Common areas of medical uses include: bronchoscopy, colonoscopy and viewing of the upper gastroenterological systems. Endoscopies are commonly used for the diagnosis of cancer. Recent video-endoscopes with high costs can only be used in the department of endoscopy and the patients from CCU or ICU that need endoscopy should be transported there.

The main components of portable and digital video endoscope are:

A flexible tube.

A light that illuminates what the doctor wants to examine. The light is delivered via an optical fiber system.

A high quality CCD system that transmits an image to the viewer from the fiberscope.

Another channel to allow the entry of medical instruments or manipulators.

Hand touch monitor and control center

The device consists of a flexible endoscope tube with an integrated video chip (CCD) which is located in the endoscope tip as well as a video controller-monitor. The hand touch monitor allows us to freeze, mark and save high quality taken pictures. The endoscope is very easy to control.
