Abstract

A medical apparatus is described for providing visualization of a surgical site. The medical apparatus includes an electronic display disposed within a display housing, the electronic display configured to produce a two-dimensional image. The medical apparatus includes a display optical system disposed within the display housing, the display optical system comprising a plurality of lens elements disposed along an optical path. The display optical system is configured to receive the two-dimensional image from the electronic display, produce a beam with a cross-section that remains substantially constant along the optical path, and produce a collimated beam exiting the opening in the display housing. The medical apparatus can also include an auxiliary video camera configured to provide an oblique view of a patient on the electronic display without requiring a surgeon to adjust their viewing angle through oculars viewing the electronic display.

Claims

1. A medical apparatus comprising:

a first display portion configured to display a first image;

a second display portion configured to display a second image;

electronics configured to receive one or more signals corresponding to images from a plurality of sources and to drive said first and second display portions to produce said first and second images based at least in part on said images from said plurality of sources; and

a first beam combiner configured to receive said first and second images from said first and second display portions and to combine said first and second images for viewing.

2. The medical apparatus of claim 1, wherein said first and second display portions comprise first and second displays.

3. The medical apparatus of claim 1, further comprising a housing and a first ocular for viewing the combined first and second images within said housing.

4. The medical apparatus of claim 3, further comprising a second ocular for viewing an additional image within said housing.

5. The medical apparatus of claim 1, further comprising imaging optics disposed to collect light from both said first and second display portions.

6. The medical apparatus of claim 5, wherein said imaging optics are configured to form images at infinity.

7. The medical apparatus of claim 1, wherein said plurality of sources comprises at least one camera providing a surgical microscope view.

8. The medical apparatus of claim 7, further comprising said at least one camera providing said surgical microscope view.

9. The medical apparatus of claim 1, wherein said plurality of sources comprises at least one camera disposed on an endoscope.

10. The medical apparatus of claim 9, further comprising said at least one camera disposed on said endoscope.

11. The medical apparatus of claim 1, wherein said plurality of sources comprises at least one source providing data, a computed tomography scan, a computer aided tomography scan, magnetic resonance imaging, an x-ray, or ultrasound imaging.

12. The medical apparatus of claim 11, further comprising said at least one source providing said data, computed tomography scan, computer aided tomography scan, magnetic resonance imaging, x-ray, or ultrasound imaging.

13. The medical apparatus of claim 1, wherein said first image comprises a fluorescence image and said second image comprises a non-fluorescence image.

14. The medical apparatus of claim 1, further comprising:

a third display portion configured to display a third image;

a fourth display portion configured to display a fourth image; and

a second beam combiner configured to receive said third and fourth images from said third and fourth display portions and to combine said third and fourth images for viewing.

15. The medical apparatus of claim 14, wherein said third and fourth display portions comprise third and fourth displays.

16. The medical apparatus of claim 14, further comprising a housing, a first ocular for viewing the combined first and second images within said housing, and a second ocular for viewing the combined third and fourth images within said housing.

17. The medical apparatus of claim 14, further comprising additional electronics configured to receive one or more signals corresponding to images from another plurality of sources and to drive said third and fourth display portions to produce said third and fourth images based at least in part on said images from said another plurality of sources.

18. The medical apparatus of claim 14, further comprising imaging optics disposed to collect light from both said third and fourth display portions.

19. The medical apparatus of claim 18, wherein said imaging optics are configured to form images at infinity.

20. The medical apparatus of claim 17, wherein said another plurality of sources comprises at least one camera providing a surgical microscope view.

21. The medical apparatus of claim 20, further comprising said at least one camera providing said surgical microscope view.

22. The medical apparatus of claim 17, wherein said another plurality of sources comprises at least one camera disposed on an endoscope.

23. The medical apparatus of claim 22, further comprising said at least one camera disposed on said endoscope.

24. The medical apparatus of claim 17, wherein said another plurality of sources comprises at least one source providing data, a computed tomography scan, a computer aided tomography scan, magnetic resonance imaging, an x-ray, or ultrasound imaging.

25. The medical apparatus of claim 24, further comprising said at least one source providing said data, computed tomography scan, computer aided tomography scan, magnetic resonance imaging, x-ray, or ultrasound imaging.

26. The medical apparatus of claim 14, wherein said third image comprises a fluorescence image and said fourth image comprises a non-fluorescence image.

27. The medical apparatus of claim 1, wherein said medical apparatus provides 3D viewing of a surgical field.

28. The medical apparatus of claim 1, wherein the combined first and second images for viewing comprises a composite image of said first and second images, wherein said first beam combiner is configured to produce said first image as a background image of said composite image, and to produce said second image as a picture-in-picture (PIP) of said composite image.

29. The medical apparatus of claim 14, wherein the combined third and fourth images for viewing comprises a composite image of said third and fourth images, wherein said second beam combiner is configured to produce said third image as a background image of said composite image, and to produce said fourth image as a picture-in-picture (PIP) of said composite image.
