History Of Medical Application Of Medical Endoscope

The world's first endoscope was created in 1853 by a French doctor, De Somio. An endoscope is a commonly used medical device. It consists of a head end, a bending part, an insertion part, an operation part, and a light guide part. When in use, the light guide part of the endoscope is first connected to the matching cold light source, and then the insertion part is introduced into the pre-examined organ, and the control operation part can directly peep the lesions of the relevant parts.

The earliest endoscopy was used for rectal examination. The doctor inserts a hard tube into the patient's anus and observes the lesions of the rectum with the help of the light of the candle. The diagnostic data that can be obtained by this method is limited, the patient is not only very painful, but also the risk of perforation is very high due to the hard instruments. Due to these shortcomings, endoscopy has continued to be applied and developed, and many different uses and types of instruments have been gradually designed.

In 1855, the Spaniard Cahesa invented the laryngoscope. The German Heimann von Haimoz invented the ophthalmoscope in 1861.

In 1878, Edison invented the light bulb, especially after the appearance of the miniature light bulb, the endoscope has been greatly developed, and the temporary arrangement of the surgical endoscopy can also reach a very precise level.

In 1878, German urologist M. Nitz created the cystoscope, which can be used to examine certain lesions in the bladder.

In 1897, the German brother Killian conceived the bronchoscope.

In 1862, the German Small created the esophagoscope.

In 1903, American Kelly created the proctoscope, but it was not widely used until after 1930.

In 1913, the Swedish Jacobs reformed the method of pleuroscopy.

In 1922, American Schindler founded the gastroscopy method.

In 1928, the German Kalk created the laparoscopic method.

In 1936, the American Skafe conducted a ventriculoscopy test, and it was not until 1962 that the Germans Guau and Frestier founded the ventriculoscopy method. Since then, a whole series of microscopic examination methods have been formed.

In 1963, Japan began to produce fiberscopes,

In 1964, the biopsy device of fiber endoscope was successfully developed. This special biopsy forceps for biopsy can have suitable pathological materials and is less dangerous.

In 1965, the fiberoptic colonoscope was made, which expanded the scope of examination for lower gastrointestinal diseases.

In 1967 began to study magnifying fiber endoscope to observe fine lesions. Fiber optic endoscopes can also be used to perform in vivo assays, such as measuring in vivo temperature, pressure, displacement, spectral absorption, and other data.

In 1973, laser technology was applied to endoscopic treatment, and gradually became one of the means of endoscopic treatment of gastrointestinal bleeding.

In 1981, endoscopic ultrasound technology was successfully developed. This new development, which combines advanced ultrasound technology with endoscopy, has greatly increased the accuracy of disease diagnosis.
