ABSTRACT:
A connector for coupling an endoscope to a video camera to facilitate an enhanced viewing of endoscope-invaded examination and surgical zones on a video monitor screen, to which the camera perceived image is transmitted. The coupler combines three axially-aligned and rigidly joined component elements including a first adapter for quickly and easily connecting and disconnecting an endoscope, and a second adapter for connection to a video camera. A joinder element is interposed between and connects the two adapters to one another. The three components of the coupling apparatus are fixed against rotation relative to one another, while the first adapter permits rotation of the endoscope with respect to the coupling apparatus and the attached camera. Fluid-tight seals are provided between the elements of the coupling apparatus and between its adapters themselves and endoscope and camera. The joinder element houses a longitudinally positionable lens or lens system for focusing images received from the endoscope, onto the focal plane of the video camera.
