Endoscopic Instrument flexion

Endoscope is a commonly used medical device. It consists of a curved part, a light source and a set of lenses. Through the human body's natural orifice, or through a small incision made into the human body. When using, the endoscope is imported into the pre-examined organ, which can directly peer into the changes of the site. The quality of image directly affects the use of endoscope, and also indicates the development level of endoscopic technology. The earliest endoscopes were used for rectal examination. The doctor inserted a hard tube into the patient's anus and looked at the rectal lesions with the light of the candle. The diagnostic information available to this method is limited, the patient is not only very painful, but also because the instrument is very hard, the danger of perforation is very large. Despite these shortcomings, endoscopy has continued to be applied and developed, and has gradually been designed with many different USES and different types of instruments.

Endoscope, through the body's natural orifice, or a small incision made by surgery into the body. Endoscope is a commonly used medical instrument. Consists of a flexible part, a light source, and a set of lenses. When using, the endoscope is imported into the pre-examined organ, which can directly peer into the changes of the site. The quality of image directly affects the use of endoscope, and also indicates the development level of endoscopic technology.

History of endoscopic medical application

The world's first endoscope was created in 1853 by the French doctor desormio. Endoscope is a commonly used medical instrument. It consists of the head, bending, insertion, operation and guiding light. When using, the endoscope is connected to the corresponding cold light source, then the insertion department is imported into the pre-inspected organ, and the control operation department can directly peer into the lesion of the relevant part.

The earliest endoscopes were used for rectal examination. The doctor inserted a hard tube into the patient's anus and looked at the rectal lesions with the light of the candle. The diagnostic data that this method can obtain is limited, the patient is not only very painful, and because the instrument is very hard, the danger that causes perforation is very big. Despite these shortcomings, endoscopy has continued to be applied and developed, and has gradually been designed with many different USES and different types of instruments.

In 1855, the Spaniard, carhsa, invented the laryngoscope. German Hyman von helmoz invented the goggles in 1861.

In 1878, Edison invented the light bulb, especially after the invention of the miniature bulb, which made the endoscope a great development, and the temporary arrangement of the surgical procedures can be very accurate.

In 1878, German urologist liam neitz created a cystoscope and used it to examine certain lesions in the bladder.

In 1897, the German golian envisions a bronchoscope.

In 1862, the German, smalls, created the esophagus.

In 1903, American kelly invented the colonoscopy, but it was not widely used until 1930.

In 1913, the Swede jacobs reformed the pleural examination.

In 1922, American hindler founded gastroscopy.

In 1928, German Carl keck created the gastroscopy.
