A sterile endoscope with a rigid inserted portion intended for the visual examination and treatment of the anus and rectum. It is inserted into the body through the anus during anoscopy. The inserted portion is short in length, though longer than a sphincteroscope, and large in diameter, and an obturator is typically inserted into its lumen to assist the insertion. The anatomical images are illuminated by a light source and can be viewed by the user through relayed lens optics or direct vision. This device is commonly used to examine/diagnose patients suffering pain in the rectum/anus, haemorrhoids, or anal fissures. This is a single-use device.
