Abstract:

An eyepiece assembly for an endoscope focusable by an exterior focusing collar is made soakable by using an O ring and very fine screwthreads to prevent liquid sterilant from penetrating under the collar and entering the interior of the eyepiece. The use of an O ring also provides a uniform resistance to the turning of the focusing collar and makes the focusing adjustment shock resistant. In another aspect of the invention, the placement of the light fiber connector on the discardable stop housing improves light transmission and allows one-handed focusing of the eyepiece.
