Who made the first endoscope?

The first endoscope in the world was created in 1853 by a French doctor, de Somio. Endoscope is a common medical instrument. It is composed of a flexible part, a light source and a group of lenses. When used, the endoscope is introduced into the pre-examined organ, and the changes of the relevant parts can be directly seen.

The earliest use of endoscopes was in rectal examination. The doctor inserted a hard tube into the patient's anus and, with the light of a candle, observed the lesions in the rectum. The diagnostic data available with this method are limited, and the patient is not only in pain, but there is a great risk of perforation due to the hardness of the instrument. Despite these drawbacks, endoscopy has continued to be used and developed, with many different applications and different types of instruments gradually being designed.

In 1973, laser technology was applied to the treatment of endoscopy, and gradually became one of the means of endoscopic treatment of gastrointestinal bleeding. In 1981, endoscopic ultrasound technology was successfully developed. This new development of combining advanced ultrasound technology with endoscope greatly increased the accuracy of the diagnosis of lesions.
