Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.

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 ultrasonic instrument includes a shaft assembly and an end effector having an ultrasonic blade, a clamp arm, and a clamp pad. 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. The clamp arm includes a mortise and a pair of support gussets. The clamp pad includes a tenon and a pair of resilient projections where the tenon engages the mortise of the clamp arm and the projections contact the support gussets of the clamp arm.

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 surgical instrument includes a shaft assembly and an articulation control assembly. The shaft assembly includes an articulation section that is configured to deflect a distal end portion from the longitudinal axis. The articulation control assembly includes an articulation control member and a transmission assembly. The articulation control member is rotatably mounted relative to the shaft assembly. The transmission assembly is operatively connected between the articulation control member and the articulation section of the shaft assembly. The transmission assembly is configured to transmit selective manipulation of the articulation control member to the articulation section and selectively actuate the articulation section. The articulation control assembly is configured to lock without selective manipulation of the articulation control member to thereby inhibit actuation of the articulation section and unlock with selective manipulation of the articulation control member to thereby actuate the articulation section.

Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, an articulation drive assembly, and a locking feature. The shaft extends distally from the body assembly. The waveguide comprises a flexible portion. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis of the shaft. The articulation drive assembly comprises an actuator. The actuator is movable relative to the body assembly to drive articulation of the articulation section. The locking feature is in communication with the actuator. The locking feature is movable between an unlocked state and a locked state. The locking feature is configured to permit movement of the actuator relative to the body assembly in the unlocked state. The locking feature is configured to prevent movement of the actuator relative to the body assembly in the locked state.

Abstract: A variety of methods for managing a re-usable ultrasonic medical device may include a medical device control module capable of receiving functional data from a user assembled or reassembled ultrasonic medical device, and notifying the user if a value of the functional data lies within an acceptance range. If the value of the functional data does not lie within the acceptance range, the control module may prompt a user to reassemble the device or to clean or replace one or more components thereof. The functional data may relate to a clamp force of a jaw assembly, an impedance or resonant frequency value of an ultrasonic blade, or a mechanical displacement value of one or more moving components of the device.

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.
