The structure of the refrigerant internal circulation cavity is described by taking the first refrigerant internal circulation cavity as an example. The first refrigerant internal circulation cavity comprises a water return inner cavity 5 and a water inlet inner cavity 6, and the water inlet inner cavity 6 is not communicated with the water return inner cavity 5. The water inlet of the water inlet inner cavity 6 is the water inlet of the first refrigerant inner circulation cavity, the water inlet of the first circulation channel is connected to the inside of the water inlet inner cavity 6, the water outlet of the first circulation channel is connected to the inside of the water outlet inner cavity 5, and the water outlet inner cavity 5 is connected to the water outlet of the first refrigerant inner circulation cavity through a pipeline.

Along with the continuous injection of energy, the hemostatic effect is better. Meanwhile, as the current flows between the sub-needles, the blood coagulation zone is linear, has smaller width and small damage to normal tissues, and improves the safety of tumor blood coagulation cutting.
