Abstract

This instrument is an adaptation of the principle of the nasopharyngoscope to bronchoscopy. This bronchoscope has a slot in the distal end which holds the endoscope in place but which is not deep enough to prevent it being passed beyond the end of the bronchoscope.

The endoscope is longer than the bronchoscope, which allows the distal end to be passed into regions too small for the bronschoscope to enter. This excessive length also removes the eyepiece and battery connection from the proximal end, allowing the use of grasping forceps to better advantage.

The endoscope employs the system of lenses used in the nasopharyngoscope, giving an erect, magnified image, except that the terminal lens is so set
