本文报告在白内障囊外摘出术中用一种新型冲洗插管娩出晶体核的方法。冲洗插管系由一个能配备冲洗柄的20号针和一个能插在针上的浅盘构成。在针的前端连接一个小的浅盘,盘的大小约4×4mm,厚1.0～1.2mm,盘底面的曲率半径为10mm。针的前端与盘连接,呈90°角,盘的终端设有一个流水口,在流水口的对面有一个短的控制片由盘底伸出,与盘底约呈135°角,
This article reports a method of delivering a crystalline nucleus using a new irrigation cannula in extracapsular cataract extraction. The irrigation cannula consists of a 20 gauge needle that can be equipped with a flush handle and a shallow plate that can be inserted over the needle. A small shallow dish is connected to the front end of the needle. The size of the dish is about 4 × 4 mm and the thickness is 1.0 to 1.2 mm. The radius of curvature of the bottom surface of the dish is 10 mm. The front end of the needle is connected to the pan at an angle of 90 ° and the end of the pan is provided with a water outlet with a short control blade projecting from the bottom of the pan opposite the water outlet with an angle of about 135 ° to the bottom of the pan,
