Method and apparatus for aligning and securing an implant relative to a patient

摘要

A surgical apparatus includes an orientation sensor that detects an actual orientation of a surgical tool. The apparatus also includes a tactile orientation feedback device that selectively provides a tactile orientation feedback signal. Moreover, the apparatus includes a controller that causes the tactile orientation feedback device to provide the tactile orientation feedback signal when the actual orientation of the surgical tool detected by the orientation sensor is substantially equal to a predetermined target orientation of the surgical tool.

1. A surgical apparatus comprising:
an impactor tool having an elongated shaft defining a load axis, a head at a first end, and a second end configured to removably couple to a prosthetic; an orientation sensor configured to detect an actual orientation of the impactor tool; an orientation feedback device configured to selectively provide an orientation feedback signal; a controller configured to cause the orientation feedback device to provide the orientation feedback signal when the actual orientation of the impactor tool detected by the orientation sensor is substantially equal to a predetermined target orientation of the impactor tool associated with a desired implanted orientation of the prosthetic relative to the patient's anatomy: an impact sensor configured to detect an actual effect of impacting the impactor tool; and an impact feedback device configured to selectively provide an impact feedback signal; wherein the controller is configured to cause the impact feedback device to provide the impact feedback signal when the actual effect of impacting the impactor tool detected by the impact sensor substantially meets or exceeds a target effect.
