Abstract: A system for confirming registration of a bone involved in a joint replacement procedure is provided. The system includes a three-dimensional (3-D) bone model of the bone registered to a bone location, a visible light camera, and a display. The visible light camera captures images of the bone in the camera’s field-of-view (FOV). The display is configured to display the captured images of the FOV and an image of the 3-D bone model, where the displayed location of the image of the 3-D bone model corresponds to the location of the 3-D bone model registered to the bone location. The registration may be confirmed if the displayed location of the image of the bone as captured by the visible light camera corresponds to the displayed location of the 3-D bone model.

Abstract: Systems and methods are provided to aid in planning at least a portion of a total knee arthroplasty procedure. The system and method automatically aligns the implant components and the bones according to a desired clinical alignment goal with minimum user input. The system and method further allows the user to adjust the position and orientation of the femur, tibia, or implant in a clinical direction regardless of a pre-adjusted position and orientation of the femur, tibia, or implant. The graphical user interface is provided that includes a three-dimensional (3-D) view window, a view options window, a patient information window, an implant family window, a workflow-specific tasks window, and a limb and knee alignment measures window.

Abstract: A process for confirming registration of bones involved in a joint replacement procedure is provided that includes a three dimensional (3-D) models of the bones being generated. The bones are tracked with a tracking device attached to each of the bones to allow 6-degrees of freedom (DOF) tracking during the joint replacement procedure. The 3-D models to the bones are registered and the bones having the tracking device are moved. A corresponding motion in the 3-D models with the moving of the bones is then observed. The registration of the 3-D models to the bone when the observations of the 3-D models move in correspondence with the actual bones is then confirmed or an alarm when an algorithm detects the 3-D bone models move unexpectedly during the movement of the bones. A system for confirming registration of bones involved in the joint replacement procedure is also provided.

Abstract: A method for verifying the calibration of a digitizer during a computer-assisted medical procedure is provided utilizing a tracked digitizer and a secondary tracking array (e.g., a bone tracking array). A medical system for performing the computerized method for verifying the calibration of a digitizer during a computer-assisted medical procedure is provided. A method for verifying the calibration of a tracking array relative to a feature with the system includes a first calibration definition and a second calibration definition transmitted to the tracking system. A first feature and a second feature together are assembled. The calibration is verified by computing the deviations between the tracked position of the first feature and the tracked position of the second feature using: a recorded position and orientation of the first and second tracking array, and the uploaded first calibration definition and the uploaded second calibration definition.

Abstract: Systems and methods for creating planar cuts on a bone are provided utilizing one or more cutting guides assembled to a plurality of bone pins, where the bone pins are inserted on the bone coincident with one or more virtual pin planes defined relative to one or more of the planar cuts. Alignment guides are also disclosed herein that aid in the creation of pilot holes for receiving a cutting block in a desired position and orientation (POSE). An articulating surgical device actively positions the bone pins coincident with the virtual plane to ensure the cutting guides, when assembled to the pins, aligns one or more guide slots in the desired POSE to create the planar cuts.

Abstract: A protective drape for a robotic arm is provided. The protective drape may be used with robotic arm that are required to operate in varied environments that illustratively include industrial applications, a sterile surgical suite for patient care, and a clean room for manufacturing sensitive electronic components. In each of these applications, there is a need to prevent contaminants from infiltrating from the environment to the robot and affecting operation of the robot itself or the robotic system, as well to prevent contaminants from the robot from infecting a patient or contaminating an assembly or process product.

Abstract: A system and method are provided to optically track a subject's anatomy without the need for the use of invasive pins and screws currently used to support and attach six-degree-of-freedom fiducial arrays directly to the bone. The system and method is especially advantageous for surgical procedures involving brittle or osteoporotic bone or any other procedure where the preservation of surrounding healthy bone is desirable. The system and method are advantageous for computer-assisted total knee arthroplasty, revision knee arthroplasty, and other medical procedures where the position and orientation (POSE) of bone surface cuts planes are critical for successful placement and correct alignments of joint implants. Often, these procedures require a form of external support to reduce the motion of the bones relative to the computer-assisted device.
