1. 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.

Abstract
A surgical apparatus includes an orientation sensor that detects an actual orientation of a surgical tool. The apparatus also includes an orientation feedback device that selectively provides an orientation feedback signal. Moreover, the apparatus includes a controller that causes the orientation feedback device to provide the 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.

21. A method of implanting a prosthetic implant in a patient with an impactor tool comprising:
-
determining a target orientation of the impactor tool necessary for moving the prosthetic implant to a target location; automatically detecting an actual orientation of the impactor tool; automatically providing an orientation feedback signal when the actual orientation of the impactor tool is substantially equal to the target orientation of the impactor tool; impacting the impactor tool while the actual orientation of the impactor tool is substantially equal to the target orientation of the impactor tool to move the prosthetic implant substantially toward the target location; automatically detecting an actual acoustic impact effect of impacting the impactor tool; and automatically providing an impact feedback signal when the actual acoustic impact effect substantially matches a predetermined target acoustic impact effect. - View Dependent Claims (22)

23. An impactor assembly for implanting an acetabular cup of a prosthetic hip assembly in a patient, the impactor assembly comprising:
-
an impactor tool having an elongated shaft defining a load axis, a head at a first end, and a coupling mechanism at a second end for removably coupling to the acetabular cup, the impactor tool for transferring a load from impacting the impactor tool along the load axis to the acetabular cup; and an implanting apparatus that is operatively coupled to the impactor tool, the implanting apparatus comprising; an orientation sensor that detects an actual inclination angle of the load axis relative to a median plane of the patient and that detects an actual anteversion angle of the load axis relative to a coronal plane of the patient; 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 a visual feedback device, an audible feedback device, and a tactile feedback device; an impact sensor that detects an actual effect of impacting the impactor tool, the actual effect of impacting the impactor tool including an actual acoustic effect of impacting the impactor tool; an impact feedback device that selectively provides an impact feedback signal; and a controller that causes the plurality of orientation feedback devices to each provide the respective orientation feedback signal when the actual inclination angle is substantially equal to a predetermined target inclination angle and the actual anteversion angle is substantially equal to a predetermined target anteversion angle, the controller also causing the impact feedback device to provide the impact feedback signal when the actual acoustic effect of impacting the impactor tool detected by the impact sensor substantially matches a predetermined target acoustic effect of impacting the impactor tool. - View Dependent Claims (24)
