Abstract

A modular portal for use with a computer-aided surgical navigation system. The modular portal is configured to receive a wide number of surgical items in either rotating or non-rotating fashions. A surgical reference associated with a base of the modular portal may be repositioned with respect to the base to facilitate a clear line of sight between a sensor of the computer-aided surgical navigation system and the surgical reference.

Claims

1. A modular portal for use with a computer-aided surgical navigation system, the system comprising:

a sensor, which senses the position and orientation of a surgical reference associated with the modular portal;

computer functionality, which receives information from the sensor about position and orientation of the surgical reference and generates information corresponding to position and orientation of a surgical item; and

rendering functionality, which renders at least the position and orientation of the surgical item in correspondence with the position and orientation of the surgical reference as sensed by the sensor;

the modular portal comprising;

(a) a base comprising an aperture extending through the base;

(b) a surgical reference associated with the base;

(c) a first surgical item securable to the base; and

(d) a second surgical item securable to the base

wherein at least one of the first surgical item and second surgical item are secured to the base and wherein the surgical item secured to the base extends through the aperture of the base.

2. The modular portal of claim 1, wherein the first surgical item is able to be rotated with respect to the base when the first surgical item is secured to the base.

3. The modular portal of claim 1, wherein the first surgical item is not able to be rotated with respect to the base when the first surgical item is secured to the base.

4. The modular portal of claim 1, wherein the first surgical item defines an aperture.

5. The modular portal of claim 4, wherein the first surgical item comprises a sleeve.

6. The modular portal of claim 1, further comprising suction functionality.

7. The modular portal of claim 6, further comprising a handle extending from the base;

and wherein the handle further comprises a suction tube.

8. The modular portal of claim 1, further comprising at least one interface button.

9. The modular portal of claim 8, further comprising a handle extending from the base;

and wherein the at least one interface button is located on the handle.

10. The modular portal of claim 1, wherein the surgical reference is able to be repositioned with respect to the base.

11. The modular portal of claim 10, further comprising a support member;

wherein the support member is secured to the base;

wherein the support member supports the surgical reference; and

wherein the support member is able to be repositioned with respect to the base.

12. The modular portal of claim 11, wherein the support member is able to be repositioned with respect to the base in one of a plurality of discrete orientations.

13. The modular portal of claim 12, wherein a plurality of notches in the support member determine the plurality of discrete orientations.

14. A method for performing a surgical procedure using a modular portal and a computer-aided surgical navigation system, the system comprising:

a sensor, which senses the position and orientation of a surgical reference associated with the modular portal;

computer functionality, which receives information from the sensor about position and orientation of the surgical reference and generates information corresponding to position and orientation of a surgical item; and

rendering functionality, which renders at least the position and orientation of the surgical item in correspondence with the position and orientation of the surgical reference as sensed by the sensor;

the method comprising;

(a) assembling a modular portal, wherein the modular portal comprises;

(i) a base comprising an aperture extending through the base;

(ii) a surgical reference associated with the base;

(iii) a first surgical item securable to the base; and

(iv) a second surgical item securable to the base

wherein assembling the modular portal comprises securing at least one of the first surgical item and second surgical item to the base and wherein the surgical item secured to the base extends through the aperture of the base;

(b) using the first surgical item to perform a first surgical procedure;

(c) securing a second surgical item to the base;

(d) using the second surgical item to perform a second surgical procedure.

15. The method for performing a surgical procedure of claim 14, further comprising using the modular portal to provide suction.

16. The method for performing a surgical procedure of claim 14, further comprising repositioning the surgical reference with respect to the base.

17. The method for performing a surgical procedure of claim 16, wherein repositioning the surgical reference with respect to the base comprises rotating a support member with respect to the base.

18. The method for performing a surgical procedure of claim 14, further comprising using an interface button on the modular portal to communicate with the computer-aided surgical navigation system.

19. The method for performing a surgical procedure of claim 14, further comprising installing an implant.

20. The method for performing a surgical procedure of claim 19, wherein installing an implant is installing a intramedullary nail, installing a hip implant, installing a knee implant or installing a shoulder implant.
