2. ENDOSNCOPY PRINCIPLE
• Endoscopy minimally invasive
diagnostic medical procedure
used to evaluate interior surface
of an organ.
• Endoscope may have rigid or
flexible tube inserted into body.
It has ability to looking inside the
body using a variety of very
small cameras attached to
flexible or rigid tube. It facilitates
direct viewing the interior of an
organ is often very helpful in
determining the cause of a
problem.
3. ENDOSCOPY PRINCIPLE(Contd…)
• An endoscope is a flexible
tube equipped with lenses and
a light source. Illumination is
done by the help of a number
of optical fibers.
• Video endoscopy performed
by attaching in microchip
camera at the insertion
tube, setup image is viewed
on a video monitor.
6. Distal tip of insertion tube
• Light Guide lens(BB)
It has light transmission component for
proper imaging. The light enters the
scope, usually at the light guide
connector, through the light guide prong.
The diseased part of the patient body is
illuminated by light shining in.
• Image Guide lens(AA)
Imaging is the primary function of the
endoscope. An image is captured here
though the optical fibre and transferred to
the image transmission device directly
behind the lens system.
7. Distal tip of insertion tube(contd…)
• BIOPSY CHANNEL
It is used for suction of sample
of tissue. May be needed to
remove or may for diagnostic
purposes.
