Abstract
The invention relates to a surgical system and, more particularly, to a surgical system and method for verifying calibration of a surgical device. The surgical system or method can be configured to perform the steps of: identifying an interface on an anatomy of a patient, determining a position of a checkpoint of the interface in a coordinate frame of reference, contacting the interface with a portion of a surgical tool of the surgical device, determining a position of the portion of the surgical tool in the coordinate frame of reference, and determining whether the position of the portion of the surgical tool has an expected correspondence to the position of the checkpoint. The interface may comprise a painted portion of a bone of the patient, a divot made in the bone, or a mechanical interface that includes a portion configured to be affixed to the bone and an interface portion that is configured to be contacted by the portion of the surgical tool.
