  • Patent number: 10959748
    Abstract: An ultrasonic instrument comprises an ultrasonic transducer, an acoustic waveguide, and an ultrasonic blade. The blade includes a pair of obliquely extending edges. The obliquely extending edges diverge away from the longitudinal axis of the waveguide and away from each other along respective paths extending distally in relation to the waveguide. A distal portion of the blade is wider than a proximal portion of the blade along a plane. The blade further includes a curved distal edge and several laterally presented surfaces. The laterally presented surfaces may provide combinations of concave and convex curvatures. The laterally presented surfaces may be angled and/or curved along one or more orthogonal planes associated with the longitudinal axis of the waveguide.

  • Patent number: 10959769
    Abstract: A surgical instrument includes a rotatable electrical coupling assembly having a first part and a second part that electrically couple and rotate relative to each other. The second part is carried by and rotates with a tube collar coupled to a transducer. A portion of the transducer is inserted through an aperture of the second part, but does not contact the second part. The first part of the assembly may electrically couple to the second part via pogo pins, brush contacts, or ball bearings. Alternatively, the first part may comprise conductive channels formed in the casing. The second part may comprise a rotatable drum with a conductive trace. In some versions, one or more components may comprise MID components. In another version, the rotatable electrical coupling assembly comprises a rotatable PC board and brush contact. Further still, a circuit board may be provided with the transducer inside a transducer casing.

  • Patent number: 10639058
    Abstract: An ultrasonic element comprises an ultrasonic transducer and a head or blade. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The head or blade is in acoustic communication with the ultrasonic transducer such that the ultrasonic transducer is operable to drive the ultrasonic blade to vibrate ultrasonically. The head or blade has a curved distal face. The curved distal face defines a proximally extending concave curve. The transducer and head or blade may be driven using a control logic that is configured to cause the ultrasonic transducer to generate a first vibration set followed by a second vibration set. The first vibration set is configured to generate microbubbles in a fluid. The second vibration set is configured to grow microbubbles generated by the first vibration set. The control logic may provide a pause between the first vibration set and the second vibration set.

  • Patent number: 10607132
    Abstract: Techniques for managing device interaction between components of an inventory management system are described herein. User input associated with an operational state of the user device may be received at the user device and the user device may begin operating in a particular operational state. While operating in this state, the user device may transmit a wireless signal having a predetermined frequency. A mobile drive unit of the system, upon receipt of the wireless signal, may slow or stop. Operational state information may be transmitted to other components of the inventory management system indicating that the wireless signal is being transmitted and/or that the user device is operating in a particular operational state and a fault detection process may commence. The user device may provide an indication (e.g., via visual, audible, and/or haptic feedback devices) that the user device is operating in the particular operational state.

  • Publication number: 20190350616
    Abstract: An apparatus includes a shaft assembly, an ultrasonic blade, and a clamp assembly. The shaft assembly includes an acoustic waveguide operable to transmit ultrasonic vibrations to the blade. The clamp assembly includes a clamp arm pivotable toward and away from the blade about a pivot axis, to clamp tissue between the clamp arm and the blade. A rotation feature may provide rotation of the blade relative to the clamp arm about the longitudinal axis of the waveguide. Alternatively, the rotation feature may provide rotation of the clamp arm relative to the blade about the longitudinal axis. The rotation feature may be driven based on pivotal positioning of the clamp arm relative to the blade about the pivot axis. The rotation feature may selectively lock and unlock the angular position of either the blade or the clamp arm about the longitudinal axis at any of a number of predetermined angular positions.

  • Publication number: 20190239918
    Abstract: A surgical instrument comprises a body assembly and an end effector. The body assembly includes a control module, an orientation sensor communicatively coupled to the control module, and an energy component. The energy component is operable to activate the end effector at a plurality of energy settings. A storage device is communicatively coupled to the control module and includes a plurality of gesture profiles and corresponding energy settings. The control module is configured to set the energy setting of the energy component to a corresponding energy setting in response to a correlation between the output of the orientation sensor and a gesture profile. In some versions, the control module modifies the energy setting based upon output from a force sensor that measures the force on the end effector. The control module may also decrease the energy setting in response to an anomalous acceleration or deceleration detected by an accelerometer.

  • Patent number: 10278721
    Abstract: In various embodiments, a surgical instrument is provided that may comprise an end effector for performing a surgical procedure on tissue, for example. The end effector may comprise a pair of jaws, a closure beam, and a cutting member. The closure beam and the cutting member may be releasably coupled together by an interlocking member such that movement of the cutting member may cause the closure beam to also move relative to the jaws and cause the jaws to close and grip tissue, for example. The interlocking member may then unlock, allowing the cutting member to move through the gripped tissue and relative to the closure beam. Additionally, the cutting member and closure beam may be operated by a single trigger, which may be configured to provide haptic feedback to a user at various stages. Further, the jaws may be electrically energized to deliver energy and/or seal the gripped tissue.
