Abstract

Systems and methods for arranging objects in an operating room in preparation for a surgical procedure. The objects are arranged based on surgical procedure information provided to a guidance station. The surgical procedure information dictates the desired placement of the objects. Placement of the objects is then guided according to their desired placement using one or more tracking elements.

First claim

What is claimed is:

1. A method for arranging a plurality of objects in an operating room using a guidance station having a sensing device and a display, the plurality of objects including first and second anatomy tracking devices for tracking a patient, said method comprising:
receiving surgical procedure information at the guidance station;
determining a desired placement of the first and second anatomy tracking devices with respect to the patient based on the surgical procedure information wherein each of the first and second anatomy tracking devices is capable of communication with the guidance station;
detecting line-of-sight errors between the first and second anatomy tracking devices and the sensing device of the guidance station; and
guiding placement of the first and second anatomy tracking devices with respect to the patient according to the desired placements of the first and second anatomy tracking devices and based on the detected line-of-sight errors.

2. A method as set forth in claim 1 including displaying representations of the desired placements of the first and second anatomy tracking devices with respect to the patient to guide placement of the first and second anatomy tracking devices with respect to the patient.

3. A method as set forth in claim 2 including displaying representations of actual placements of the first and second anatomy tracking devices with respect to the desired placements of the first and second anatomy tracking devices.

4. A method as set forth in claim 2 wherein guiding placement of the first and second anatomy tracking devices includes guiding placement of the first and second anatomy tracking devices to avoid obstructions to line-of-sight between the first and second anatomy tracking devices and the sensing device of the guidance station.

5. A method as set forth in claim 2 wherein guiding placement of the first and second anatomy tracking devices includes:
guiding placement of the first anatomy tracking device with respect to a first bone of the patient; and
guiding placement of the second anatomy tracking device with respect to a second bone of the patient.

6. A method as set forth in claim 5 wherein displaying representations of the desired placements of the first and second anatomy tracking devices with respect to the patient includes displaying representations of the desired placements of the first and second anatomy tracking devices with respect to the first and second bones.

7. A method as set forth in claim 5 including checking for an error in actual placements of the first and second anatomy tracking devices with respect to the first and second bones relative to the desired placements of the first and second anatomy tracking devices and determining whether the error is within a predefined tolerance.

8. A method as set forth in claim 7 including registering the first and second anatomy tracking devices to images of the first bone and the second bone.

9. A method as set forth in claim 1 including:
determining a desired placement of a robotic machining station in the operating room based on the surgical procedure information, the robotic machining station being capable of communication with the guidance station; and
guiding placement of the robotic machining station in the operating room according to the desired placement of the robotic machining station and prior to surgery on the patient, wherein the guidance station displays a representation of the desired placement of the robotic machining station.

10. A method as set forth in claim 1 wherein detecting line-of-sight errors includes modeling the first and second anatomy tracking devices and the sensing device for anticipated positions of the first and second anatomy tracking devices.

11. A method as set forth in claim 1 wherein receiving the surgical procedure information at the guidance station includes receiving an identification of a bone to be treated and an identification of a desired implant to be attached to the bone.

12. A method as set forth in claim 1 including displaying instructions to a user to guide placement of the first and second anatomy tracking devices with respect to the patient.

13. A method as set forth in claim 1 including displaying a desired operating room layout to guide placement of other objects in the operating room.

14. A method as set forth in claim 1 including displaying instructions on placement of the sensing device of the guidance station to guide placement of the sensing device in the operating room.

15. A method as set forth in claim 1 including displaying instructions on placement of the patient to guide placement of the patient in the operating room.
