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; and

an image processing module configured to display respective images from said plurality of cameras on said surgical retractor and said camera on said surgical tool for simultaneous viewing.

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

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

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

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

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