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:

at least one video camera configured to acquire video images of a surgical site, said at least one video camera being a surgical microscope camera having a field of view that can be configured to include the surgical site, wherein the surgical microscope camera is configured to provide a surgical microscope view of the surgical site;

a display housing; and

a plurality, of electronic displays disposed within the display housing, each of the plurality of electronic displays comprising a plurality of pixels configured to produce a two-dimensional image, at least one of the electronic displays is configured to produce a two-dimensional image from said surgical microscope camera,

wherein the plurality of electronic displays are configured to present superimposed images in a field of view of a person'"'"'s eye, the superimposed images comprising at least one image from a first electronic display of the plurality of electronic displays and at least one image from a second electronic display of the plurality of electronic displays, the second electronic display different from the first electronic display, and

wherein said surgical microscope camera is not coupled to a direct view surgical microscope.

2. The medical apparatus of claim 1, wherein at least one of the plurality of electronic displays comprises a transmissive display panel.

3. The medical apparatus of claim 1, wherein the superimposed images comprise a video of a first portion of a surgery site that is superimposed on a video of a second portion of the surgery site, the first portion contained within the second portion.

4. The medical apparatus of claim 3, wherein the video of the first portion is magnified relative to the video of the second portion.

5. The medical apparatus of claim 1, further comprising a binocular viewing assembly comprising the display housing.

6. The medical apparatus of claim 5, wherein said binocular viewing assembly further comprises a plurality of oculars, the plurality of oculars configured to provide views of the plurality of electronic displays disposed within the display housing, the plurality of oculars comprising a left ocular and a right ocular, each ocular being tubular.

7. The medical apparatus of claim 5, further comprising:

a viewing articulating arm, the binocular viewing assembly disposed on the viewing articulating arm, the viewing articulating arm configured to adjust a position of the binocular viewing assembly; and

a second articulating arm, the surgical microscope camera disposed on the second articulating arm so that the surgical microscope camera can be positioned independently of the binocular viewing assembly.

8. The medical apparatus of claim 5, wherein the surgical microscope camera is smaller than the binocular viewing assembly.

9. The medical apparatus of claim 6, wherein said binocular viewing assembly is configured not to provide a surgical microscope view via an optical path from an ocular of said plurality of oculars through an aperture in said housing that creates a pathway to the surgical site.

10. The medical apparatus of claim 6, wherein the surgical microscope camera has an optical input for receiving light from the surgical site and the distance from the plurality of oculars to the optical input of the surgical microscope camera is not larger than the size of the binocular viewing assembly such that when in use, a surgeon can ergonomically perform surgery at a surgical site beneath the surgical microscope camera while viewing through the plurality of oculars the images displayed on the plurality of electronic displays.

11. The medical apparatus of claim 1, further comprising an external monitor.

12. The medical apparatus of claim 11, wherein the external monitor is disposed on an arm.

13. The medical apparatus of claim 1, further comprising two external monitors.

14. The medical apparatus of claim 13, wherein at least one of the two external monitors is disposed on an arm.
