取出盯聍栓或外耳道异物时,耵聍钩是必备工具之一。一般购用的盯聍钩,钩端较粗,不易从盯聍栓或异物的一边插入深部;因钩短,不易越过盯聍栓或异物直径的一半,常常滑脱或拉时使其打转,不易迅速一次钩出;且柄端粗大并呈方形,既影响视野,又转动欠灵活;又因质重,传导感觉不灵敏,易伤及外耳道壁或鼓膜。笔者用市售三棱头铜质卷棉子改制成盯聍钩,使用方便,兹介绍如下:制法:取一市售三棱头铜卷棉子,将棱磨去,尖头磨钝圆,将此端3.5毫米长一段先弯成与外耳道上壁大约一致的弧形,再将此弧形一段向弧之垂直方向拐90°
Snap hooks are one of the must-have tools when removing eye stabs or external auditory canal foreign bodies. Commonly used stare hook, coarse hook end, not easy to stare from the side of the stab bolt or foreign body into the deep; because the hook is short, not easy to stare through the stab bolt or foreign body diameter of half, often slipping or pulling to make it spin, not easy Quickly hooked; and the handle end of the large and square, both affect the field of vision, but also less flexible; but also because of weight, conduction feels insensitive, easy to hurt the external auditory canal wall or tympanic membrane.
