Abstract

A medical apparatus is configured to provide visualization of a surgical site. The medical apparatus includes an electronic display disposed within a display housing. 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 images from the electronic display. The medical apparatus can include proximal cameras mounted on a frame, the cameras configured to provide a view of a surgical site from outside the surgical site. The display housing can have a height that is larger than its depth.

4. The medical apparatus of claim 1, wherein a distance from the eye portal to the electronic display along a direction parallel to the optical path at the eye portal is less than or equal to the distance from the eye portal to the electronic display along a direction orthogonal to the optical path at the eye portal.

5. The medical apparatus of claim 4, wherein a distance from the eye portal to the electronic display along a direction parallel to the optical path at the eye portal is less than or equal to 70% of the distance from the eye portal to the electronic display along a direction orthogonal to the optical path at the eye portal.

6. The medical apparatus of claim 1, wherein the electronic display is positioned above the eye portal when the eye portal is positioned such that the portion of the optical path of the eye portal is horizontal.

7. The medical apparatus of claim 1, wherein at least 50% and less than or equal to 95% of the plurality of optical elements of the display optical system are positioned above the eye portal when the eye portal is positioned such that the portion of the optical path of the eye portal is horizontal.

18. The medical apparatus of claim 1, wherein at least 50% of the total length of the optical path is above the eye portal when the display housing is oriented such that the portion of the optical path through the eye portal is horizontal.

19. The medical apparatus of claim 1, wherein at least 70% of the total length of the optical path is above the eye portal when the display housing is oriented such that the portion of the optical path through the eye portal is horizontal.

20. The medical apparatus of claim 1, wherein at least 90% of the total length of the optical path is above the eye portal when the display housing is oriented such that the portion of the optical path through the eye portal is horizontal.

21. The medical apparatus of claim 1, wherein the eye portal comprises a right eye portal.

22. The medical apparatus of claim 21, further comprising a left eye portal.

23. The medical apparatus of claim 1, wherein the eye portal comprises an ocular.

26. The medical apparatus of claim 1, wherein the camera is not coupled to a direct view surgical microscope.
