Reusable, sterile covering for a surgical camera

摘要

A sterile covering enabling an endoscope to be attached to or detached from a camera coupling without contamination by either the camera or the coupling. The sterile covering encloses the camera and is disposed within a cavity of a C-mount coupling which couples the endoscope to the camera. The covering includes a system for registering an optically clear portion of the covering, an optically clear film, or an element coupled to the covering with the endoscope-to-camera optical path. In one embodiment, the same system which establishes optical registration also enables attachment of the covering to the C-mount coupling, thereby providing an optically clear, fluid-impermeable barrier between the endoscope and the camera, and eliminating possible contamination of the endoscope by either the C-mount coupling or the camera.
