Endoscopic Instrument Optical fiber

Endoscopy with the optical fiber endoscope invention and gradually formed

    With the development of modern science and technology, endoscopy through a thorough reform, the use of optical fiber. In 1963, Japan began to produce fiber endoscopy, 1964 developed a successful fiber optic endoscopic biopsy device, this biopsy of the biopsy forceps can have a suitable pathology and the risk of small. In 1965, fiber colonoscopy was made to expand the scope of examination for lower gastrointestinal diseases. 1967 began to study the amplification of fiber endoscopy to observe the micro-lesions. Fiber endoscopes can also be used for in vivo testing, such as measuring body temperature, pressure, displacement, spectral absorption, and other data. In 1973, laser technology used in endoscopic treatment, and gradually become endoscopic treatment of gastrointestinal bleeding one of the means. In 1981, endoscopic ultrasound technology successfully developed, this advanced ultrasound technology and endoscopy combined with the new development, greatly increasing the accuracy of the diagnosis of the disease.

    In 1987, Phillipe Mouret first created a TV endoscopic surgery. The endoscopic examination of modern significance is gradually formed with the invention of optical fiber endoscopes. Into the 20th century, 60 years, developed in the United States, "glass fiber" by various areas of widespread concern. As early as the 20th century, 30 years, there have been used for optical fiber endoscopic light transmission fiber, but because of the loss of light in the transmission process is too high, the optical signal transmission optical fiber has not made progress. Optical fiber endoscope is a slender and soft tube, the tube has a beam of light guide glass fiber, both ends are equipped with a lens. Check the end of the tube into the body to be found inside the organ, from the other end can see the internal organs of the situation. Endoscopes are usually accompanied by lighting, and some are equipped with surgical instruments, such as lasers. In the optical transmission mechanism introduced in the fiber, video camera image capture as the first choice. The endoscope that was able to take pictures at the same time was the "fiber endoscope" that was born in 1964. By the 1960s, endoscopes had image capture and measurement capabilities. In 1975 or so, the era of the stomach camera came to an end, completely replaced by "fiber endoscopy". China's fiber optic expert Zhang Zhenyuan commitment to the national local major scientific and technological projects "series of optical fiber transmission beam and industrial endoscopic large-scale production technology research", the technology reached the leading domestic and world advanced level, and the establishment of the only series can produce mass production Beam and endoscopic production base.

    In 1983, a new type of charge-coupled device (CCD) endoscope was first developed by New York-based Welch-Ailin Instruments. The CCD endoscope is inserted into one end of the body and is fitted with a CCD "lens" integrated in a small piece of silicon. It is actually a new type of photoelectric image sensor with a similar function to a television camera. It converts the image of the part to be detected into a digitized electrical signal, which is transmitted through the metal wire and is displayed by an "image monitor" like a television receiver. The application of this technology makes it possible for image storage, reproduction, consultation and computer management.
