Abstract

A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the composite image generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

Claims

1-15. -15. (canceled)

16. A method comprising:

receiving from a plurality of cameras disposed on a retractor a first plurality of image data;

receiving from a camera disposed on a surgical tool a second plurality of image data;

processing the first plurality of image data to produce a first image; and

processing the second plurality of image data to produce a second image.

17. The method of claim 16, wherein producing the first image comprises tiling separate images obtained from the plurality of cameras.

18. The method of claim 16, further comprising integrating the second image with the first image.

19. The method of claim 18, wherein the integrating comprises disposing the second image as a picture-in-picture over the first image.

20. A surgical visualization kit comprising:

a plurality of cameras configured to be disposed on a retractor, said cameras configured to produce respective images;

an image processing module configured display said respective images; and

a camera configured to be disposed on a surgical tool.

21. The surgical visualization kit of claim 20, wherein the image processing module is configured to display said respective images for simultaneous viewing as a composite first image.

22. The surgical visualization kit of claim 21, wherein displaying said composite first image is produced by tiling the respective images produced by the plurality of cameras.

23. The surgical visualization kit of claim 21, wherein the image processing module is further configured to display a second image obtained from the camera configured to be disposed on the surgical tool.

24. The surgical visualization kit of claim 23, wherein the image processing module is configured to display the second image as a picture-in-picture over the first image.

25. A method comprising:

inserting a retractor into an opening in a body, the retractor comprising a plurality of cameras disposed thereon;

inserting a surgical tool at least partially into a working space of the retractor, the surgical tool comprising at least one camera disposed thereon.

26. The method of claim 25, wherein at least some of the plurality of cameras are disposed on a blade of the retractor and substantially face the working space.

27. The method of claim 25, wherein the plurality of cameras comprises at least 8 cameras.
