Binocular viewing assembly for a surgical visualization system
First Claim
1. A medical apparatus comprising:
- a retractor configured to hold open an incision to 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, at least one of the plurality of cameras comprising a first camera disposed on the retractor and configured to acquire video images within the opening provided by the retractor, wherein said first camera of the plurality of cameras is configured to provide first video images, the first video images being stereo video images;
an auxiliary optical assembly comprising a left-eye camera and a right-eye camera included in said plurality of cameras, said left-eye camera and said right-eye camera configured to provide a stereoscopic surgical microscope view of the surgical site and to provide second stereo video images corresponding to said stereoscopic surgical microscope view, said left-eye camera and said right-eye camera configured to be disposed left and right with respect to each other and with respect to the surgical sight to provide left and right views thereof;
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, said plurality of oculars including a left ocular and a right ocular similarly disposed left and right with respect to said surgical site so as to coincide with said left-eye camera and said right-eye camera, said at least one display configured to receive and to display output video images based on the first stereo video images and the second stereo video images;
a viewing arm, the binocular viewing assembly disposed on the viewing arm, the viewing arm configured to support the binocular viewing assembly; and
a support, the viewing arm attached to the support;
wherein said left-eye camera and said right-eye camera have optical inputs for receiving light from said surgical site and the distance from said left and right oculars to said optical input of said left-eye camera and said optical input of said right-eye camera is not larger than the size of said binocular viewing assembly such that when in use, a surgeon can ergonomically perform surgery at a surgical site beneath the auxiliary optical assembly while viewing through the plurality of oculars the output video images of the surgical site displayed on said at least one display, andwherein said left-eye camera and said right-eye camera are not coupled to a direct view surgical microscope.

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.
