Laryngoscope with Miller blade. A laryngoscope is a rigid instrument used to examine the larynx and to facilitate intubation of the trachea. It is composed of two separate parts: the handle (which also contains the battery) and the blade, which is used to move the tongue and soft tissues aside to reveal a view of the larynx. An incandescent bulb can be found on the blade tip - it turns on when the blade is attached to the handle and locked into the 90 degree position to illuminate the larynx.
