ABSTRACT:
A cold plasma coagulator clots blood bleeding from tissue during surgical operation in an effective manner, by applying unipolar cold plasma to the blood. The cold plasma coagulator has a high frequency power supply, gas dynamic block and plasmotron. The power supply has a rectifier, capacitor storage and voltage inverter. The said plasmotron is assembled in a hermetically sealed case and in which resonance inductor and dielectric tube are located coaxially. One end of the dielectric tube is connected to the gas dynamic block, another end is positioned to eject plasma through output nozzle. A needle corona electrode is located along the axis of the dielectric electrode. The coils of the resonance inductor has a low voltage and high voltage section, the low voltage section of resonance coils being connected to output of the voltage inverter. One pin of the high voltage section is isolated and another one is connected to the needle corona electrode.
