Attorney, Agent or Firm: Fields, Lewis & Rost
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. |

DETAILED DESCRIPTION I claim: 1.
An apparatus for enclosing an unsterile, miniature video camera and its trailing cables and a light fiber cable in a sterile cover and for connecting the camera and the light fiber cable to a sterile endoscope having a separable light guide fitting, said apparatus comprising: a connector assembly for attachment of the camera to the endoscope and for attachment of the light fiber cable to the light guide fitting, said connector assembly including: a generally cylindrical coupling having a first end for receiving the camera and a second end for receiving the sterile endoscope; a transparent window positionable between said first and second ends of said coupling for providing a sterile and optically clear barrier between the camera and endoscope; means for aligning the camera within said first end of said coupling in a fixed position; and light fiber connecting means mounted to said coupling, said connecting means having a first end for receiving the light fiber cable, and a second end for receiving the light guide fitting of the sterile endoscope; and a flexible sterile cover attachable to said connector assembly and extendable over the camera, the trailing camera cables and the light fiber cable.
2.
An apparatus, as claimed in claim 1, further including: means in said first end of said coupling for rigidly stabilizing said camera within said cylindrical housing.
3.
An apparatus, as claimed in claim 1, wherein said light fiber connecting means includes: a connector tube having first and send ends; and a threaded portion positionable between said first and second ends of said connector tube.
4.
An apparatus, as claimed in claim 1, further including: a sterile disposable wand attachable to said second end of said coupling, said wand stabilizing said apparatus when connecting the camera thereto.
5.
An apparatus, as claimed in claim 1, further including: an adaptor removably attachable to said second end of said coupling for interchangeable connection with the sterile endoscope
