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: 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: 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: An ultrasonic instrument for use during a surgical procedure includes a body, a shaft assembly, an ultrasonic blade, and an actuation assembly. The body is configured to receive an ultrasonic transducer for selectively generating a first or a second predetermined oscillation. The shaft assembly projects from the body and includes an acoustic waveguide connected to the ultrasonic blade. The actuation assembly includes an activator ring and an activation mechanism. The activator ring is selectively movable along the body such that the activator ring is accessible to be gripped by an operator around an entirety of an outer circumferential surface of the activator ring. The activation mechanism is connected to the activator ring such that the activation mechanism selectively moves along the body in conjunction with the activator ring. At least a portion of the activation mechanism is configured to selectively direct the ultrasonic transducer to oscillate the ultrasonic blade.

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.
