Systems and methods for surgical navigation

A head-mounted device (HMD) comprising:

• a display positionable in front of the eyes of a user of the HMD to enable the user to observe a surgical object on, or through, the display;
• an input device configured to sense a command of the user;
• and
• an HMD controller configured to:
• present a virtual model of the surgical object on the display;
• sense, with the input device, the command of the user to manipulate the virtual model into alignment with the surgical object;
• detect alignment between the virtual model and the surgical object;
• and
• co-register the virtual model and the surgical object in response to detection of alignment between the virtual model and the surgical object.

A method of operating a surgical system, the surgical system including a navigation system including a localizer to track a pose of a surgical object, a head-mounted device (HMD) including a display positionable in front of the eyes of a user of the HMD to enable the user to observe the surgical object on, or through, the display, an input device of the HMD to sense a command of the user, and one or more controllers coupled to one or both of the navigation system and the HMD, the method comprising the one or more controllers performing the following:

• presenting a virtual model of the surgical object on the display of the HMD;
• sensing, with the input device, the command of the user for manipulating the virtual model into alignment with the surgical object;
• and
• detecting alignment between the virtual model and the surgical object;
• and
• co-registering the virtual model and the surgical object in response to detection of alignment between the virtual model and the surgical object.
