K180523 is an FDA 510(k) clearance for the INTAI Surgery Navigation System. Classified as Orthopedic Stereotaxic Instrument within the OLO classification (a category covering orthopedic stereotaxic and surgical navigation instruments), Class II - Special Controls.

Submitted by Intai Technology Corporation (Taichung, TW). The FDA issued a Cleared decision on September 20, 2019 after a review of 570 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Orthopedic FDA review panel, regulated under 21 CFR 882.4560 - the FDA orthopedic device regulatory framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Orthopedic submissions.
