According to classification of protective degree, this unit with full-suspension output belongs to Class I Type CF anti-defibrillation ( ) electric apparatus for common medical use.
Its body has protective ability against the overturn of liquid. Its controlling footswitch is soak-proof (IPX7).
This unit generates specific wave and power of high frequency current. It has cutting and coag syncretic function. The needle of electrode goes straight to make cutting, point touch to make pin-coag.
In order to produce high-power high frequency electrotome with high stability, high reliability, high performance and high safety, this unit adopts VMOS high-frequency power elements to constitute half-bridge high-frequency switch power supply and all-bridge ON-OFF high-frequency power amplifier in addition to the tuning balance out return circuit, full isolation of high-frequency transformer and CMOS integrated control. Therefore, it’s function and safety index conform to the IEC60601-1 International Standard and IEC60601-02-02 Part 2: Particular requirements for the safety of high frequency surgical equipment
Efficiency of this unit ≥ 72 %
Efficiency of switch power supply ≥ 85 %
Efficiency of high-frequency power amplifier≥ 75 %
Operation of equipment
Continuous operation with intermittent loading, 10s/30s
Natural cooling, without fan
This unit’s monopolar mode can not only use finger switch to start up the output of the hand-switch pencil but also use footswitch to start up the output of the foot-switch pencil, both of which are independent of each other.
Power can be set by adjusting the knob on the front panel. (Digital code display).
This unit has auto-protection functions against open circuit, short circuit, overpower, and excess current and overvoltage. When the patient plate is not correctly connected or its connecting cable is disconnected, it has the protective function of cutting off the output with the acousto-optic effect alarm.
Its output power be displayed respectively with a group of three digits on LED (nixie tube). When the mode is started up, it is indicated by a yellow light and 500 Hz continuous sound (40~65 dB adjustable). When the patient plate alarm sounds, it is indicated (and the output is cut off) by a red light and 1000 Hz be disconnected sound (65 dB not adjustable).
