What is the uses and function of endoscope?
Endoscopy is a nonsurgical procedure used to examine a person’s digestive tract. Using an endoscope, a flexible tube with a light and camera attached to it, your doctor can view pictures of your digestive tract on a color TV monitor.
What is optical endoscopy?
Endoscopy is a medical procedure that incorporates a fiber optic light and a miniscule camera. The camera inside the endoscopic device projects the image on a screen that the physician can view while performing the procedure.
What is the principle of endoscopy?
The total internal reflection principle of optics is used in endoscopy.
Which waves are used in endoscopy?
Conventional endoscopy observes reflected visible light (400–700 nm) from the mucosal surface. However, the light spectrum extends to shorter wavelengths in the ultraviolet (UV) and longer wavelengths in the near-infrared (NIR) that also can be used for endoscopic imaging (Figure 2).
Which lens is used in endoscopy?
Four-mm rod-lens endoscopes provide full-screen, high-quality images in contrast to the smaller, inferior quality images provided by 3-mm rod-lens endoscopes. The basic endoscopes used by the authors are 4-mm rod-lens endoscopes with 0-, 30-, or 70-degree lenses.
Who needs endoscopy?
Your gastroenterologist may recommend that you get an endoscopy if you are dealing with: Unexplained abdominal pain. Persistent bowel changes (diarrhea; constipation) Chronic heartburn or chest pain.
What is Optical Biopsy?
‘Optical biopsy’ is a novel method that uses spectroscopy at selected wavelengths to diagnose disease such as cancer and atherosclerosis without removing tissue from the body, offering a new armamentarium.
What is fiberoptic endoscopy?
It is the official position of the American Speech-Language Hearing Association that fiberoptic endoscopy is an imaging procedure that may be utilized by speech- language pathologists to evaluate swallowing function. Fiberoptic endoscopy may also be utilized as a therapeutic aid and biofeedback tool during the course of swallowing treatment.
What is Fiberoptic Endoscopic Evaluation?
A fiberoptic endoscopic evaluation of swallowing (FEES) test is a procedure used to assess how well you swallow. During the procedure, a speech-language pathologist (SLP) or an ear, nose and throat doctor (ENT or otolaryngologist) passes a thin, flexible instrument, called a laryngoscope, through your nose.
What is a fiber optic scope used for?
In telecommunications, fiber optic technology has virtually replaced copper wire in long-distance telephone lines, and it is used to link computers within local area networks. Fiber optics is also the basis of the fiberscopes used in examining internal parts of the body ( endoscopy) or inspecting the interiors of manufactured structural products .
Are fiber optics secure?
To Summarize: Fiber Optic cable transmits a more secure signal, with greater clarity. Fiber transmits more information at higher speeds and over longer distances. The advantage of working with fiber is that it is less bulky. The Fiber Cables do not corrode and are less susceptible to damage. Fiber Optics are almost always the better choice.
