n. an instrument used to look into the trachea and bronchi. In addition to the rigid tubular metal type, used for many years, there is now a narrower flexible fibreoptic instrument with which previously inaccessible bronchi can be inspected. With either instrument the bronchial tree can be washed out (see bronchoalveolar lavage) and samples of tissue and foreign bodies can be removed with long forceps. —bronchoscopyn.
