The Uscope uses as modified working channel that allows full endoscopic spine surgery with standard instruments (conventional, durable) instead of specialized ones (expensive, fragile, longer, difficult to maneuver).
There are several advantages with modified FESS (Uscope) such as the capability of using large or curved standard surgical instruments, easier instrument handling, a more acceptable learning curve, and a reasonable cost. Modified FESS seems to be an effective alternative compared to a conventional full endoscopic spine surgery. With further refinement of the system, the modified FESS might become the next generation.
