Hi friends!!!
In our previous blog we have discussed about Ultrasound. Please check out for the link below.
Today we are going to discuss about Endoscope machine.
Endoscopy is a non-surgical procedure done to visually examine the inside of the body. Endoscope is a important diagnostic equipment used to perform endoscopy procedure. Therefore it is important for every healthcare professional to know in detail about endoscope.
Let’s get into the topic.
WHAT IS
ENDOSCOPE?
Endoscope is a long, thin, flexible instrument with a camera and light attached at one end which is used to look deep into the body. Endoscope can be put into the body through the mouth and down the throat or through the bottom.

WHAT IS THE
TECHNOLOGY USED?
Endoscope uses fiber optics, which transmits the light. In this technique fiber optics light is transmitted through a flexible fiber of glass known as optical fiber.
The optical fiber allows for light to travel through curved paths, which makes one of the best systems to view spaces that would normally be difficult to reach. Here, total internal reflection makes it possible for light to travel along the fibers with the light rays hitting the fiber walls at an angle (minimum angle of 82 degree).
WHAT ARE THE TYPES OF ENDOSCOPE?
Gastroscope: Used to view mouth to duodenum, upper part of the body.
Colonoscope: Used to view colon and large intestine.
Proctoscope: Used to view up to rectum, not colon.
Duodenoscope: Used to view liver biliary tree, gall bladder, pancreatic duct.
Bronchoscope: Used to view trachea and lungs.
Paediatric Scope: Specially designed for pediatrics.
Sigmoidoscope: Used to view sigma.
WHAT ARE THE PARTS OF ENDOSCOPE?
Light guide connector: It is connected to the source of illumination (light).
Light guide cable: It connects light guide connector to the scope's control section.
Control section: It carries angulation control operations to allow the operator to manage the scope's performance. It also includes other functions like suction and watering.
Insertion tube: It is the part of the scope which is inserted into the patient's body and it is highly contaminated during the procedure.
Bending Section: It is the vertebrae of the endoscope which enables the endoscope to move vertically and horizontally.
Distal End: It is the tip of the endoscope.
WHAT IS INSERTION
TUBE?
The insertion tube in endoscope consists of the following parts,
1. A channel for suction/instrument
channel.
2. A nozzle for cleaning air and
water feed.
3. A tube for forward water jet.
4. A delicate glass fibers for
bringing light from the light source to the distal end of the endoscope.
5. A fine electrical wire connecting
the CCD image sensor at the tip of the endoscope to the video processor.
6. Insertion tube also consists of
angulation control wires.
All these
tubes bundled together called as insertion tube, it ends at the distal end (Tip) of
the endoscope. The Tip of the endoscope looks like the following.

Now I hope you have
acquired some knowledge about Endoscope machine. We will discuss about topics
related to Biomedical Engineering, Medical Devices, Healthcare in our next
blog.
