  • Patent number: 11116532
    Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

  • Publication number: 20210259725
    Abstract: An ultrasonic surgical instrument and method of assembly with a predetermined alignment includes first and second modular assemblies and an electrical lockout. The first modular assembly includes at least a portion of an end effector configured to manipulate a tissue. The second modular assembly includes a transducer power circuit and an activation switch electrically connected to the transducer power circuit. The electrical lockout is electrically connected to the transducer power circuit and configured to inhibit the activation switch from powering the ultrasonic transducer with the first and second modular assemblies misaligned from the predetermined alignment such that the first and second modular assemblies are in a locked-out state. The electrical lockout is further configured to allow the activation switch to power the ultrasonic transducer with the first and second modular assemblies in the predetermined alignment such that the first and second modular assemblies are in an operational state.

  • Publication number: 20210059709
    Abstract: An ultrasonic surgical instrument and method of deflecting an end effector include an acoustic waveguide with a proximal waveguide body portion defining a longitudinal axis, a distal waveguide body portion having an ultrasonic blade distally projecting therefrom, and an articulation body portion extending between the proximal and distal waveguide body portions. The articulation body portion of the acoustic waveguide is configured to flex a first direction to thereby deflect the ultrasonic blade relative to the longitudinal axis and through a first plane. In addition, the articulation body portion of the acoustic waveguide is further configured to flex a second direction to thereby deflect the ultrasonic blade relative to the longitudinal axis and through a second plane. The second direction is different than the first direction such that the second plane is different than the first plane for multiplanar deflection of the ultrasonic blade relative to the longitudinal axis.

  • Publication number: 20210059708
    Abstract: A surgical instrument includes an end effector, a shaft assembly, and an axial location feature. The end effector includes an ultrasonic blade and a clamp arm that can move between an open and closed position. The shaft assembly includes a proximal shaft portion, an acoustic waveguide extending proximally from the ultrasonic blade, a distal shaft portion extending along a distal axis, and an articulation section interposed between the proximal shaft portion and the distal shaft portion. The articulation section can deflect the distal shaft portion and the end effector relative to the longitudinal axis between a non-deflected position and a deflected position.

  • Publication number: 20200268408
    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.
