ABSTRACT:
Three embodiments of an improved endoscope: The first embodiment is composed of a flexible tube member, the proximate end portion of which is attached to and in optical communication with a control unit; and, a second flexible tube member partially circumscribing the first tube member, one terminal end portion of which is (i) affixed to the outer surface of the first flexible tube at a point other than the distal portion and (ii) adapted to expand and contract along its own and the longitudinal axis of the first flexible tube member. The second embodiment contains a control unit, first, second and flexible tube members and in addition a third tube member. The third tube member has (i) a terminal portion affixed to the first tube member at a point other than at a distal portion and (ii) the balance thereof spaced apart from and circumscribes a part of the first and a portion of the second flexible tube member. One terminal free end of the second flexible tube is slideably received within the third tube member. The third embodiment contains a control unit, first and second flexible tube members; the second flexible tube member is not attached to the first flexible tube and has a terminal end portion composed of an outward flaring sidewall forming an angle with the longitudinal axis of the balance of the second flexible tube.
