Abstract

A surgical device includes one or more cameras integrated therein. The view of each of the one or more cameras can be integrated together and provided to a surgeon display and/or an assistant display. 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 images generated by the one or more 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 at least partially transparent. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

Claims

1. A medical apparatus comprising:

a surgical retractor configured to hold open an incision and to provide access to a surgical site;

a camera disposed on the surgical retractor, the camera configured to acquire video images of the surgical site within the opening provided by the retractor;

a surgeon viewing assembly comprising a surgeon display housing, at least one surgeon display within the surgeon display housing, and surgeon binoculars configured to provide a view of the at least one surgeon display, the at least one surgeon display being configured to provide images from the camera; and

an assistant viewing assembly comprising an assistant display housing, at least one assistant display within the assistant display housing, and assistant binoculars configured to provide a view of the at least one assistant display, the at least one assistant display being configured to provide images from the camera.

2. The medical apparatus of claim 1, further comprising an image processing system in communication with the camera, the at least one surgeon display, and the at least one assistant display, the image processing system comprising at least one physical processor, wherein the image processing system is configured to:

receive video images acquired by the camera,

provide to the at least one surgeon display surgeon output video images based on the received video images, and

provide to the at least one assistant display assistant output video images based on the received video images.

3. The medical apparatus of claim 2, wherein the image processing system is further configured to orient the assistant output video images relative to the surgeon output video images according to a relative orientation of the surgeon viewing assembly and the assistant viewing assembly.

4. The medical apparatus of claim 3, wherein the assistant output video images are rotated relative to the surgeon output images, an angle of rotation being between 30 degrees and 180 degrees.

5. The medical apparatus of claim 4, wherein the angle of rotation is about 90 degrees.

6. The medical apparatus of claim 4, wherein the angle of rotation is about 180 degrees.

7. The medical apparatus of claim 1, further comprising a first support, the surgeon viewing assembly attached to the first support such that a position and/or orientation of the surgeon viewing assembly is adjustable.

8. The medical apparatus of claim 7, wherein the assistant viewing assembly is attached to the first support, the assistant viewing assembly independently adjustable from the surgeon viewing assembly.

9. The medical apparatus of claim 7, further comprising a second support separate from the first support, the assistant viewing assembly attached to the second support such that a position and/or orientation of the assistant viewing assembly is adjustable.

10. The medical apparatus of claim 1, wherein said camera comprises a stereo camera dedicated to providing video images of the surgical site to be displayed on the at least one assistant display.

11. The medical apparatus of claim 1, wherein the image processing system is configured to provide 3-D surgeon output video images for viewing on the at least one surgeon display through the surgeon binoculars.

12. The medical apparatus of claim 1, further comprising a surgical microscope camera configured to provide a surgical microscope view of the surgical site, wherein the at least one surgeon display and the at least one assistant display are configured to provide images from the surgical microscope camera.

13. The medical apparatus of claim 12, further comprising an image processing system configured to rotate images of the field of view from the surgical microscope camera and provide the rotated images to the at least one assistant display.

14. The medical apparatus of claim 1, wherein the surgeon viewing assembly does not provide a view of the surgical site via an optical pathway that passes through the surgeon display housing from the surgeon binoculars to the surgical site.

15. The medical apparatus of claim 14, wherein the assistant viewing assembly does not provide a view of the surgical site via an optical pathway that passes through the assistant display housing from the assistant binoculars to the surgical site.

16. The medical apparatus of claim 1, further comprising a surgical tool having a camera disposed thereon, wherein the at least one surgeon display and the at least one assistant display are configured to provide images from the camera disposed on the surgical tool.

17. A medical apparatus comprising:

a surgical retractor configured to hold open an incision and to provide access to a surgical site;

a camera disposed on the surgical retractor, the camera configured to acquire video images of the surgical site within the opening provided by the retractor;

a binocular viewing assembly comprising a housing and a plurality of oculars, the plurality of oculars configured to provide views of at least one display disposed in the housing;

a viewing arm, the binocular viewing assembly disposed on the viewing arm, the viewing arm configured to support the binocular viewing assembly over the retractor;

a support, the viewing arm attached to the support; and

an image processing system in communication with the camera and the at least one display, the image processing system comprising at least one physical processor,

wherein the image processing system is configured to;

receive video images acquired by the camera,

provide output video images based on the received video images, and

present the output video images on the at least one display so that the output video images are viewable through the plurality of oculars,

wherein the binocular viewing assembly does not provide a view of the surgical site through the oculars via an optical pathway that passes through the housing from the oculars to the surgical site.

18. The medical apparatus of claim 17, wherein the image processing system is further configured to provide 3-D viewing of camera images through the binoculars.

19. The medical apparatus of claim 17, further comprising an assistant viewing assembly comprising an assistant display housing and assistant binoculars, the assistant binoculars configured to provide views of at least one assistant display disposed in the assistant display housing.

20. The medical apparatus of claim 19, wherein the apparatus is configured such that to view the at least one assistant display through the assistant binoculars, a user is in close proximity to the surgical site.

21. The medical apparatus of claim 19, wherein the apparatus is configured such that to view the at least one assistant display through the assistant binoculars, a user is within 2 feet of the surgical site.

22. The medical apparatus of claim 17, further comprising a surgical tool having a camera disposed thereon, wherein the at least one display is configured to provide images from the camera disposed on the surgical tool.

23. The medical apparatus of claim 17, wherein the apparatus is configured such that to view the at least one display through the plurality of oculars, a user is in close proximity to the surgical site.

24. The medical apparatus of claim 17, wherein the apparatus is configured such that to view the at least one display through the plurality of oculars, a user is within 2 feet of the surgical site.
