#### H. Performance Information

The Sonic Surgeon 310L, Sonic Surgeon 600L and Sonic Surgeon 800L have been manufactured and tested to meet the safety requirements of several IEC standards. The Sonic Surgeon 310L. Sonic Surgeon 600L and Sonic Surgeon 800L comply with IEC 60601-1 Medical electrical equipment - Part 1: General requirements for safety and IEC 60601-1-2:2007, Medical electrical equipment - Part 1: General requirements for safety - Collateral standard: Electromagnetic compatibility - Requirements and tests.

#### l. Conclusion:

The performance tests and evidence demonstrate that Sonic Surgeon 310L, Sonic Surgeon 600L and Sonic Surgeon 800L function in a substantially equivalent manner to the predicate device.

In terms of output power, Sonic Surgeon 310L, Sonic Surgeon 600L and Sonic Surgeon 800L are substantially equivalent to the predicate device UBS ultrasonic bone surgery and UDD ultrasonic debridement device (K080220). The maximum output power of Sonic Surgeon 800L is 70~90W and that of UBS ultrasonic bone surgery and UDD ultrasonic debridement device (K080220)' is 90W. In terms of light power, the capacity of the device's LED light is demonstrated in 'Biocompatibility' section and an LED report was attached as evidence.

Because our proposed device has the same intended use, the same sterilization method, same materials used, same electrical input power, same frequency, and same power output as predicate devices, as well as similarity of product configuration and administration, it can be concluded the Sonic Surgeon 310L, Sonic Surgeon 600L and Sonic Surgeon 800L are substantially equivalent to the identified predicate devices.
