Can destroy the heating effect of the high frequency electric knife of pathological tissues, be not to be caused by heating electrode or cutter head, as electric cautery.It is that high frequency electric with high current density gathers together, and directly destroys the tissue that is under contacting a bit with the active electrode tip.When contacting with active electrode or the temperature of adjoining tissue or cell when rising to the protein denaturation in the cell; Just produce blood coagulation, this accurate surgical result is to be decided by the shape of the type of waveform, voltage, electric current, tissue and electrode and size.
For avoiding when electric current leaves patient and returns high frequency electric knife, continuing the tissue heating so that the patient that burns, the patient's pole plate in the single-pole device must have big relatively and the contacted area of patient, so that the passage of Low ESR and low current density to be provided.Some is used for, and the high frequency electric knife electric current of Doctor's office is less, density is lower, can be without patient's pole plate, but the used electric current of most of universal high frequency electric knife is bigger, thereby need use patient's pole plate.
And the isolated output system in ground makes the electric current of high frequency electric knife no longer need and patient, the earth between accessory channel, thereby reduced maybe with the contacted body of ground connection thing by the danger of calcination.And adopt with ground is the system of benchmark, and the danger of burning is bigger than the insulation output system.
2, double pole mode
Bipolar coagulation is that two tips through bipolar forceps provide high-frequency electrical energy to body tissue, makes the blood vessel dehydration between the bipolar forceps two ends and solidifies, and reaches the hemostatic purpose.Its sphere of action is only limited between the tweezers two ends, and the degree of injury of body tissue and coverage are wanted much little more than the one pole mode, is applicable to little blood vessel (diameter < 4mm) and oviducal sealing.So bipolar coagulation is used in the comparatively meticulous operation such as department of cerebral surgery, microsurgery, ENT dept., department of obstetrics and gynecology and hands surgery more.The safety of bipolar coagulation is familiar with by the people gradually, and its scope of application is also enlarging gradually.
At present the operation implementation process in, pencil in use, for monopolar mode; Need to be used with negative plate, its subject matter is that electric current need flow through the significant points of human body, increases certain application risk; In addition, need other adhesion pole plate, use inconvenient.For double pole mode, two tips through bipolar forceps provide high-frequency electrical energy to body tissue, and its effect just reaches the hemostatic purpose, can't play the effect of cutting.
Summary of the invention
