Development Of Endoscopy

With the development of modern science and technology, the endoscope has been completely reformed and uses optical fibers. In 1963, Japan began to produce fiber endoscopes. In 1964, a fiber endoscope biopsy device was successfully developed. This special biopsy forceps for taking biopsies can have suitable pathological materials and is less dangerous. In 1965, fiber colonoscopy was made, expanding the scope of examination for lower gastrointestinal diseases. In 1967, he began to study the magnifying fiber endoscope to observe fine lesions. Fiber optic endoscopes can also be used for in vivo assays, such as measuring internal 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 combining advanced ultrasound technology with endoscope greatly increased the accuracy of lesion diagnosis.
In 1987, Phillipe Mouret first pioneered video endoscopic surgery.
Endoscopy in the modern sense was gradually formed with the invention of fiber optic endoscope. Entering the 1960s, "fiberglass" developed in the United States received widespread attention in various fields. As early as the 1930s, there were optical fibers used in fiber optic endoscopes to transmit light, but due to the high loss rate of light in the transmission process, the optical fiber for transmitting optical signals has not been developed. A fiber optic endoscope is a long, thin, flexible tube with a bundle of light-guiding glass fibers inside and a lens at each end. During the inspection, one end of the tube is inserted into the organ to be inspected inside the human body, and the internal conditions of the organ can be seen from the other end. Endoscopes are usually equipped with a light source, and some are equipped with instruments for surgical treatment, such as lasers. Fiber optics are introduced into the light transmission mechanism, and video lenses become the first choice for image capture. The endoscope that can take pictures at the same time is the "fiberscope" born in 1964. It wasn't until the 1960s that endoscopes had image capture and measurement capabilities. Around 1975, the era of gastric cameras came to an end and was completely replaced by "fiberscopes". Zhang Zhenyuan, a Chinese fiber optics expert, undertook the national and local major scientific and technological research project "Series of optical fiber image beams and large-scale production technology research of industrial endoscopes". The production base of beams and endoscopes.
In 1983, a new type of charge-coupled device (CCD) endoscope was first successfully developed by Welch Ailin Instrument Company in New York State, USA. One end of the CCD endoscope inserted into the body is equipped with a CCD "lens" integrated on a small silicon chip, which is actually a new type of photoelectric image sensor, and its function is similar to that of a TV camera. It can convert the image of the part to be checked into a digitized electrical signal, and the image is transmitted through a metal wire and displayed by an "image monitor" similar to a TV receiver. The application of this technology makes image storage, reproduction, consultation and computer management possible.
In November 2002, the world's first "high-definition endoscopy system" was born, and the concept of endoscopy has undergone great changes. It condenses the most cutting-edge imaging technology, and the image accuracy provided makes it possible to diagnose extremely small lesions. The emergence of modern video endoscopes, electronic endoscopes, and ultrasonic endoscopes has opened up a new era of modern medical endoscopes. Endoscopes have entered the era of treatment and surgery from the era of inspection and diagnosis.
