<P>PROBLEM TO BE SOLVED: To provide an intubating equipment to lacrimal duct allowing the confirmation of a state of a tube inserted, which solves problems: that a bypass may be formed by a case that when a bougie is inserted to a lacrimal duct to forward the lacrimal duct, the bougie breaks through the wall of the lacrimal duct, progresses without correction and returns to the original duct again; that furthermore when the bougie is pulled out and a tube is inserted to the lacrimal duct using a stylette, the tube may by inserted to the bypass; that when the stylette is pulled out, the tube remains in the bypass; and that the another tube is inserted to the lacrimal duct from another punctum and total of two tubes are inserted to the lacrimal duct, therefore the state even one tube remains in the bypass, impedes correct treatment of the lacrimal duct: in treatment of lacrimal duct obstruction. <P>SOLUTION: The intubating equipment to lacrimal duct is equipped with a couple of tubes 2a and 2b which is to be inserted to the lacrimal duct and has a prescribed length and flexibility. A mark 9 for confirming insertion to the bypass formed to the lacrimal duct is provided to only one of the tubes. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
