Abstract: An apparatus includes a shaft assembly and an end effector. The shaft assembly includes a first coupling member and a second coupling member. The first coupling member and the second coupling member are configured to flex toward each other from a first position to a second position. The first coupling member and the second coupling member define a pivot axis in the first position. The end effector includes an ultrasonic blade and a clamp arm. The clamp arm is configured to couple or decouple with the shaft assembly when the first coupling member and the second coupling member are in the second position. The clamp arm is configured to pivot toward and away the ultrasonic blade about the pivot axis when the first coupling member and the second coupling member are in the first position.

Abstract: A surgical instrument is disclosed including an end effector, a generator configured to deliver adaptive energy, a mode selector switch having a plurality of surgical modes, a closure switch configured to control the end effector, and a counter configured to count a number of closure switch activations. The surgical instrument is configured to communicate a selected surgical mode of the mode selector switch and the number of closure switch activations from the counter to the generator. The surgical instrument is configured to receive the adaptive energy from the generator based on the selected surgical mode and the number of closure switch activations. The generator is configured to deliver the adaptive energy to the surgical instrument closer to a start of an activation cycle for the selected surgical mode as the number of closure switch activations increases.

Abstract: 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.

Abstract: An ultrasonic instrument includes a body and a shaft assembly extending distally from the body. The shaft assembly includes an acoustic waveguide. The instrument further includes an end effector including an ultrasonic blade. The ultrasonic blade is in acoustic communication with the acoustic waveguide. The instrument further includes a sensor configured to sense at least one characteristic of the shaft assembly and/or the end effector. The end effector is configured to be activated at varying power levels based on the at least one characteristic sensed by the sensor.

Abstract: A surgical apparatus comprises a body, a shaft assembly, and an end effector. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with an ultrasonic transducer via an acoustic waveguide that extends through the shaft assembly. The clamp arm is configured to pivot about a first pivot point toward and away from the ultrasonic blade along a first angular path from a first position to a second position to thereby provide a tissue sealing mode of operation. The clamp arm is further configured to pivot about a second pivot point toward and away from the ultrasonic blade along second angular path from the second position to a third position to thereby provide a tissue cutting and sealing mode of operation. The second pivot point is proximal to the first pivot point.

Abstract: 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

Abstract: An ultrasonic instrument comprises a body, a shaft assembly, an ultrasonic blade, and a pivoting member. The shaft assembly extends distally from the body. The ultrasonic blade is positioned distal to the shaft assembly. The pivoting member is pivotable with respect to the blade from an open position to a closed position to thereby clamp tissue between the pivoting member and the blade. One or both of the shaft assembly or the pivoting member comprise a guide feature. The guide feature is configured to provide lateral alignment of the distal portion of the pivoting member with the blade as the pivoting member is pivoted to the closed position.
