Abstract
Abstract A sterile connector and video camera cover is provided including a connector assembly for connecting a sterile endoscope to an unsterile surgical camera and a light fiber cable. The camera cover is extendable over the camera, its trailing cables and the light fiber cable. The connector assembly includes a coupling and a light fiber connection. The coupling includes a transverse window providing a sterile barrier and an optically clear path for light to pass through. The light source connection is mounted on the connector assembly enabling a light fiber cable to be optically coupled with the fiber optics of an endoscope. The coupling and the light source connector have a common exterior surface and are housed within the connector assembly. An adapter is provided enabling connection of the connector assembly with endoscopes having either threaded connections or compression-type fittings. A slot is provided on the connector assembly to engage a ball detent of the camera to ensure the camera remains rigidly fixed during use. A sterile disposable wand is attachable to the end of the connector assembly receiving the endoscope. This wand aides in connection of the camera to the coupling and is removed so that the endoscope can be attached to the coupling.
