Endoscopes are a type of tubing and camera combination used by doctors to see inside the body. They provide the ability to reach places that may not be seen by x-rays and other such means. These medical imaging devices are available in many sizes to suit different purposes. Different types of endoscope cameras are used for different areas of the body. Upper endoscopes, bronchoscopes, colonoscopes, sigmoidoscopes, and many other endoscopes are named for the areas where they are used.

Endoscope cameras are tubing that has a camera attached to the end. The tubing can be flexible or rigid depending on the area it will be used. A camera transmits images to monitors that provide doctors with an up close view of everything in front of the camera.

Upper endoscopes are endoscope cameras that are used to view the top section of the small intestine, the stomach, and the esophagus. For this endoscope, a flexible tube is used to provide easy navigation with minimal discomfort for the patient. Doctors use upper endoscopes when they are looking for lesions or other damage in the area. In some cases, the endoscope allows doctors to remove tissue samples for testing.


Endoscope cameras designed for the trachea and bronchi are called bronchoscopes. The tubing for this endoscope can be rigid or flexible. Rigid tubing is used for specific types of hemorrhages and lesions or to remove a blockage. Flexible tubing is used primarily for diagnosing and surgical endoscopy.

Colonoscopes are endoscope cameras that are designed for the large intestine or colon. Flexible tubing is used for this scope, and doctors use it to diagnose problems in the lower digestive area. Many digestive disorders are difficult to diagnose without using an endoscope. Colitis, polyps, and cancer can be found through colonoscopy procedures.

Similar to a colonoscope, sigmoidoscopes are also used for the digestive tract. This scope is used for the bottom third of the large intestine. Doctors generally use the sigmoidoscope to diagnose bowel problems, such as unusual bleeding. It can also be used to screen and diagnose colorectal cancer.

Endoscope cameras are beneficial pieces of medical equipment. They are versatile enough to be used as both diagnostic and treatment instruments. These cameras provide visual imaging as a means of replacing unnecessary or exploratory surgery. With the availability of several options, doctors can choose the best endoscope for each area of the body.
