  • Patent number: 11694355
    Abstract: An augmented reality system is provided for use with a medical imaging scanner. The AR system obtains a digital image from a camera, and identifies a pose of a gantry of the medical imaging scanner based on content of the digital image. The gantry includes a movable C-arm supporting an imaging signal transmitter and a detector panel that are movable along an arc relative to a station. A range of motion of the movable C-arm along the arc is determined based on the pose. A graphical object is generated based on the range of motion and the pose, and is provided to a display device for display as an overlay relative to the medical imaging scanner.

  • Patent number: 11684437
    Abstract: Devices, systems, and methods for automatically exchanging a first end-effector on a robot arm with a second end-effector housed in a docking station. The first end-effector has a clamp that either engages or disengages the robot arm based upon an application of force of the robot arm onto the end-effector. The clamp has a spring loaded clip that disengages the first end-effector to allow the robot arm to move away from the released first end-effector. The robot arm is configured to automatically move to a port of a docking station housing the desired second end-effector using magnetic coils on the robot arm and the docking station to guide the robot arm.

  • Publication number: 20230148896
    Abstract: A method and system for determining an extent of matter removed from a targeted anatomical structure are disclosed. The method includes acquiring an initial representation of a targeted anatomical structure and then removing matter from the targeted anatomical structure. An instrument is then navigated within the targeted anatomical structure. The instrument includes a tracking array, and a relative position of the instrument within the targeted anatomical structure is determined by the tracking array. The method includes recording the relative position of the instrument within the targeted anatomical structure to determine a final representation of the targeted anatomical structure. Finally, the method includes determining an extent of matter removed from the targeted anatomical structure by comparing the initial representation of the targeted anatomical structure with the final representation of the targeted anatomical structure.

  • Publication number: 20230141953
    Abstract: A surgical robot system includes a surgical robot, a robot arm connected to such surgical robot, and an end-effector connected to the robot arm. A registration fixture is used in conjunction with various registration systems in the surgical robot system. Such registration systems likewise include a detachable base in the form of a detachable dynamic reference base, along with an associated mount, the dynamic reference base and mount having certain features which permit the dynamic reference base to be selectively attached, detached, and reattached at different phases of an operation, whether pre-operative or intra-operative, and such successive attachments are done without the dynamic reference base, and tracking markers associated therewith, losing registration. Related methods allow for the more efficient and effective performance of operations by virtue of the dynamic reference base maintaining its registration during attachments and reattachments.

  • Publication number: 20230079430
    Abstract: A medical imaging system includes a movable station having a C-arm, a collector, an X-ray beam emitter, and a controller. The collector is attached to a first end of the C-arm. The X-ray beam emitter faces the collector to emit an X-ray beam in a direction of the collector and is attached to a second end of the C-arm. The controller moves one of the X-ray beam emitter and the collector to a first offset position along a lateral axis orthogonal to the arc, and obtains a first set of images by rotating the collector and the X-ray beam emitter along the arc about a scanned volume. The controller moves the one of the X-ray beam emitter and the collector to a second offset position along the lateral axis, and obtains a second set of images. The controller combines the first and second set of images to generate a three-dimensional image of the scanned volume.

  • Publication number: 20230081244
    Abstract: A surgical system for computer assisted navigation during surgery, includes at least one processor that obtains a 3D radiological representation of a targeted anatomical structure of a patient and a set of fiducials of a registration fixture. The operations attempt to register locations of the set of fiducials in the 3D radiological representation to a 3D imaging space tracked by a camera tracking system. Based on determining one of the fiducials of the set has a location that was not successfully registered to the 3D imaging space, the operations display at least one view of the 3D radiological representation with a graphical overlay indicating the fiducial has not been successfully registered to the 3D imaging space, receive user-supplied location information identifying where the fiducial is located in the 3D radiological representation, and register the location of the fiducial to the 3D imaging space based on the user-supplied location information.
