Endoscope: A lighted optical instrument that is used to get a deep look inside the body. An endoscope, which may be rigid or flexible, can be used to examine organs, such as the throat or esophagus. Specialized endoscopes are named for where they are intended to look. Examples include the cystoscope (bladder), nephroscope (kidney), bronchoscope (bronchi), laryngoscope (larynx), otoscope (ear), arthroscope (joint), laparoscope (abdomen), and gastrointestinal endoscopes.
