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. A surgical visualization system comprising:

a surgical retractor configured to hold open an incision, the surgical retractor having a plurality of cameras disposed thereon;

a surgical tool having at least one camera disposed thereon;

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 binocular viewing platform 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; and

electronics in communication with said at least one display and configured to display respective images from any one of said surgical microscope camera, at least one of said plurality of cameras on said surgical retractor and said camera on said surgical tool for viewing on said at least one display so that said images are viewable through said plurality of oculars;

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

2. The surgical visualization system of claim 1, wherein the surgical tool is movable with respect to the surgical retractor.

3. The surgical visualization system of claim 1, wherein the plurality of cameras are attached to a surface of blades of the surgical retractor.

4. The surgical visualization system of claim 1, wherein the plurality of cameras are integrated within blades of the surgical retractor.

5. The surgical visualization system of claim 1, wherein the plurality of cameras comprises at least 8 cameras.

6. The surgical visualization system of claim 1, wherein the surgical tool comprises a scalpel, a rongeur, a kerrison, a laser, or a drill.

7. A surgical visualization system comprising:

a surgical retractor configured to hold open an incision, the surgical retractor having a plurality of cameras disposed thereon;

a camera configured to be associated with a surgical tool;

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 binocular viewing platform 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; and

electronics in communication with said at least one display and configured to display respective images from any one of said surgical microscope camera, at least one of said plurality of cameras on said surgical retractor and said camera associated with said surgical tool for viewing on said at least one display so that said images are viewable through said plurality of oculars;

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

8. The surgical visualization system of claim 7, wherein the plurality of cameras are attached to a surface of blades of the surgical retractor.

9. The surgical visualization system of claim 7, wherein the plurality of cameras are integrated within blades of the surgical retractor.

10. The surgical visualization system of claim 7, wherein the plurality of cameras comprises at least 8 cameras.

11. The surgical visualization system of claim 7, wherein the surgical tool comprises a scalpel, a rongeur, a kerrison, a laser, or a drill.

12. The surgical visualization system of claim 7, wherein said binocular viewing platform 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.

13. The surgical visualization system of claim 7, wherein said at least one video camera is separate from said binocular viewing platform and configured to be positioned independent of said binocular viewing platform.
