Abstract
An autoclavable endoscopic optical coupler includes the capability to optically couple an endoscope and a camera, so that a focused image will be communicated to the camera head. Furthermore, the coupler has the capability of withstanding multiple autoclave sterilization treatments without allowing moisture to penetrate the interior. The coupler includes a lens holder assembly that has an endobody on one portion and a second portion that is inserted into and coupled to a coupler body. The coupler body has a camera attached at one of its ends. A focus ring is physically coupled to the coupler body, which is coupled to the lens holder assembly. Turning the focus ring causes a translation motion of the lens holder assembly and endoscope with respect to the camera head.
