Main endoscope parts are following three, these are important for almost all type of endoscopy.
The Insertion tubes:
Flexible shaft: This transmits the tip's push, pull, and force powers. Circling is vulnerable, especially during a colonoscopy. Continuous advancements, such as the now-commonly available variable solidity and the new over tube Endoscopic Guide, have given endoscopists greater control over circling prevention and patient annoyance reduction.
Bending section: By spinning the avoidance wheels, the tip may move up, down, left, and right, allowing it to go up, down, left, and right.
The Hand pieces:
Selection wheel endoscope tip up / down (large wheel): this wheel moves the tip of the endoscope up and down. The result of significantly lower the wheel of the endoscope at angles up and opposites in the endoscopic photograph. Even more confusing, the endoscope actually turns down real 3D, but in the opposite direction due to the way the optical and visual images are synchronized.
Descriptor F is a redirect up / down lock: To lock the wheel, turn the bolt in the other direction. The endoscopist may then keep the wheel in the proper position. This is more common during endoscopic treatment / special biopsy.
The Umbilical cord:
This consists of a flexible cylinder that houses all of the channels. The air/water port, pull port, spill test port, light aide, and electrical connector are all located at the string's end, which connects to the processor.
