    摘要: A surgical microscope comprising a microscope body, lens means attached to the microscope body for magnifying an object image, an eyepiece attached to the microscope body for viewing the magnified object image, and coupling means attached to the microscope body for retaining a supplementary lens in optical alignment with the lens means, the coupling means being configured for introducing the supplementary lens through a percutaneous penetration into a body cavity, wherein the eyepiece and the lens means are configured to facilitate stereoscopic viewing. In a variation of the surgical microscope, a plurality of binocular eyepieces are attached to the microscope body to allow multiple persons to contemporaneously view the magnified object image.

    摘要: The invention provides a percutaneous visualization system for direct, stereoscopic visualization of a body cavity during minimally-invasive surgical procedures. The visualization system includes a cannula having a distal end, a proximal end, and a passage extending therebetween. The passage is configured to allow stereoscopic vision therethrough, and is preferably tapered from the proximal end to the distal end. A sleeve is positionable in the passage of the cannula, the sleeve having an optical passage also configured to allow stereoscopic vision, preferably by tapering. A lens may be disposed in the optical passage of the sleeve tier wide-angle viewing. Magnification means may be positioned in optical alignment with the optical passage to provide a magnified image of a surgical site.
