鼓膜穿刺是耳科临床常用的操作。如何固定穿刺针,常使操作者为难,操作中常需助手持针固定。这样固定不稳,抽液不彻底,操作起来很不方便。为此,作者设制了一种鼓膜穿刺耳镜。一、结构组成此镜由下述部件组成:(1)大、中、小号的窥耳镜;(2)穿刺针固定片;(3)穿刺针固定夹;(4)缓冲耳塞;(5)缓冲鼓膜穿刺针;(6)橡皮带(图1)。二、制作方法 1.于窥耳镜圆形底端垂直锯成两个对称的深0.5cm、宽0.2cm缺口a、b(图2)。 2.根据a、b两缺口的宽度用有机玻璃或金属制成凸形固定片1个,将其嵌入a、b Tympanostomy is commonly used in otology. How to fix the puncture needle, often make the operator difficult, often need to help hand-held needle fixation. This fixed instability, pumping fluid is not complete, very inconvenient to operate. To this end, the author set up a tympanic laparoscopic otoscope. First, the structure of the mirror consists of the following components: (1) large, medium and small peeping oscope; (2) puncture needle fixed piece; (3) needle clip; (4) buffer earplugs; ) Buffer tympanic membrane needle; (6) rubber band (Figure 1). Second, the production method 1. At the bottom of the circular microscope saw the endoscope perpendicular to the two symmetrical deep 0.5cm, 0.2cm wide gap notch a, b (Figure 2). 2. A, b according to the width of the two notches made of plexiglass or metal convex fixed piece, it is embedded in a, b
