Patent attributes
A rollable digitizer device for collecting a plurality of points on a bone that includes a wheel having multiple probes emanating circumferentially therefrom. One or more contact sensors adapted to detect if at least one of probes is in contact with the bone. The contact sensors located in the wheel, on the wheel, proximal to said one or more contact sensors, or a combination thereof. A handle connected to the wheel and adapted to permit a user to roll the probes along the bone, so each of the probes make sequential and detectable contact with the bone to facilitate the collection of multiple points on the bone. A method for collecting a multiple registration points on a bone with the rollable digitizer device includes wielding the rollable digitizer by the handle. The probes are rolled along the surface of the bone to collect the plurality of registration points.
