Abstract: An ultrasonic instrument includes a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body. The shaft assembly includes an acoustic waveguide configured to acoustically couple with an ultrasonic transducer. The end effector includes an ultrasonic blade, a clamp arm and a clamp pad. The ultrasonic blade is in acoustic communication with the waveguide. The clamp arm is pivotally coupled with the shaft assembly. The clamp pad is configured to removably couple with the clamp arm while the clamp arm is pivotally coupled to the shaft assembly.

Abstract: Aspects of the present disclosure include various ultrasonic surgical instruments. At least one disclosed surgical instrument includes a waveguide including a blade and a transducer base plate. The transducer base plate may be coupled to the waveguide to define a tapered joint at an interface between the waveguide and the transducer base plate. The transducer base plate may include first and second sides defining corresponding first and second flat faces configured to receive first and second piezoelectric elements. The first and second piezoelectric elements are configured to operate in a D31 mode.

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: An apparatus for operating on tissue includes a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body and includes an acoustic waveguide. The waveguide is configured to acoustically couple with an ultrasonic transducer. The end effector includes an ultrasonic blade, a clamp arm, and a clamp pad. The blade is in acoustic communication with the waveguide. The clamp arm is configured to pivot about a first pivot point toward and away from the ultrasonic blade and includes a coupling feature. The clamp pad is selectively attachable to the blade to acoustically isolate the clamp arm from the ultrasonic blade. The coupling feature of the clamp arm is configured to provide a snap fit between the clamp pad and the clamp arm and thereby permit manipulation of the clamp pad for removal of the clamp pad from the clamp arm.

Abstract: Various forms are directed to systems and methods for dissection and coagulation of tissue. A surgical instrument includes an end effector configured to dissect and seal tissue at a distal end thereof, and a selector switch having a plurality of surgical modes. A generator is electrically coupled to the surgical instrument and is configured to deliver energy to the end effector. Each surgical mode of the selector switch corresponds to an algorithm for controlling the power delivered from the generator to the end effector, and each algorithm corresponding to the plurality of surgical modes is configured to allow a user to control the power output level of the generator.

Abstract: A surgical instrument includes an ultrasonic waveguide extending through a body assembly. An ultrasonic blade connects to the ultrasonic waveguide. A clamp arm assembly of the surgical instrument is able to move from an opened position for receiving a tissue toward a closed position for clamping the tissue. The clamp arm assembly includes a clamp body and a clamp pad facing the ultrasonic blade. A clamp arm actuator of the surgical instrument is able to move from a first position toward a second position to direct the clamp arm assembly from the opened position toward the closed position. A modular coupling of the surgical instrument connects to the clamp pad such that at least the clamp pad can be disconnected relative to the ultrasonic blade for replacement thereof.

Abstract: An end effector includes first and second jaws movable between open and closed positions, a guide track defined in the second jaw, and a cutting element extendable into the guide track and longitudinally movable within the guide track. A retention feature is positioned within the guide track and operatively couples the cutting element to a drive rod. The drive rod is actuatable to move the cutting element within the guide track, and the retention feature is larger than a width of an opening to the guide track such that the retention feature is retained within the guide track as the cutting element moves.

Abstract: A surgical apparatus comprises a body, a user input feature, a shaft assembly, an end effector, and a blade cooling system. The end effector comprises a clamp arm and an ultrasonic blade that may be coupled with an ultrasonic transducer. The clamp arm is configured to pivot toward and away from the ultrasonic blade. The cooling system is operable to deliver liquid coolant to the ultrasonic blade to thereby cool the ultrasonic blade. The user input feature is operable to both actuate the clamp arm and actuate the cooling system.

Abstract: A robotic surgical system is disclosed including an end effector movable relative to a tissue of a patient. The robotic surgical system further includes a control circuit configured to determine a distance between the end effector and the tissue and cause the end effector to be transitioned between a locked configuration and an unlocked configuration based on the distance.
