An endoscopy procedure involves inserting a long, flexible tube (endoscope) down the throat and into the esophagus. A tiny camera on the end of the endoscope lets the doctor examine the esophagus, stomach and the beginning of the small intestine (duodenum).

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 steer?

During endoscopy, the physician holds the proximal end of the flexible endoscope that contains the control wheels, and uses this to steer the tip. The tip contains a camera and a light source that allow the physician to investigate the gastrointestinal (GI) tract via his/her monitor. Fig. 1.

Who invented endoscopy?

What is endoscope in light?

What are the parts of an endoscope?

The endoscope has three parts: the control section, the insertion section, and the connector section. The angulation knob on the control section is connected to the tip of the endoscope by a series of wires.

How does light travel through an endoscope?

In conclusion, the light wave, which reflects from the passageways of the human body and enters the optical fibres in the endoscope, travels through the optical fibres with total internal reflection. As a result, the light exits the optical fibres in the same way it entered them (with the same angle).

Who invented endoscopes?

When was the first endoscope first created?

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.

What is inside an endoscope?

Endoscopy consist of a control head and a flexible shaft with a manoeuvrable tip. The head is connected to a light source via an ‘umbilical’ cord, through which pass other tubes transmitting air, water and suction, etc. The suction channel is used for the passage of. diagnostic tools (e.g. biopsy forceps) and.
