Abstract

A prosthetic hip installation system comprising a reamer, an impactor, a tracking element, and a remote system. The tracking element can be integrated into the reamer or impactor for providing tracking data on the position or orientation. Alternatively, the tracking element can be housed in a separate module that can be coupled to either the reamer or impactor. The tracking element will couple to a predetermined location. Points in 3D space can be registered to provide a frame of reference for the tracking element or when the tracking element is moved from tool to tool. The tracking element sends data from the reamer or impactor wirelessly. The remote system receives the tracking data and can further process the data. A display on the remote system can support placement and orientation of the tool to aid in the installation of the prosthetic component.

Claims

1. A method of surgical tracking display comprising:

moving a probe device toward a patient, where the probe is displayed as a simulated probe, where the simulated probe moves as the probe is moved by a first user, where a portion of the patient is also displayed as a displayed patient portion, where the simulated probe moves in relation to the displayed patient portion;

rotating and moving the probe to a target location and target orientation on the patient as determined by the first user;

saving the target location and target orientation of the probe;

displaying the target location as a target location mark;

displaying the target orientation as a target orientation mark;

moving a surgical device toward the patient, where the surgical device is displayed as a simulated surgical device, where the simulated surgical device moves as a second user moves the surgical device, where the simulated surgical device moves in relation to the displayed patient portion; and

rotating and moving the surgical device until the simulated surgical device is at about the target location mark and the simulated surgical device is about aligned with the target orientation mark.

2. The method according to claim 1, where the first user and the second user are the same user.

3. The method according to claim 2, where a feedback is provided to the user as the surgical device is moved to aid the user in positioning the simulated surgical device at about the target location mark and aligning the simulated surgical device with the target orientation mark.

4. The method according to claim 3, where the feedback is visual.

5. The method according to claim 3, where the feedback is haptic.

6. The method according to claim 3, where the feedback is acoustic.

7. The method according to claim 4, where the visual feedback is a colored light on the surgical device, where the color changes as the simulated surgical device is positioned at about the target location mark and aligned with the target orientation mark.

8. The method according to claim 5, where the haptic feedback is the temperature of a handle on the surgical device, where the temperature changes as the simulated surgical device is positioned at about the target location mark and aligned with the target orientation mark.

9. The method according to claim 6, where the acoustic feedback is a tone that changes as the simulated surgical device is positioned at about the target location mark and aligned with the target orientation mark.

10. The method according to claim 4, where the target location mark is displayed on a computer display, and where the target orientation mark is displayed on the computer display, where the simulated surgical device is displayed on the computer screen, where visual feedback at least includes the movement of the simulated surgical device in relation to the target location mark and the target orientation mark on the computer screen.

11. A method of surgical tracking display comprising:

moving a surgical device toward a patient, where the surgical device is displayed as a simulated surgical device, where the simulated surgical device moves as a user moves the surgical device, where the simulated surgical device moves in relation to a displayed patient portion, where a target location is displayed as a target location mark, and where a target orientation is displayed as a target orientation mark; and

rotating and moving the surgical device until the simulated surgical device is at about the target location mark and the simulated surgical device is about aligned with the target orientation mark.

12. The method according to claim 11, where a feedback is provided to the user as the surgical device is moved to aid the user in positioning the simulated surgical device at about the target location mark and aligning the simulated surgical device with the target orientation mark.

13. The method according to claim 12, where the feedback is visual.

14. The method according to claim 12, where the feedback is haptic.

15. The method according to claim 12, where the feedback is acoustic.

16. The method according to claim 13, where the visual feedback is a colored light on the surgical device, where the color changes as the simulated surgical device is positioned at about the target location mark and aligned with the target orientation mark.

17. The method according to claim 14, where the haptic feedback is the temperature of a handle on the surgical device, where the temperature changes as the simulated surgical device is positioned at about the target location mark and aligned with the target orientation mark.

18. The method according to claim 15, where the acoustic feedback is a tone that changes as the simulated surgical device is positioned at about the target location mark and aligned with the target orientation mark.

19. The method according to claim 13, where the target location mark is displayed on a computer display, and where the target orientation mark is displayed on the computer display, where the simulated surgical device is displayed on the computer screen, where visual feedback at least includes the movement of the simulated surgical device in relation to the target location mark and the target orientation mark on the computer screen.

20. The method according to claim 11, where after the step of rotating and moving the surgical device, a surgical device location is less than 3 mm from the target location and a surgical device orientation, is less than 3 degrees from the target orientation.
