Final answer:
The term '-scopy' involves the use of an endoscope for visual examination and surgery of internal body structures. Using fiber optic technology, it allows for diagnostics and treatment procedures such as biopsies and arthroscopic surgeries.
Step-by-step explanation:
The term ‘-scopy’ refers to the process of visually examining internal structures of the body using an endoscope. This device is a medical tool that allows doctors to explore the body through various orifices or minor incisions. An endoscope is commonly used to diagnose internal physical problems by transmitting light through a fiber bundle to illuminate internal parts, and reflecting images back to the practitioner. These images may be viewed on an eyepiece or a video screen, which gives the doctor a clear view of hollow organs or body cavities. In addition to visual examination, endoscopes can be outfitted with small surgical instruments enabling procedures such as collecting biopsies, removing growths like polyps, and performing surgeries such as arthroscopic surgery on the knee joint.
Laparoscopy is one example of a procedure using an endoscope, where a camera is inserted through the abdominal wall to inspect for conditions like endometriosis. Similarly, procedures like colonoscopy and flexible sigmoidoscopy employ this technology to examine the lower gastrointestinal tract. The flexibility and versatility of the endoscope, using fiber optic technology to transmit images, make it indispensable in modern medical diagnostics and surgeries.
