Fractional CO2 Laser Machine

The Fractional CO2 Laser Machine is a surgical laser device that emits CO2 laser light at 10.6 micrometers wavelength for two primary uses: fractional mode for ablative skin resurfacing, and impulse mode for incision, excision, ablation, vaporization, and coagulation of soft tissues across multiple surgical specialties including dermatology, plastic surgery, ENT, gynecology, neurosurgery, and dental surgery.

The proposed device uses a 30W CO2 laser at 10.6 μm wavelength with pulse durations of 100-5,000 microseconds, maximum fractional pulse energy of 150 mJ, repetition rate up to 1,000 Hz, and fractional spot patterns delivering up to 289 spots per square centimeter with spot sizes of 100-200 micrometers. It features an LCD touchscreen interface, articulate optical guide arm, and air cooling. The electrical requirement differs from the predicate (100-120V versus 100-240VAC), though the device passed electrical safety and EMC testing.

IEC 60601-1 (medical electrical equipment general safety), IEC 60601-1-2 (electromagnetic compatibility), IEC 60601-2-22 (surgical laser equipment), IEC 60825-1 (laser product safety classification), ISO 10993-5 (cytotoxicity testing), ISO 10993-10 (skin sensitization), and ISO 10993-23 (irritation testing).

The proposed device is substantially equivalent because it shares identical laser type, wavelength, output power, pulse parameters, fractional spot density, scan area, and biocompatibility safety profile with the predicate Ilooda Fraxis CO2 Laser. Although the electrical input specifications differ, safety and EMC testing confirmed the device operates normally under its specified requirements. The inter-beam spacing, calculated from identical microbeam diameter and spot density, should match the predicate device. All critical performance and safety characteristics are identical, demonstrating equivalent safety and effectiveness for the same indications of use.
