ABSTRACT:
An endoscope includes a forceps-control member movably mounted in a forward region of the elongate portion which is adapted to be inserted into a body cavity for selectively projecting and retracting forceps from and into the forward region of the insertion portion and an operating wire having one end connected to the forceps-control member and extending to the manipulator unit through an operating wire guide tube such that the projection and retraction of the forceps is controlled from the manipulator unit through the displacement of the operating wire. Apparatus for cleaning and/or sterilizing the operating wire guide tube includes a control shaft guide tube connected to the wire guide tube, a tubular control shaft mounted for movement within the control shaft guide tube, the control shaft being connected to the other end of the operating wire, a fluid passage provided in the tubular control shaft communicating with the control shaft guide tube, a flexible tube one end of which is connected to the tubular control shaft and communicating with the fluid passage, the flexible tube including a slackened length portion, and a fluid inlet externally provided on the manipulator unit of the endoscope, the other end of the flexible tube communicating with the fluid inlet.
