ENDOSCOPY Endoscopy, is the  examination of internal  body cavities using a  specialized medical  instrument called an  endoscope.  Physicians use  endoscopy to diagnose,  monitor, and surgically  treat various medical  problems.

An endoscope is a slender,  flexible tube equipped with  lenses and a light  source.  Illumination is done by the  help of a number of optical  fibres. Reflected light rays are  collected by CCD( Charge  coupled device) and electrical  signals are produced, which  are fed to the video monitor to  get image. Thorough one channel of  endoscope water and air is  conducted to wash and dry  the surgical site. ENDOSCOPY

The endoscope also has a  channel through which surgeons  can manipulate tiny instruments,  such as forceps, surgical  scissors, and suction devices. A variety of instruments can be  fitted to the endoscope for  different purposes. ENDOSCOPY

A surgeon introduces the endoscope  into the body either through a body  opening, such as the mouth or the  anus, or through a small incision in the  skin.

ENDOSCOPY Depending on the body part, each type of endoscopy  has its own special term, such as  laparoscopy (abdomen, uterus, fallopian tube),  laryngoscopy (vocal cords),  bronchoscopy (lungs),  colonoscopy (colon),  arthroscopy (joint) and  Gastroscopy (Stomach).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
