Abstract: A surgical input device configured to enable manual user input to a remote computing system is described. In one example, the surgical input device comprises an interface configured to be attachable to a surgical object such as a patient bone. The surgical input device further comprises a manually operable input wheel infinitely rotatable relative to the interface. The input wheel defines an optically detectable wheel marking. In some variants, the surgical input device or surgical object may comprise one or more tracking elements and may thus function as a surgical tracker.

Abstract: A surgical navigation system including a tracker, a localizer, and a controller is provided. The tracker is coupled to a surgical object and includes tracking elements arranged in a tracker geometry. The localizer is configured to track the tracker and to detect parameters of the surgical object. The controller is in communication with the localizer and is configured to detect, with the localizer, a pose of the tracker geometry. The controller is further configured to receive a first parameter of the surgical object, create a temporary descriptor describing an appearance of the surgical object, receive a second parameter of the surgical object, and update the temporary descriptor to create an updated temporary descriptor describing the appearance of the surgical object. Finally, the controller is configured to track the surgical object based on a combination of the updated temporary descriptor and the pose of the tracker geometry.

Abstract: The invention relates to a method for navigation during medical interventions on tubular organ structures, characterized in that, before the intervention, static image data of the tubular organ structures are recorded and stored, the tubular organ structures are extracted from the image data and their course is converted into a geometric description used during the medical intervention for instrument/organ recording, and the instrument that is spatially localized by a tracking system is successively corrected in relation to the static data, by a transformation that is preferably defined by an optimization method, taking into account the geometric description and information on the previous distance covered by the instrument, or, conversely, the static data are successively corrected in relation to the instrument position, and thus the position of the instrument is associated with the anatomical structures in the static image data.
