LEEP (Loop Electrosurgical Excision Procedure) knife is the most advanced means for treating cervical diseases in China at present. The principle is that ultra-high frequency current is introduced into the electrode, and the current generates a large amount of heat at the moment of contacting human tissues, so that cells are broken and vaporized, thereby separating the tissues and realizing the electrotome function; in addition, the heat energy can raise the temperature of the tissue or the cells, so that the cells are dehydrated and dried and the protein is denatured, and the electric coagulation function is realized. The technique can rapidly and accurately cut off pathological tissues, the incision is automatically coagulated, the bleeding is very little, the operation time is short, the injury is small, and the technique is an excellent choice for treating cervical diseases.
During the operation of the LEEP knife, a great deal of smoke is generated, the operation vision is affected, the health of operators is also endangered, and although the operation system is provided with a device for absorbing the smoke, the harmful smoke cannot be completely absorbed; in addition, since the cutting is achieved by using heat energy, thermal burn is inevitably generated to human tissues, and if the surgical experience of the operator is insufficient, carbonization of the surgical wound surface is highly likely to be caused, and the later recovery of the patient is affected.

The basic principle of a plasma surgical system is that plasma energy flows between the working electrode and the return electrode, forming a highly concentrated plasma vapor sheath around the electrodes by saline conduction. The plasma sheath layer is composed of a large number of charged particles, the charged particles generate enough energy and have strong oxidizing property after being accelerated by an electric field, molecular bonds forming target tissue cells are broken at a low temperature (40-70 ℃), so that tissues are rapidly decomposed into molecules and atoms with low molecular weight, and a real-time and efficient tissue cutting and ablating effect is formed at a lower temperature.
