leep is the name of a cervical surgery, also known as cervical loop electrosurgery, is one of the surgical methods commonly used in the treatment of gynecological cervical intraepithelial neoplasia, is a minimally invasive surgery, the cervical lesion tissue for excision, to obtain a cure for cervical disease treatment methods. Cervical sleep surgery uses high-frequency radio knife to generate ultra-high-frequency electric waves from the electrode tip, and in the moment of contact with the body’s tissue, the tissue itself generates impedance and absorbs the electric waves to generate high heat, so that the intracellular water forms vapor waves to complete various cutting and hemostasis procedures, and does not affect the pathological examination of the tissue at the edge of the incision. It is mainly used in the treatment of various cervical diseases, and is more effective in the treatment of cervical diseases such as mild, moderate and severe atypical hyperplasia, cervical erosion, cervical polyps and other types of cervical diseases.
