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.

1. A surgical method, comprising the steps of: creating a representation of an anatomy of a patient;associating the anatomy and a surgical device with the representation of the anatomy;manipulating the surgical device to perform a procedure on a patient by moving a portion of the surgical device in a region of the anatomy;controlling 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;monitoring a three dimensional position of the anatomy to detect movement of the anatomy during the procedure;creating a representation of a surgical tool coupled to the surgical device; andindicating an allowable angle of inclination of a shaft of the surgical tool. 2. The method of claim 1, further comprising defining a parameter relative to the representation of the anatomy. 3. The method of claim 2, further comprising controlling the surgical device to provide the at least one of haptic guidance and a limit on manipulation of the surgical device based on the parameter and the at least one of a position, an orientation, a velocity, and an acceleration of the portion of the surgical device. 4. The method of claim 1, further comprising associating a virtual object with the representation of the anatomy. 5. The method of claim 4, further comprising controlling the surgical device to provide the at least one of haptic guidance and a limit on manipulation of the surgical device based on the virtual object and the at least one of a position, an orientation, a velocity, and an acceleration of the portion of the surgical device. 6. The method of claim 4, further comprising: adjusting the virtual object in response to the detected movement. 7. The method of claim 4, wherein controlling the surgical device includes constraining the portion of the surgical device against penetrating at least a portion of the virtual object. 8. The method of claim 4, wherein at least a portion of the virtual object represents a portion of material to be removed from the anatomy. 9. The method of claim 4, wherein a shape of at least a portion of the virtual object substantially corresponds to a shape of a surface of an implant to be fitted to the anatomy. 10. The method of claim 4, further comprising superimposing a representation of the virtual object on the representation of the anatomy. 11. The method of claim 4, wherein the virtual object represents a pathway from a first position to a second position. 12. The method of claim 11, further comprising: activating the virtual object so that movement of the portion of the surgical device is constrained along the pathway; anddeactivating the virtual object when the portion of the surgical device reaches the second position. 13. The method of claim 12, further comprising deactivating the virtual object to enable the portion of the surgical device to deviate from the pathway. 14. The method of claim 1, wherein controlling the surgical device includes generating force feedback that opposes a user's manipulation of the surgical device. 15. The method of claim 14, wherein the force feedback is determined based on a proximity of the portion of the surgical device to a virtual boundary associated with the representation of the anatomy. 16. The method of claim 14, wherein a magnitude of the force feedback increases as the portion of the surgical device approaches a virtual boundary associated with the representation of the anatomy. 17. The method of claim 1, wherein the haptic guidance communicates information to a user manipulating the surgical device about a position of the portion of the surgical device relative to at least one of a virtual boundary associated with the representation of the anatomy, a parameter relative to the representation of the anatomy, and the anatomy. 18. The method of claim 1, further comprising offsetting a force feedback curve for controlling the surgical device by a desired value. 19. The method of claim 18, further comprising storing the desired value; and associating the desired value with a user. 20. The method of claim 18, wherein offsetting the force feedback curve includes increasing or decreasing a size of a haptic object. 21. The method of claim 18, wherein offsetting the force feedback curve includes increasing or decreasing a size of a representation of a surgical tool coupled to the surgical device. 22. The method of claim 1, further comprising: creating a representation of at least a portion of material to be removed from the anatomy;manipulating the surgical device to remove material from the anatomy; andcreating a representation of the material removed by the surgical device.
