3.2 Working Principles
3.2.1 Principle:
This unit can transmit energy to the electrode part at the far end of treatment probe. Electricity flows
between working electrode and circuit electrode, and only generate local energy field. So this design can
generate controllable energy output and minimal collateral tissue damage. In reverse, mono polar system
only has one working electrode at the far end. Electricity comes from the working electrode, and flows
through human body to reach the electrode plate attached to patient, thus making the energy through
human body and surrounding tissues get much larger.
3.2.2 How it Works:
To transmit the energy to the electric conduction liquid (e.g. normal saline), which is close to or on the
surface of target tissues. The electric conduction liquid forms a thin layer between working electrode and
circuit electrode. The electric conduction liquid, given with enough energy, can transform to a steam layer
(i.e. plasma) containing charged particles with energy. When the high energy charged particles contact
target tissues, it will realize tissue disintegration by molecular dissociation. Compared with the
conventional electrosurgical system, by this kind of working model, the temperature generated at the target
tissues is much lower, thus bringing less collateral damage to the surrounding tissues. While the unit

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.

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.
