Artificial and animal lung models initially were used to investigate the removal of foreign bodies from the tracheobronchial tree with the flexible fiberoptic bronchoscope. Different extraction instruments (claw, basket, forceps, and balloon catheter) were passed separately through the channel of the bronchofiberscope, and tested for usefulness prior to human application. The Fogarty balloon catheter served as a valuable aid in dislodging impacted objects so that the operator could then grasp them with the claw, basket or forceps. The wire claw recovered many of the metallic and organic objects, the wire basket was successful in retrieving only the bulky objects and the forceps (ACMI) was effective in capturing all of the metallic foreign bodies. These techniques, developed in our laboratory, are now being used to augment rigid bronchoscopy in the removal of foreign bodies from adults and older children. At the present time fiberoptic foreign body removal is not recommended for pediatric cases because of the small diameter of the trachea and glottis in infants and young children.
人工肺模型和动物肺模型最初被用于研究使用可弯曲纤维支气管镜从气管支气管树中取出异物。不同的提取器械（爪形器械、篮形器械、镊子和球囊导管）分别通过纤维支气管镜的通道，在应用于人体之前测试其有效性。Fogarty球囊导管在松动嵌塞物体方面起到了重要辅助作用，这样操作者随后就可以用爪形器械、篮形器械或镊子抓住它们。金属丝爪形器械取出了许多金属和有机物体，金属丝篮形器械仅成功取出了体积较大的物体，而（ACMI公司的）镊子有效地捕获了所有金属异物。这些在我们实验室开发的技术，现在正被用于辅助硬质支气管镜从成人和大龄儿童中取出异物。目前，由于婴幼儿气管和声门直径较小，不建议对儿科病例采用纤维支气管镜取异物的方法。
