Abstract: Systems, devices, and methods are operable to track usage of a surgical instrument and modify the performance of the surgical instrument based on the prior usage of the surgical instrument. Some surgical instruments are designed to have a limited service life beginning at their first use, or a limit to their overall usage in order to ensure safe use of the sensitive instruments. However, a lack of ability to track usage characteristics when the instrument is separated from an external power supply allows for user abuse and avoidance of such safety mechanisms. Adding a battery or capacitor to the instrument may allow for an ability to track usage when the instrument is separated from an external power supply. Implementing special user prompts, device use ratios, and device use half-life upon powering down of an instrument may additionally be used to prevent circumvention of safety features.

Abstract: A radio frequency (RF) instrument may include a method of classifying a tissue in live time. The method may include activating the instrument for a first period of time T1 when the RF instrument contacts the tissue, plotting at least three electrical parameters associated with the tissue to classify the tissue into distinct groups, and applying a classification algorithm to classify the tissue into a distinct group in live time. The parameters may include an initial impedance of the tissue, a minimum impedance of the tissue, and an amount of time that the impedance slope is ˜0. The instrument may collect the parameters during a predetermined amount of time, such as within the first 0.75 seconds of the activation of the device. The classification algorithm may include a support vector machine algorithm that may use a linear, polynomial, or radial basis set.

The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator. The clamp arm includes a clamp jaw and an electrode configured to electrically couple to an opposite pole of the electrical generator. In one configuration, the electrode is segmented. In another configuration, the ultrasonic blade includes electrically insulative material deposited on selected areas to prevent electrical shorting in the event of the ultrasonic blade contacts the electrode.

Abstract: A surgical instrument including a shaft including a distal portion and an articulatable portion is disclosed. The articulatable portion, positioned proximal to the distal portion, includes a plurality of joint members. A first articulation cable extends through each first channel of each of the plurality of joint members and a second articulation cable extends through each second channel of each of the plurality of joint members to the distal portion. The first and second articulation cables are transitionable between: (i) an unlocked state, where the first and second articulation cables are free to translate distally and proximally and the plurality of joint members are slidable relative to one another to pivot the distal portion away from a longitudinal axis, and (ii) a locked state, where translation of the first and second articulation cables is locked, causing a position of the distal portion relative to the longitudinal axis to be locked.
