The Endoscope Is A Tube With Lights
Jul 20, 2018

The endoscope is a tube equipped with a light that can enter the body through the body's natural channels or through small incisions made by surgery.

The original endoscope was made of hard tubes and was invented more than 100 years ago. Although they have gradually improved, they have still not been widely used. Later, in the 1950s, endoscopes were made of soft tubes, so they could be easily bent at the corners of the human body. In 1965, Harold Hopkins installed a lenticular lens on the endoscope to make the field of vision clearer. Today's endoscopes usually have two fiberglass tubes through which light enters the body. Observations are made through another tube or through a camera, and some endoscopes even have micro-integrated circuit sensors that feed back the observed information to the computer.

The endoscope is a test instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. One has an image sensor, an optical lens, a light source illumination, a mechanical device, etc., which can enter the stomach through the oral cavity or enter the body through other natural channels. The endoscope can be used to see lesions that X-rays cannot display, so it is very useful for doctors. For example, an endoscopic doctor can observe ulcers or tumors in the stomach and develop an optimal treatment plan accordingly.
