The endoscope is a testing instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. One has an image sensor, an optical lens, a light source illumination, a mechanical device, etc. It 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 show, so it is very useful for doctors. For example, an endoscopic doctor can observe ulcers or tumors in the stomach and formulate the best treatment plan accordingly.

Endoscope Introduction

The endoscope is a tube equipped with light. The endoscope can enter the body through the natural orifice of the body or a small incision made by surgery.

The original endoscope was made of rigid tubes and was invented more than 100 years ago. Although they have gradually improved, they are still not widely used. Later, in the 1950s, the endoscope was made of a soft tube, so that it 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 vision clearer. Today's endoscopes usually have two fiberglass tubes, and light enters the body through one of them. Looking through another tube or through a camera, some endoscopes even have miniature integrated circuit sensors that feed back the observed information to the computer.

Some procedures can be done with endoscopes and lasers. The endoscope's fiber optics can deliver laser beams, burn vegetation or tumors, and close blood vessels.
