我们对3例下泪小管断裂患者,采取“管内穿线搭桥吻合法”获得良好效果,现将手术方法介绍如下: 1.创口处置:创口处滴1%地卡因溶液,清创消毒,再注射2%普鲁卡因。2.寻找泪小管残端:用线状刀插入上、下泪点扩大0.5m m,将泪道探针一端折成弧形,插入上泪点切口内,沿上泪小管→泪总管→下泪小管的弧行方向捻转探针另一端,由下泪小管远处残端穿出,将注射针 We have 3 cases of lacrimal duct rupture patients, to take the “tube stringing bridge anastomosis” to obtain good results, now the surgical methods are described as follows: 1. Wound treatment: Wound 1% dexamethasone solution, debridement and disinfection, re-injection 2% procaine. 2. Look for the canalicular stump: insert with a linear knife, the next tear point to expand 0.5mm, one end of the lacrimal probe bent into the arc, insert the punctate incision, along the lacrimal duct → tear duct → tear Twist the direction of the arc of the small tube twisting the other end of the probe, the lower end of the lacrimal canal puncture out through the stump, the injection needle
