Patent ID: 8167823

Claim:
A surgical apparatus comprising: an orientation sensor that detects an actual orientation of a surgical tool; a plurality of orientation feedback devices, each of the plurality of orientation feedback devices providing an orientation feedback signal, the plurality of orientation feedback devices including at least two of a visual feedback device, an audible feedback device, and a tactile feedback device; a controller that causes the plurality of orientation feedback devices to each provide the respective 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; and an impact sensor that detects an actual acoustic effect of impacting the surgical tool, an impact feedback device that selectively provides an impact feedback signal, and wherein the controller causes the impact feedback device to provide the impact feedback signal when the actual acoustic effect of impacting the surgical tool detected by the impact sensor substantially matches a predetermined target acoustic effect of impacting the surgical tool.
