functions will vary if the given voltage between the working electrode and target tissues is lower. In this
case, the electric field is lower than the value required for forming plasma, and resistance heat at the
tissues is generated. This model is used when stronger heat effect is required, e.g. for coagulation of blood
vessel or other vessel tissues. According to the probe type, tissue status and expected treatment effect, to
set suitable voltage.

Picture 1
The picture 1 shows the main structures of this device.
Signals are formed in the vibration unit and then output is realized in isolation via control side and power
amplifier. Meanwhile, the detection circuit will inspect the output for sampling and then send feedback to
the CPU control center. CPU will control accurately the output as per the preset power value. Each gear
position has the corresponding power range. Detection unit will monitor in real-time the impedance of the
treatment part to judge the `treatment degree.
Display part can show in real-time the treatment time, impedance change, power output value.
In key processing part, the operator can preset the power output, warning and impedance value and change
the working models.
Treatment handle and probes are used to guide the power to the target tissues.
Sound display can display the treatment status during operation.
