PROBLEM TO BE SOLVED: To provide a lacrimal duct tube having a mark installed to recognize to which the lacrimal duct tube is shifted, the upper lacrimal point or the lower lacrimal point, and find which terminal is pulled for restoration, although the lacrimal duct tube is deviated to the upper lacrimal point or the lower lacrimal point in indwelling the lacrimal duct tube in the lacrimal duct over a long period of time in the lacrimal reconstructive surgery.SOLUTION: It is possible to simply recognize to which a tube 64 is deviated, the upper lacrimal duct or the lower lacrimal duct by using the lacrimal duct tube where the marks are put on both sides within 1.5 cm from the central point and the marks are asymmetrical about the central point 69. Further, marks are put on the tube terminals 66, 68 as well, whereby it is possible to simply recognize which terminal is pulled for restoration. Therefore, it is very convenient to continue long medical treatment. |
