the light that is sent down the tube reflect of the sides making the light 'bend' down the tube and making it use internal reflection. once it gets to the end of the tube inside the patient, the image is reflected back to the person on the outside so they can see inside.

Total internal reflection is used in fiber optics to transmit data - usually as ones and zeroes. This data can represent any type of information - text, voice, images, video, executable programs, etc.
The minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45 degrees is 1.414
X - rays.
It is used in optical fibers. It is also the reason we see a rainbow and why diamonds have their brilliance.

TIR stands for Total Internal Reflection and it can be used for means of communications via internet or broadband. Also, it can be used for different kinds of Surgery.
A panendoscopy can be used in general terms as an endoscope (a flexible, typically fiber optic instrument used for viewing internal organs) used for wide-angle viewing. The more common definition of penendoscopy the use of an endoscope for viewing the bladder. See related link below.
An endoscope is used to view the stomach and esophagus through a procedure called an endoscopy. It is a flexible tube with a light and camera on the end that is inserted through the mouth and into the digestive tract to provide internal images for diagnosis and treatment.
