Colon checks can miss spots when the long flexible scope won’t stay steady — steadier control aims for a thorough look and treatment in the same visit.

The useful capability is on-demand steadiness: stay flexible while navigating curves, then hold shape so the tip and tools do not fight the bends while looking or treating.

A permanently stiff tube cannot follow colon curves safely. A permanently floppy tube loops. The hard-to-vary idea is switchable steadiness timed to the task — not a rigid pipe through the whole bowel.

Remember the one idea: miss spots when the scope will not stay steady; aim for steadier control so look and treatment can finish in the same visit.
