The world's first endoscope was created in 1853 by the French doctor Desormeaux. Endoscope is a commonly used medical equipment. It consists of a bendable part, a light source and a set of lenses. When used, the endoscope is introduced into the pre-examined organ, and changes in the relevant parts can be directly visualized.
The earliest endoscopes were used for rectal examinations. The doctor inserted a rigid tube into the patient's anus and observed rectal lesions with the help of the light of a candle. 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.
Bronchoscopy was envisioned in 1897 by a German, G. Kilian, and more than 20 years later it entered the practical stage with the impetus of an American, Joan Chevalier Jackson. Soon after, it was used in routine pulmonary examinations. 1862, the German Small created the esophagoscope. 1903, the American Kelley created the proctoscope, but it did not come into general use until after 1930. 1913, the Swede Jacobs reformed pleuroscopy. 1922, the American Schindler created gastroscopy. 1928, the German Kalk created the laparoscopy method. In 1928, the German Kalk founded the laparoscopy method, and in 1936, the American Scarf carried out ventricular microscopy tests until 1962, when the Germans Gouaux and Freystier founded the ventricular microscopy method. From then on, a whole series of microscopy method was formed.
With the development of modern science and technology, endoscopy after a thorough reform, with optical fiber. 1963, Japan began production of fiber endoscopy, 1964 developed a successful fiber endoscopy biopsy device, the biopsy of the special biopsy forceps can have the right pathology and less dangerous. 1965, fiber colonoscopy was made to expand the scope of examination of the lower gastrointestinal tract. 1967 began to study the scope of examination of the lower digestive tract. In 1967, research began on magnifying fiberoptic endoscopes to view microscopic lesions. Fiberoptic endoscopes can also be used to perform in vivo assays, such as measuring body temperature, pressure, displacement, spectral absorption, and other data.
In 1973, laser technology was applied to the treatment of endoscopy, and gradually become one of the means of transendoscopic treatment of gastrointestinal bleeding. 1981, endoscopic ultrasound technology was successfully developed, this advanced ultrasound technology and endoscopy combined with the new development, greatly increasing the accuracy of the diagnosis of lesions.
Medical endoscopy in different periods have promoted the continuous development of the medical cause. In the future, with the continuous progress of electronic technology and other science and technology, it is believed that its technology will have a broader and deeper development.
The development of medical endoscopy technology has shown its strong vitality today, and it is believed that it will make more brilliant contributions tomorrow.
