以往我们在颅骨修补等需在骨缘处钻孔的手术中。常用普通脑压板垫于骨缘处来保护脑组织。此法有垫护深度不明确、钻头易滑脱等缺点。为此我们自制一种类似于脑压板的骨缘钻孔保护器,经临床应用证明此器械简便有效,现介绍如下。1 结构见附图。a、b 段各长为1.2 cm。为插入颅骨与硬膜间
In the past, we had to perform operations such as cranial bone repair on the margin of the bone. Common brain pressure pads are used to protect the brain tissue at the margin of the bone. This method has some disadvantages such as unclear depth of cushioning and easy slippage of drills. For this reason, we made a kind of bone edge drill protector similar to the brain pressure plate. The clinical application proved that this instrument is simple and effective. Now it is introduced as follows. 1 See the drawing for the structure. Each segment a and b is 1.2 cm long. For insertion between the skull and the dura mater
