<p>A medical probe device (21) comprising an elongate member (22) having proximal and distal extremities (22a, 22b) and first and second lumens (148, 28) extending from the proximal extremity (22a) to the distal extremity (22b). An opening (153) is provided in the distal extremity (22b) of the elongate member (22) in communication with the first lumen (148). A handle (29) is mounted on the proximal extremity (22a) of the elongate member (22a) for introducing the distal extremity (22b) of the elongate member (22) through the natural body opening into the canal. A scope (86) is positioned in the elongate member (22) and has a field of view which extends forwardly of the elongate member (22). A fitting (166) is coupled to the elongate member (22) for permitting a liquid to be suplied to the first lumen (148) and out the opening (153) to provide a clear field of view for the scope (86). The elongate member (22) is provided with at least one additional opening (182) proximal of the first named opening (153) in the elongate member (22) and in communication with the second lumen (28) for permitting aspiration of the liquid while liquid is being introduced through the first named opening (153) in the elongate member (22).</p> |
