Endoscopic adapter with lamina interface
First Claim
1. In an endoscopic adapter of the type that includes an elongated adapter body having opposed ends, a first end being arranged to engage a camera head and a second end being arranged to engage an endoscope, the improvement comprising, in combination:
- a) an ocular piece;
b) a chamber member having opposed open and closed ends for receiving said ocular piece;
c) means for fixing said ocular piece to the proximal end of said endoscope;
d) said piece including a first substantially planar window located at an end thereof adjacent said closed end of said chamber member;
e) said chamber member including a second substantially planar window;
f) said first and second windows being substantially aligned along the optical axis of said adapter; and
g) said first window being recessed into said ocular piece and said second window being recessed into said closed end of said chamber member to define a substantially planar cavity therebetween.

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.
