Abstract
The electronically foot-switch controlled irrigation/aspiration instruments have several disadvantages due to the big 'dead space' between the pump and the aspiration cannula. A new high precision fingertip controlled aspiration system is described. A specially designed ball valve connects the aspiration cannula directly to the vacuum reservoir, thereby almost eliminating the dead space. The system is nonelectric, it has no moving parts, it is easy to operate and highly cost efficient.
摘要
电子脚踏开关控制的冲洗/吸引器械存在一些缺点，因为泵和吸引套管之间存在较大的“死腔”。本文描述了一种新型的高精度指尖控制吸引系统。一种特殊设计的球阀将吸引套管直接连接到真空储液器，从而几乎消除了死腔。该系统无需电力，没有活动部件，操作简便且成本效益高。
