Abstract: Certain aspects relate to systems, methods, and techniques for correcting for uncommanded instrument roll. A method for adjusting a controller-feedback system in a medical instrument may comprise receiving data from a sensor at or near a distal end of the instrument, determining a tip frame of reference based on the data from the sensor, the tip frame of reference representing a current orientation of the distal end of the instrument, obtaining a desired frame of reference, determining an adjustment to a visual frame of reference or a control frame of reference based on the tip frame of reference and the desired frame of reference, and transforming the visual frame of reference or the control frame of reference.

Abstract: Co-manipulation robotic systems are described herein that may be used for assisting with laparoscopic surgical procedures. The co-manipulation robotic systems allow a surgeon to use commercially-available surgical tools while providing benefits associated with surgical robotics. Advantageously, the surgical tools may be seamlessly coupled to the robot arms using a disposable coupler while the reusable portions of the robot arm remain in a sterile drape. Further, the co-manipulation robotic system may operate in multiple modes to enhance usability and safety, while allowing the surgeon to position the instrument directly with the instrument handle and further maintain the desired position of the instrument using the robot arm.

Abstract: Certain aspects relate to systems and techniques for navigation-assisted medical devices. Some aspects relate to correlating features of depth information generated based on captured images of an anatomical luminal network with virtual features of depth information generated based on virtual images of a virtual representation of the anatomical luminal network in order to automatically determine aspects of a roll of a medical device within the luminal network.

Abstract: Navigation of an instrument within a luminal network can include image-based airway analysis and mapping. Image-based airway analysis can include detecting one or more airways in an image captured within a luminal network and determining branching information indicative of how the current airway in which the image is captured branches into the detected “child” airways. Image-based airway mapping can include mapping the one or more detected airways to corresponding expected airways of the luminal network in the preoperative model.

Abstract: A surgical robotic system automatically calibrates tubular and flexible surgical tools such as endoscopes. By compensating for unideal behavior of an endoscope, the surgical robotic system can accurately model motions of the endoscope and navigate the endoscope while performing a surgical procedure on a patient. During calibration, the surgical robotic system moves the endoscope to a target position and receives data describing an actual position and/or orientation of the endoscope. The surgical robotic system determines gain values based at least on the discrepancy between the target position and the actual position. The endoscope can include tubular components referred to as a sheath and leader. An instrument device manipulator of the surgical robotic system actuates pull wires coupled to the sheath and/or the leader, which causes the endoscope to articulate.

Abstract: Provided are systems and methods for displaying an estimated location of an instrument. In one aspect, the method includes determining a first location of the instrument based on first location data generated by a set of one or more location sensors for the instrument, the first location data corresponding to a first time period, and after the first time period, receiving a user command to move the instrument during a second time period. The method also includes estimating a second location of the instrument based on the first location and the received user command, the estimated second location corresponding to the second time period, and confirming the estimated second location based on second location data generated by the set of location sensors. The method further includes causing the estimated second location to be displayed prior to the confirmation of the estimated second location.

Abstract: Provided are systems and methods for path-based navigation of tubular networks. In one aspect, the method includes receiving location data from at least one of a set of location sensors and a set of robot command inputs, the location data being indicative of a location of an instrument configured to be driven through a luminal network. The method also includes determining a first estimate of the location of the instrument at a first time based on the location data, determining a second estimate of the location of the instrument at the first time based on the path, and determining the location of the instrument at the first time based on the first estimate and the second estimate.

Abstract: Provided are robotic systems and methods for navigation of luminal network that detect physiological noise. In one aspect, the system includes a set of one or more processors configured to receive first and second image data from an image sensor located on an instrument, detect a set of one or more points of interest the first image data, and identify a set of first locations and a set of second location respectively corresponding to the set of points in the first and second image data. The set of processors are further configured to, based on the set of first locations and the set of second locations, detect a change of location of the instrument within a luminal network caused by movement of the luminal network relative to the instrument based on the set of first locations and the set of second locations.

Abstract: Systems and methods for estimating instrument location are described. The methods and systems can obtain a first motion estimate based on robotic data and a second motion estimate based on position sensor data. The methods and systems can determine a motion estimate disparity based on a comparison of the first and second motion estimates. Based on the motion estimate disparity, the methods and systems can update a weighting factor for a location derivable from the robotic data or a weighting factor for a location derivable from the position sensor data. Based on the updated weighting factor, the methods and systems can determine a location/position estimate for the instrument. The methods and systems can provide increased accuracy for a position estimate in cases where the instrument experiences buckling or hysteresis.
