Summary
A laryngoscope is a medical instrument that is used to get a view of the voice box and the space in between the vocal cords. A laryngoscope is used to place a breathing tube into the trachea (windpipe or airway) to protect the patient's airway and provide a way to help a person breathe during surgery; this is called intubation.
