A system for verifying a tool for use in a surgical procedure includes a mechanical interface configured to be affixed to a portion of a patient's anatomy, wherein the mechanical interface comprises at least a first portion having a first diameter and a second portion having a second diameter. The system further includes a probe configured to be inserted into the mechanical interface to establish a checkpoint location, and a computing system configured to determine a location of a portion of the probe when the probe is inserted a maximum distance into the mechanical interface, wherein the location of the portion of the probe establishes the checkpoint location. The computing system is further configured to verify a surgical tool by comparing the checkpoint location to a location of a portion of the surgical tool when the surgical tool is inserted a maximum distance into the mechanical interface.

System and method for verifying calibration of a surgical device

A method for joint replacement is provided. A representation of a first bone is created, and a representation of a second bone is created. Bone preparation for implanting a first implant on the first bone is planned. The first bone to receive the first implant is prepared by manipulating a surgical tool to sculpt the first bone. Bone preparation for implanting a second implant on the second bone after preparing the first bone is planned. The second bone to receive the second implant is prepared by manipulating the surgical tool to sculpt the second bone.

Haptic guidance system and method

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.

A surgical apparatus includes a surgical device, configured to be manipulated by a user to perform a procedure on a patient, and a computer system. The computer system is programmed to create a representation of an anatomy of a patient; to associate the anatomy and a surgical device with the representation of the anatomy; to manipulate the surgical device to perform a procedure on a patient by moving a portion of the surgical device in a region of the anatomy; to control the surgical device to provide at least one of haptic guidance and a limit on manipulation of the surgical device, based on a relationship between the representation of the anatomy and at least one of a position, an orientation, a velocity, and an acceleration of a portion of the surgical device; and to adjust the representation of the anatomy in response to movement of the anatomy during the procedure.

A surgical planning method is provided. A representation of a bone of a joint is created. The joint is moved to a first position. A first point corresponding to a first location in the joint is identified when the joint is in the first position. The joint is moved to a second position. A second point corresponding to a second location in the joint is identified, when the joint is in the second position. Bone preparation for implanting an implant on the bone is planned based at least in part on the first and second points.
