Difference between flexible and rigid endoscope
What is Rigid Endoscopy?
Rigid vs flexible endoscopy involves the use of a straight, inflexible tube to examine specific areas of the body. This type of endoscope is typically made of metal and is used in procedures where a straight path to the target area is available. Common applications include examining the ear, nose, throat, and certain parts of the urinary and reproductive systems. Rigid endoscopes provide high-quality images due to their stable structure. However, they can be uncomfortable for patients and are not suitable for examining areas that require navigation through curves or bends.
