目的： 评价新型硅胶管(RS一次性使用泪道引流管)治疗泪小管断裂的临床效果。

方法： 回顾性研究。收集2013-01/2015-10来我院就诊的47例47眼泪小管断裂患者完整的临床资料。在泪小管断裂吻合术中，新型硅胶管从上、下泪小点 “U” 形置入，在泪道中保留3mo。拔管后，观察泪道通畅率、是否伴有泪溢和其他并发症发生情况。

结果： 所有患者，泪小管吻合成功，新型硅胶管顺利植入。未发生硅胶管相关的并发症，如眼部刺激、泪小点外翻和撕裂、过早脱落等。治愈41例(87%)，泪道冲洗通畅，无泪溢。部分治愈4例(9%)，患眼轻微泪溢，但泪道冲洗通畅。失败2例(4%)，患眼泪溢，泪道冲洗不畅。

结论： 在泪小管断裂吻合术中，新型硅胶管是一种安全、有效、无创的置入物，其操作过程简单，易于掌握，术者学习曲线短。

METHODS: This was a prospective clinical study. Data were analyzed from 47 eyes of 47 patients presenting with traumatic canalicular laceration in our hospital from January 2013 to October 2015. The newly designed silicone tubes were inserted through the lacrimal punctum and left in the bicanaliculi for 3mo. Data of the lacrimal duct patency, epiphora, and eyelid shape were recorded.

RESULTS: Surgery was performed successfully in all cases. No complications associated with the silicone tubes occurred. In total, 41 patients(87.23%)achieved complete success, 4 patients(8.51%)achieved partial success, and 2 patients(4.26%)had surgical failure.

CONCLUSION: The newly designed silicone tube is an effective and atraumatic tool for the management of canalicular lacerations. The operation process is simple, and is easy to grasp for the surgeon.
