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.

1. A surgical visualization system comprising: a surgical retractor configured to hold open an incision and thereby provide a pathway for access of surgical tools to a surgical site, said retractor comprising portions configured to be disposed about an open central region centrally located between said retractor portions so as to permit access of surgical tools to the surgical site through said open central region;a plurality of cameras configured to acquire video images of the surgical site, said plurality of cameras comprising at least two cameras disposed on the retractor and configured to acquire video images within said surgical site to which the retractor provides access, said at least two cameras directed inward toward said central open region and at least one of said at least two cameras directed downward into the surgical field; andan image processing system in communication with the plurality of cameras, the image processing system comprising at least one physical processor,wherein the image processing system is configured to: receive the video images acquired by the plurality of cameras;receive input from a user indicating a selection of at least one camera from the plurality of cameras;provide output video images based on the video images acquired by the at least one selected camera; andresize, arrange, or both resize and arrange the viewable output video images from the at least one selected camera to present them on a display according to received input. 2. The surgical visualization system of claim 1, wherein the image processing system is configured to increase a size of viewable output video images from a first selected camera in relation to simultaneously viewable output video images from a second camera based at least partly on received input. 3. The surgical visualization system of claim 1, wherein the image processing system is configured to arrange viewable output video images from a first selected camera in a more central location in relation to simultaneously viewable output video from a second camera based at least partly on received input. 4. The surgical visualization system of claim 1, wherein at least one of the viewable output video images are represented by a reduced-size real-time video stream that is configured to be presented on a graphical user interface for selection by a user, wherein the graphical user interface includes a representation of a position of the retractor and the plurality of cameras. 5. The surgical visualization system of claim 1, wherein at least one of the viewable output video images is represented by a reduced-size real-time video stream that is configured to be presented on a display for selection by a user, the reduced-size real-time video stream comprising video from the respective camera. 6. The surgical visualization system of claim 1, wherein the image processing system is (a) configured to display video images that are from a camera that is not selected and that are not displayed on the display after receiving input from the user indicating a selection thereof, (b) is configured to display video images that are from the camera that is not selected and that are displayed as a reduced-size real-time video stream more prominently after receiving input from the user indicating a selection thereof, or (c) configured as set forth in both (a) and (b). 7. The surgical visualization system of claim 1, wherein the image processing system is configured to present the output video images in a tiled format. 8. The surgical visualization system of claim 7, wherein the tiled output images comprise at least three images. 9. The surgical visualization system of claim 8, wherein the image processor is configured to rotate the tiled output images around a single, common axis. 10. The surgical visualization system of claim 7, wherein the tiled output images comprise at least four images. 11. The surgical visualization system of claim 1, wherein the output video images from at least two of the plurality of cameras are discontinuous. 12. The surgical visualization system of claim 1, wherein the at least one selected camera comprises a first camera disposed on the retractor in a position opposite a second camera also disposed on the retractor. 13. The surgical visualization system of claim 12, wherein the image processing system is further configured to cause video images from said first selected camera and video images from said second camera to be rotated 180° with respect to each other. 14. The surgical visualization system of claim 1, wherein said retractor comprises a tubular retractor. 15. The surgical visualization system of claim 1, wherein said at least two cameras disposed on said retractor comprise a camera configured to be moved up and down the retractor such that the height of the camera with respect to the surgical site may be adjusted. 16. The surgical visualization system of claim 15, wherein the camera configured to be moved up and down the retractor is configured to be moved up and down the retractor via a track. 17. The surgical visualization system of claim 1, wherein said retractor has proximal and distal ends, said distal end closer to said surgical site than said proximal end, and wherein at least one of said cameras is configured to be disposed toward the distal end of the retractor. 18. The surgical visualization system of claim 1, wherein said at least two cameras disposed on said retractor have field of views with centerlines, and said at least two cameras are configured such that said centerlines converge on an area less than 500 mm2. 19. The surgical visualization system of claim 1, wherein output video images from at least two of said plurality of cameras are provided for simultaneous viewing. 20. The surgical visualization system of claim 19, wherein output video images from at least one of said at least two cameras is provided in a thumbnail. 21. The surgical visualization system of claim 1, wherein the retractor comprises a plurality of retractor blades comprising a first retractor blade and a second retractor blade, and wherein the at least two cameras comprise a first camera disposed on the first retractor blade and a second camera disposed on the second retractor blade.
