endoscope
Tube with camera
An endoscope is a medical instrument—a thin, flexible tube with a light and camera—inserted into the body to view internal organs or cavities.
Doctors use endoscopes to examine the digestive tract, airways, or joints without major surgery: The gastroenterologist used an endoscope to check for ulcers.
The procedure is called endoscopy.
