The world's first endoscope was created in 1853 by the French physician Desormeaux. Endoscope is a commonly used medical device. It consists of a head end, a bent part, an insertion part, an operation part and a light guide part. When using the endoscope light-guiding part to the matching cold light source, and then the insertion part into the pre-checked organs, control the operation part can directly peep at the relevant parts of the lesions.
The earliest endoscopes were used for rectal examination. The doctor inserted a rigid tube into the patient's anus and, with the help of the light of a candle, observed lesions in the rectum. The diagnostic information obtained by this method was limited, and the patient was not only in pain, but also at great risk of perforation due to the hardness of the instrument. In spite of these disadvantages, endoscopy has continued to be used and developed, and gradually many different uses and different types of instruments have been designed.
In 1855, the Spaniard Cahsa invented the laryngoscope. The German Heimann von Helmholtz invented the fundoscope in 1861.
In 1878, Edison invented the light bulb, especially after the emergence of the miniature light bulb, which led to a great development of endoscopy, and the temporary arrangement of surgical endoscopy can be achieved to a very precise degree.
In 1878, the German urologist M. Nitze created the cystoscope, with which certain lesions in the bladder could be examined.
In 1897, the German brother Kilian envisioned the bronchoscope.
In 1862, German Smoll created the esophagoscope.
In 1903, American Kelley created the proctoscope, but it did not come into general use until after 1930.
In 1913, Jacobs, a Swede, reformed pleuroscopy.
In 1922, the American Hindler created gastroscopy.
In 1928, the German Kalk founded the laparoscopy method.
In 1936, the American Scarf conducted ventricular microscopy test, until 1962, only by the German Gouaux and Freystier founded the ventricular microscopy method. From then on, a whole series of microscopy method was formed.
In 1963, Japan began production of fiber endoscopy,
In 1964, the development of fiber endoscopy biopsy device, this biopsy of the special biopsy forceps can have a suitable pathology and small danger.
In 1965, the fiberoptic colonoscope was made, which expanded the scope of examination for lower gastrointestinal diseases.
In 1967, research began on magnifying fiberoptic endoscopes to view microscopic lesions. Fiber-optic endoscopes can also be used for in vivo assays, such as measuring temperature, pressure, displacement, spectral absorption, and other data in the body.
In 1973, laser technology was applied to the treatment of endoscopy, and gradually became one of the means of transendoscopic treatment of gastrointestinal bleeding.
In 1981, endoscopic ultrasound technology was successfully developed, and this new development of combining advanced ultrasound technology with endoscopy greatly increased the accuracy of the diagnosis of lesions.
