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.

Abstract: An elbow joint surgical treatment includes transmitting an ultrasonic vibration to a treating portion of an ultrasonic device to excise the treated object region of the synovial membrane, and bringing the treating portion of the ultrasonic device, used in excising the synovial membrane, to come in contact with an osteophyte positioned in one of a coronoid fossa of a humerus, an olecranon fossa of the humerus, a coronoid process of an ulna, and an olecranon. The surgical treatment includes transmitting an ultrasonic vibration to the treating portion in contact with the osteophyte to remove the osteophyte.
