Abstract: A handpiece arrangement for a tool having a retaining member configured to receive a portion of the tool in a secure position, a guard configured to cover a portion of the tool, at least one mounting member configured to receive a portion of a tracking system and an actuator mounted to the handpiece. The actuator may be configured to control the exposure of the tool. A navigated surgery kit is also provided including a tracking system, a tool in communication with the tracking system, a platform in communication with the tracking system and the tool. The platform may have a processor, a computer readable storage medium having computer readable program code configured to selectively control shaping of an object with the tool via at least one hidden object associated with a predetermined navigated surgical operation.

Abstract: A reconfigurable tracking arrangement for an object includes a repositionable mounting arrangement that may be configured to releasably connect to an object for selectively positioning the same. The mounting arrangement may further include a first piece attached to the object and a second piece that can be repositioned relative to the first piece. In addition, the mounting arrangement may be configured to be secured in at least two stable pre-configured positions about the object.

Abstract: An augmented reality device to combine a real world view with an object image. An optical combiner combines the object image with a real world view of the object and conveys the combined image to a user. A tracking system tracks one or more objects. At least a part of the tracking system is at a fixed location with respect to the display. An eyepiece is used to view the combined object and real world images, and fixes the user location with respect to the display and optical combiner location.
