Deflecting endoscope

摘要

An endoscope including a flexible shaft having a distal end which can be deflected by a manually operable mechanism on a handle assembly. The shaft includes an elongate member having longitudinal fins that extend radially outward. A hollow lumen through the core member forms a fluid channel, and the radially extending fins provide channels for accommodating optical fibers and pull wires. The member has a substantially continuous cross-section enabling it to be inexpensively extruded.
