Lacrimal duct obstruction or narrow and then smooth, is an important part of the treatment of lacrimal diseases, but also a necessary condition for physiological healing; to prevent the overflow of tears, the formation and excretion of tears in the eye surface to maintain a protective dynamic physiological balance. In order to simplify the surgical method, shorten the course of treatment, easy to popularize, so there have been many new surgery. So many patients with tearing get reasonable and effective treatment. Our hospital homemade drilling needles, lacrimal duct for negative pressure drilling, and then the effect of lacrimal passage is more satisfactory, the treatment is also shortened. The initial report is as follows: for fellow reference and correction. First, the production of drilling needle Take take the 7,8,9 needle, remove the needle bevel, with a 45-degree angle of the triangular needle or dental root canal drill, as far as possible to expand the inner edge of the needle, so that the needle-shaped conical cavity , And then use whetstone polish the outer edge of the needle, so pinhole Park sharp mouth. Needle No. 7 is used for stenosis or obstruction of the lacrimal duct, needle No. 8 is used
