Curettes, Biopsy, Bronchus, Endoscopic, Rigid
Definition : Endoscopic biopsy curettes designed to remove superficial tissue from the internal wall of the bronchial tree through a rigid endoscope (i.e., bronchoscope), usually under imaging (e.g., fluoroscopic, helical computed tomography) guidance. These curettes are typically manual instruments with a long stiff shaft; a distal working end that resembles a very narrow solid spoon with sharp edges and a size (typically less than 2 mm diameter) appropriate for introduction through the working channel of a rigid bronchoscope; and a proximal end with a mechanism that permits manipulation (e.g., flexion, rotation) of the working end. Rigid bronchoscopic biopsy curettes are typically used to obtain samples of large-diameter bronchi tissue and/or tumors.
