Abstract
An endoscopic photographic system includes the body inserted endoscope cocted via a fiber optic bundle to a photographic lens carrier in a focusing mount. The photographic lens is provided with a compound sliding mount which positions it on a camera back supporting a self developing film plate in the focal plane of the lens. By moving the compound mount, a plurality of photographs may be obtained on a single self developing plate such that timely diagnosis may be readily facilitated.
Claims5
An endoscopic photographic system for examining and recording the appearance of body cavities comprising in combination:
- endoscopic optical means for insertion at a plurality of predetermined locations within a body cavity;
- light conducting means connected to said endoscopic optical means for providing a light conducting path therefrom to the exterior of the body cavity;
- lens and shutter means attached to said light conducting means for formation and timed transmission of an optical image of the view of each predetermined location within the body cavity transmitted via said endoscopic optical means and said light conducting means;
- a camera back for positioning a single self developing film plate to receive each of said optical images formed and transmitted by said lens and shutter means;
- and
- movable lens mount means positioned between said lens and shutter means and said camera back for producing a plurality of photographic images on said single film plate, each of said photographic images corresponding to one of said predetermined locations within the body cavity, wherein said movable lens mount means includes:
- plate means attached to said camera back for establishing a light-tight closure therefor;
- first retaining means mounted about the peripherial edge of said plate means for providing edge retention thereon;
- an aperture centrally located in said plate means and surrounded by said first retaining means;
- movable first slide means having an aperture therein and held in sliding engagement with said plate means by cooperative edge retention by said first retaining means;
- second retaining means mounted on said first slide means and said second retaining means surrounding the aperture in said first slide means for providing edge retention thereon;
- and
- movable second slide means having an aperture therein and held in sliding engagement with said first slide means by cooperative edge retention by said second retaining means.
