Abstract
An adapter for an endoscopic system. An ocular piece is suitable for substitution for the eye-piece of a conventional endoscope. The ocular piece includes a window that is fitted into the end of a barrel-like member and slightly recessed from the edge thereof. The endoscope-engageable portion of the adapter includes a similar window that is also recessed creating a thin cavity therebetween. A latch mechanism at the end of the endoscope engageable portion of the adapter includes a plate having an interior circular aperture that can be selectively moved between positions that block and permit axial travel between the ocular piece and the endoscope engageable portion. The thin chamber between the windows is filled with sterilized water, preventing loss of optical clarity from the accumulation of liquid particles on window surfaces. The separtion between the windows permits rotation therebetween without damage to optical surfaces.
