The four embodiments described above can be seen: because the volume of the D-shaped ceramic column is larger than that of the cylindrical ceramic column, more radio-frequency electrode discharge ends can be arranged aiming at the design of the D-shaped ceramic column, and then the cutting capability of the corresponding electrode cutting device is stronger, so that the D-shaped ceramic column can be used for cutting soft tissue structures with higher hardness. Because the volume of the cylindrical ceramic column is smaller than that of the D-shaped ceramic column, fewer radio-frequency electrode discharge ends can be arranged aiming at the design of the cylindrical ceramic column, and the corresponding electrode cutting device is weaker in cutting capacity and can be used for soft tissue cutting with lower hardness. Meanwhile, under the condition that the effective working area of the radio-frequency electrode is set, the discharge capacity of the radio-frequency electrode is different by changing the radio-frequency signal emitted by the radio-frequency source, and the same cutting device is adopted to complete the ablation and cutting of soft tissues with different hardness.
