Quick-release endoscopic coupling assembly

Abstract

There is provided a quick-release coupling assembly for an endoscopic ocular, the assembly including an ocular mounting surface having an aperture and a longitudinal axis preferably passing through the center of the aperture on the mounting surface. A stationary guidewall is preferably radially spaced from and substantially concentric with the aperture of the ocular mounting surface, and the guidewall at least partially encircles the aperture to define an alignment recess adjacent the mounting surface for receiving the proximal end of an endoscopic ocular. At least one gripping jaw is provided for axial reciprocation and having a clamping position and a release position. The jaw comprises an inner tab which extends outwardly from the mounting surface, a retainer flange extending radially inwardly, and an engagement surface which may preferably be angularly disposed relative the axis. When reciprocated to the release position, the engagement surface is outside of the alignment recess, and when reciprocated to the clamping position, it can engage a portion of the proximal end of an ocular eyepiece positioned within the alignment recess. In a preferred embodiment, the assembly includes a pair of oppositely disposed gripping jaws for releasably engaging the proximal end of an ocular to be coupled. The engagement surface of the jaw may also include a tapered lip to readily accommodate ocular eyepieces of various sizes and shapes.
