TRACHEOSCOPE AND BRONCHOSCOPES FOR USE WITHOUT A LARYNGOSCOPE

Arch Otolaryngol. 1928;7(6):634-636. doi:10.1001/archotol.1928.00620010662013
Abstract

The tracheoscope that I shall describe was designed because all the available ones were too short. The tracheoscopes are so short that when introduced through the laryngoscope they are retained in place with considerable difficulty while the laryngoscope is being withdrawn. Therefore, a longer tracheoscope was designed to overcome this difficulty. It was at first intended that the tracheoscope should be used with the aid of a Jackson or a Mosher laryngoscope, but because of the ease with which the instrument was regularly passed through the anesthetized larynx without a laryngoscope it was decided to dispense with the laryngoscope. Because of the facility with which the tracheoscope could be passed in this manner, a 5 mm. and a 7 mm. bronchoscope were also made.
