Electric cutting and electric coagulation

　　Electric knife cutting: high density high frequency current on the surface of local tissue centralized heating, make the organization of the rapid expansion of ingredients burst and separate, this operation electrode thin, and the smaller the organization contact area, the more conducive to cutting, electric cutting and mechanical cutting is completely different, it does not need to exert force

　　Electric knife coagulation: high frequency low power, low current density of hemorrhage and damp heat, causes the liquid ingredients (mainly) moisture volatilize, drying, solidification, closed vessels, and did not reach the level of organization burst, so smaller clotting power, or increase the surface contact between the electrode and the bleeding organization operation and make the current density drop (e.g., using electrode side touch), ensure that only coagulation without cutting.
