What is the typical diameter range for flexible endoscopes?

Flexible endoscopes are designed to navigate various anatomical pathways and provide access to internal organs while minimizing patient discomfort. The typical diameter range for these instruments, which can vary based on the specific type and use, generally falls within 5 to 13 mm. This range allows for effective visualization and intervention in areas such as the gastrointestinal tract, respiratory system, and urinary tract. Endoscopes within this diameter range strike a balance between being slim enough to minimize trauma and being sufficiently robust to incorporate high-quality imaging and operational capabilities.

In contrast, smaller diameters, such as those in the 2 to 5 mm range, might limit functionality and the resolution of imaging, while larger diameters, like 10 to 15 mm, could increase the risk of complications and discomfort during procedures. Therefore, the diameter range of 5 to 13 mm is optimal for a variety of flexible endoscopic applications.
