When was the first gastroscopy invented?
Kussmaul is generally credited with the first gastroscopy in 1868. Although unrecognised at the time, the illumination problem was solved around 1878 by Thomas Edison, but 25 years elapsed before the incandescent lamp was incorporated into endoscopes.
Who was the one that created the 1st endoscope?
In 1853, Antoine Jean Desormeaux of France developed an instrument specially designed to examine the urinary tract and the bladder. He named it “endoscope,” and it was the first time this term was used in history.
What is an endoscope instrument?
An endoscope is a medical device with a light attached. It is used to look inside a body cavity or organ. The scope is inserted through a natural opening, such as the mouth during a bronchoscopy, or the rectum for a sigmoidoscopy.
How does an endoscope work?
An endoscope is a thin, flexible tube with a light and a tiny camera on the end. The doctor inserts it into the mouth, down the throat, and into the esophagus. The doctor views the images on a screen to look for tumors or other health problems.
Who is the father of endoscopy?
Philipp Bozzini–the father of endoscopy.
When was colonoscopy invented?
William Wolff and Dr. Hiromi Shinya pioneered the development of the colonoscope. Their invention, in 1969 in Japan, was an advance over the barium enema and the flexible sigmoidoscope because it allowed for the visualization and removal of polyps from the entire large intestine.
When were endoscopes first used?
The first effective open-tube endoscope was developed in 1853 by Desormeaux. This instrument was used to examine the urethra and the bladder. In the late 1800’s, other physicians including Kussmaul and Nitze refined the original endoscopic models and began utilizing their new tools in their medical practice.
Who discovered the self illuminated endoscope?
The self-illuminated endoscope was developed at Glasgow Royal Infirmary in Scotland (one of the first hospitals to have mains electricity) in 1894/5 by Dr John Macintyre as part of his specialization in investigation of the larynx.

How is endoscope made?
How is an Endoscope Made? The heart of an endoscope are the fiber optical components made by inserting glass rods into an oven and then melting the rods at 900° Celsius. The melted glass drips down onto a wheel, forming thin strands. The fibers are stretched on another wheel until they are finer than a human hair.
How do endoscopes Bend?
Applying a tension force to one of these tension members causes a distal tip of the flexible endoscope to bend in a first direction, while applying a tension force to the opposite tension member causes the distal tip to bend in an opposite direction.
