Abstract: Surgical systems and methods for co-registering a virtual bone model and a physical bone involve a navigation system with a localizer to detect markers of a probe to track positions of the probe tip and a head-mounted device (HMD). The HMD enables the user to observe a real-world view of the physical bone and the probe on, or through, the HMD display. Controller(s) provide, on the HMD display, virtual landmarks combined with the real-world view of the physical bone, the landmarks being defined at virtual locations associated with the virtual bone model. The controller(s) capture, with the navigation system, positions of the probe tip in response to the probe tip contacting the surface of the physical bone at physical locations corresponding to the virtual locations of the landmarks. The controller(s) utilize the captured positions of the probe tip to co-register the virtual model bone and the physical bone.

Abstract: A mixed reality system includes a head-mounted device (HMD) having an HMD coordinate system and a camera to capture images. A localizer has a localizer coordinate system and position sensors supported by a housing to track a pose of a real object. Registration markers are configured to be recognized from the captured images of the camera of the HMD. The registration markers are disposed on the housing of the localizer in a predetermined spatial relationship with respect to the localizer coordinate system. At least one controller is configured to utilize the registration markers recognized from the captured images to register the localizer coordinate system and the HMD coordinate system.

Abstract: A surgical system includes a tool, a robot configured to move the tool, and a controller. The controller is programed to generate a plan for the robot to move, in a planned amount of time, the tool from a starting pose to a target pose, control the robot to provide automated movement of the tool based on the plan such that the robot moves the tool toward the target pose without requiring user assistance, and stop the automated movement if the target pose is not reached after the automated movement for the planned amount of time.

Abstract: A surgical system includes a controller and a robotic arm configured to hold a surgical tool at a distal end of the robotic arm. The controller is configured to define, based on a surgical plan, a target pose relative to a tracked position of an anatomical feature, generate a planned path for moving the surgical tool held by the robotic arm from a first pose to the target pose, output control signals configured to cause automated motion of the robotic arm based on the planned path, detect a deviation of the surgical tool from the planned path, and in response to detecting the deviation of the distal end from the planned path, update the control signals to stop the automated motion of the robotic arm.

Abstract: A method of operation of a robotically-assisted surgical system includes capturing a first pose of a surgical tool during the operation of the robotically-assisted surgical system, intraoperatively defining a target orientation for the surgical tool using the first pose of the surgical tool, and controlling a robotic device to automatically move the surgical tool to the target orientation.

Abstract: A method of operation of a robotically-assisted surgical system includes defining a virtual geometry associated with a planned resection, determining a first pose of a surgical tool, defining a target orientation for the surgical tool based on the first pose, controlling a robotic device to automatically move the surgical tool to both the virtual geometry and the target orientation

Abstract: Surgical systems and methods involve a head-mounted device (HMD) and navigation system that includes a localizer to track a pose of a surgical object. The HMD includes a display positionable in front of the eyes of a user and an input device to sense a command of the user. The HMD enables the surgical object to be observed on, or through, the display. The HMD presents a virtual model of the surgical object on the display. The HMD senses, with the input device, the command of the user to manipulate the virtual model into alignment with the surgical object. Controller(s) coupled to one or both of the navigation system and the HMD co-register the virtual model and the surgical object in response to detection of alignment between the virtual model and the surgical object.

Abstract: Disclosed are systems, methods, and techniques for registering a HMD coordinate system of a head-mounted display (HMD) and a localizer coordinate system of a surgical navigation localizer. A camera of the HMD captures at least one image of a registration device having a registration coordinate system and a plurality of registration markers. The registration markers are analyzed in the at least one image to determine a pose of the HMD coordinate system relative to the registration coordinate system. One or more position sensors comprised in the localizer detect a plurality of tracking markers comprised in the registration device to determine a pose of the registration coordinate system relative to the localizer coordinate system. The HMD coordinate system and the localizer coordinate system are registered using the registration device, wherein positions of the registration markers are known with respect to positions of the tracking markers in the registration coordinate system.
