Types of Endoscopes
-
The markets for endoscopes are divided into three major catagories: the medical profession, veterinary profession and all other uses are lumped under general industry (both private and public, business, etc.). The latter includes law enforcement, which, for example, may use endoscopes in customs operations, and the aviation industry can use them to look into parts, such as turbines. Endoscopes may be used in machinery inspection in all industries. However, most people think of endoscopes in medical uses. Doctors classify their endoscopes by procedures. Therefore, those used in gastrointestinal investigations would be called a gastroscope, colonoscope or sigmoidoscope, depending on the procedure. As well, doctors have scopes that look into airways or are used in urological procedures. Veterinarians would have similar scopes for their animal patients.
Inside an Endoscope
-
An endoscope may be rigid or flexible, and functions via two-fiber optic lines--one for a light source and the other for visuals. Endoscopes also have an additional port for administering drugs, for suction or irrigation. They also can be used to insert small surgical tools. Endoscopes often are used in conjunction with a camera or other recording equipment. Newer endoscopes have digital capabilities that allow the doctor to enhance the image.

Super CCD Endoscope
-
This fully digital endoscope uses the super CCD (charge-coupled device) chip to enhance image magnification, clarity and color. Because the super CCD chip is 45 percent smaller than other high-resolution CCDs, the super CCD endoscope has a smaller diameter than other high-magnification endoscopes. This endoscope transmits magnified images to a monitor. The technology behind it incorporates an RGB filter to generate superior color images. As well, the design of the super CCD cuts back on image noise, allowing for clearer frozen pictures. In video mode, it processes 30 frames a second, thus producing smooth images that flow naturally.
