Abstract
A hand-held viewing system for use during medical procedures including endotracheal intubations or tracheostomies is disclosed. The viewing system includes an endoscope assembly having a fiber optic bundle for indirectly viewing the tracheal area of a patient into which the breathing tube is being inserted and a malleable sheath on the endoscope assembly for guiding the tube into place within the patient's trachea. The viewing system also incorporates an adapter stop which allows the endoscope assembly to be used with breathing tubes of varied lengths. A handle is included to which the endoscope assembly and a viewing means are removably connected.
