<P>PROBLEM TO BE SOLVED: To provide a rigid endoscope that can include a conduit that flows a fluid to wash an observation window disposed at the distal end of the insertion part of the rigid endoscope without enlarging the diameter of the insertion part, and in which the washing of the conduit is unnecessarily or can be easily performed. <P>SOLUTION: An air feed/liquid feed tube 200 is detachably disposed in an endoscope body 40 of the rigid endoscope 10. The air feed/liquid feed tube 200 forms a conduit that circulates a cleaning solution and a gas to wash the observation window disposed at the distal end of the insertion part 44 of the endoscope body 40, and is chiefly disposed by being engaged with a groove 86 for the conduit formed in the insertion part 44. <P>COPYRIGHT: (C)2013,JPO&INPIT |
