    Abstract: A handle assembly includes a stationary handle having a first switch, a second switch, and a movable handle coupled thereto. The second switch is movable between a first position and a second position. The movable handle is movable relative to the stationary handle between a spaced position and an approximated position, in which the movable handle actuates the first switch. A portion of the movable handle is configured to contact the second switch when the second switch is in the first position to prevent the movable handle from actuating the first switch.

    Abstract: Surgical devices and related methods are disclosed. An example end effector for a surgical device may include a first jaw, a second jaw, and an articulating mechanism operable to move the first jaw between an open position, an intermediate position, and a closed position. An example articulating mechanism may include a first jaw mount coupled to the first jaw so that movement of the first jaw mount along a path causes rotation and translation of the first jaw mount and the first jaw. A pivotably mounted crank may operably couple an actuator linkage to the first jaw mount so that moving the actuator linkage rotates the crank, and rotation of the crank may move the first jaw mount along the path.

  • Publication number: 20200222113
    Abstract: A method for controlling a laparoscopic instrument. The method includes grasping a target utilizing the laparoscopic instrument by applying an initial trigger force to a trigger of the laparoscopic instrument, obtaining an updated trigger force based on a first pinch force, a second pinch force, and a state of the laparoscopic instrument, and grasping the target utilizing the laparoscopic instrument by applying the updated trigger force to the laparoscopic instrument. The first pinch force is applied to the target by an upper jaw of the laparoscopic instrument and the second pinch force is applied to the target by a lower jaw of the laparoscopic instrument.

  • Publication number: 20200222114
    Abstract: Methods and systems for ablating target tissue, such as in or along an airway, include modulation one of power and current of an a system to achieve a treatment output or parameter. Treatment outputs can include current, power, energy delivered, percent drop in impedance, an impedance-based ratio, a percent impedance slope, and/or an airway wall impedance. Power and/or current of the system can be varied, within certain maximum thresholds, such as power, current, and/or impedance thresholds, to achieve the desired output parameter target during some or all of the treatment time. The systems and methods reduce the variability of the treatment efficacy otherwise due to variability in electrical properties of patient tissue and/or electrode contact.

Biopsy locations are recorded to the guidance images during the first interventional procedure and the biopsy locations are mapped to the reference image to provide a planning image for use in a subsequent interventional procedure on the patient. In a subsequent interventional procedure, the prior planning image (124) may be registered to a current reference image (126) and the prior biopsy locations and prior and current targets are mapped to a guidance image acquired from a different imaging modality. Biopsy locations are then mapped to the guidance image (115) and mapped back to the current reference image.
