I devised a new spatula needle (DO-5) that improves the performance of the established DO-1 needle of the Davis and Geck Co. The diamond-shaped tip of the needle was lengthened to improve its penetration force through the sclera and the widened shoulder of the point was narrowed to enable the needle to pass through the sclera more easily and to provide closer contact between suture and scleral tissue.
我设计了一种新的铲形针（DO-5），它改进了戴维斯和格克公司已有的DO-1针的性能。针的菱形尖端被加长，以提高其穿透巩膜的力量，针尖加宽的肩部变窄，使针能更轻松地穿过巩膜，并使缝线与巩膜组织之间的接触更紧密。
