Abstract: In a plasma treatment system, a temperature detection section detecting a temperature of a perfusion layer of an electrically conductive solution is fixed to a treatment portion, and is located at a position to be immersed in the perfusion layer when a first electrode portion and a second electrode portion are immersed in the perfusion layer. In the plasma treatment system, a control section controls an adjustment of a temperature in a temperature adjustment unit and controls a supply volume and a suction volume of the electrically conductive solution on the basis of a detection result in the temperature detection section so that the temperature of the perfusion layer is within a target temperature range.

Abstract: A plasma treatment system includes a spout, a suction hole, a first electrode and a second electrode, an impedance acquisition unit, a liquid volume adjustment unit, and a first control unit. The first electrode and a second electrode are configured to generate plasma to treat a living tissue by the application of a voltage. The impedance acquisition unit acquires impedance between the first electrode and the second electrode. The liquid volume adjustment unit adjusts the supply volume or suction volume of the electrically conductive solution. The first control unit controls the liquid volume adjustment unit to increase or decrease the supply volume or suction volume of the electrically conductive solution based on the impedance.
