Attributes such as bending life, insertion tube abrasion resistance, and sealing (fluid ingress protection) determine durability in complex anatomical cavities and infection control.

Optical performance directly impacts diagnosis and surgical quality. Indicators such as resolution, Field of View (FOV), Depth of Field (DoF), distortion control, and color reproduction determine whether a surgeon can clearly identify lesions.

Finished product inspection is a rigid requirement for regulatory compliance and market access.
