K141594 is an FDA 510(k) clearance for the Unimicro Trocar Kit, models: Auto-Locking Trocar, Hasson Trocar, Bladeless Tr.... Classified as Laparoscope, General & Plastic Surgery (product code GCJ), Class II - Special Controls.

Submitted by Unimicro Medical Systems (Shenzhen) Co., Ltd. (Shenzhen, Guangdong, CN). The FDA issued a Cleared decision on August 10, 2015 after a review of 423 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the General & Plastic Surgery FDA review panel, regulated under 21 CFR 876.1500 - the FDA general and plastic surgery device 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 General & Plastic Surgery submissions.
