Abstract: An adapter for optically coupling a conventional 2D endoscope to a stereoscopic 3D camera so as to provide stereoscopic 3D visualization of an object imaged by the conventional 2D endoscope, the adapter comprising: a body; a mechanical mount disposed on the body for mechanically mounting the adapter to a conventional 2D endoscope; means for mounting the body to a stereoscopic 3D camera; and an optical pathway disposed within the body for receiving an image from the exit pupil of the conventional 2D endoscope and projecting the received image on an appropriate portion of the stereoscopic 3D camera, wherein the optical pathway is adjustable so as to accommodate a range of different conventional 2D endoscopes.

Abstract: Apparatus for presenting a stereoscopic image to a viewer, the apparatus including an endoscope; and a stereoscopic video camera optically connected to the endoscope, wherein the stereoscopic video camera includes first and second optical channels for acquiring, respectively, first and second images of a scene from the endoscope; first and second image sensors for acquiring, respectively, the first and second images from the first and second optical channels, the first and second image sensors being positioned along an axis; and parallax adjusting means for adjusting the parallax of a stereoscopic image acquired by the first and second image sensors and presented on a display.

Abstract: A steerable stereoscopic endoscope including a shaft having a distal end, a proximal end, and an articulating region therebetween; a stereo image acquisition mechanism disposed at the distal end of the shaft for acquiring stereo images of a remote site; and a mechanism for steering the portion of the shaft distal to the articulating region.

Abstract: A stereoscopic coupler for mechanically and optically coupling an endoscope to a portion of a camera, the stereoscopic coupler including means for mechanically and optically coupling the stereoscopic coupler to an endoscope; and means for mechanically and optically coupling the stereoscopic coupler to a portion of a camera; wherein the stereoscopic coupler includes a pair of optics; a mechanical actuator for operation by a user; and means for physically moving the pair of optics as a unit in response to movement of the mechanical actuator by the user.
