Katena cannula K7-3016 (Katena Products, Inc, Denville, NJ) is a 23-gauge cannula that features an end-opening port for direct irrigation and a tapered tip for ease of entry into an undilated punctum. The 13-mm length makes it ideal to probe as well as irrigate the proximal lacrimal system. Katena cannula K7-3016 eliminates the need for punctal dilation and placement of Bowman probes to dilate the punctum and measure canalicular obstruction, respectively. The end-opening, direct irrigation design prevents misdiagnosis in the setting of canalicular stenosis.
卡特纳K7 - 3016套管（卡特纳产品公司，新泽西州丹维尔）是一种23号套管，其特点是有一个用于直接冲洗的开口端口和一个便于进入未扩张泪小点的锥形尖端。13毫米的长度使其非常适合探查和冲洗近端泪道系统。卡特纳K7 - 3016套管分别消除了泪小点扩张以及使用鲍曼探针扩张泪小点和测量泪小管阻塞的需求。开口式直接冲洗设计可防止在泪小管狭窄情况下出现误诊。
