Abstract

An image guided surgical system and method for targeting the precise patient specific anatomical placement of surgical instruments and motion preservation implants with surgical navigation. The system and method comprising a surgical navigation system; at least one imaging system coupled to the surgical navigation system; at least one computer coupled to the surgical navigation system and the imaging system having planning software for measuring clinical parameters of anatomy of a subject to be operated on; and at least one display for displaying imaging data, planning data and tracking data.

Claims

1. A system for precise placement of a motion preservation prosthesis comprising:

a surgical navigation system;

at least one imaging system coupled to the surgical navigation system;

at least one computer coupled to the surgical navigation system and the imaging system having planning software for measuring clinical parameters of anatomy of a subject to be operated on; and

at least one display for displaying imaging data, planning data and tracking data.

2. The system of claim 1, wherein the planning software calculates patient specific dimensions for placement of the implant.

3. The system of claim 1, wherein the planning software is used to identify and mark the axial midline and sagittal midline on at least two views of images displayed on the at least one display for the anatomy being operated on.

4. The system of claim 1, wherein the planning software provides the best implant template according to the anatomy being operated on.

5. The system of claim 1, wherein the planning software and imaging provides simulation of the range of motion of the anatomy being operated on.

6. The system of claim 1, wherein the surgical navigation system provides navigation of bone markers, surgical instruments and implants.

7. The system of claim 1, further comprising a virtual template of the implant superimposed with measurements over different imaging views and providing surgical navigation of surgical instruments and implants.

8. The system of claim 1, wherein the at least one imaging system is a real-time fluoroscopic imaging system that provides updated images during surgery.

9. The system of claim 1, wherein the at least one imaging system is used to review, compare and save the implant position on the anatomy being operated on prior to closure of the surgical incision.

10. The system of claim 1, wherein the at least one display may include planning images, navigation images, and implant position images.

11. The system of claim 1, further comprising at least one microsensor attached to bones of the anatomy being operated on.

12. The system of claim 1, further comprising at least one microsensor attached to bones of the anatomy being operated on.

13. The system of claim 12, wherein the at least one microsensor is an electromagnetic field generator including at least one microcoil for generating an electromagnetic field.

14. The system of claim 12, wherein the at least one microsensor is an electromagnetic receiver for receiving an electromagnetic or magnetic field.

15. A method for targeting the precise placement of surgical instruments and implants comprising:

performing pre-operative planning and imaging;

providing surgical navigation with custom interfaces to surgical instruments and the implants to drive precise placement of the implants; and

performing an intraoperative review of the placement of the implants.

16. The method of claim 15, wherein the pre-operative planning includes planning software that calculates patient specific dimensions for placement of the implants.

17. The method of claim 16, wherein the planning software is used to identify and mark the axial midline and sagittal midline on at least two views of images displayed on the at least one display for the anatomy being operated on.

18. The method of claim 16, wherein the planning software and imaging provide simulation of the range of motion of the anatomy being operated on.

19. The method of claim 15, wherein the surgical navigation provides navigation of bone markers, surgical instruments and implants.

20. The method of claim 15, wherein the intraoperative review includes reviewing, comparing and saving the implant position on the anatomy being operated on prior to closure of the surgical incision.

21. A computer-usable medium having computer readable instructions stored thereon for execution by a processor, the computer readable instructions comprising:

a planning routine for measuring clinical parameters of anatomy of a subject to be operated on and calculating patient specific dimensions for placement of an implant;

a virtual template routine for providing a virtual template of surgical instruments and the implant; and

a simulation routine for provides simulation of the range of motion of the anatomy of the subject being operated on.

22. A computer program product for use with a computer, the computer program product comprising a computer-usable medium with computer readable instructions stored thereon for execution by a processor, the computer readable instructions stored thereon for execution by a processor performing a method comprising:

performing pre-operative imaging and planning;

performing intraoperative navigation for the precise placement of an implant; and

performing an intraoperative review to confirm the precise placement of the implant.
