A laryngoscope is a medical instrument used by doctors to examine the throat and vocal cords. It consists of a long handle and a blade that helps to lift the tongue and provide a clear view of the larynx, which is the part of the throat that contains the vocal cords. This tool is essential during procedures like intubation, where a tube is inserted into the airway to help a patient breathe. Laryngoscopes come in various types, including flexible and rigid versions, each suited for different medical situations. They are commonly used in emergency rooms, operating rooms, and during anesthesia to ensure that patients can receive the necessary care safely.
