Radiofrequency lipolysis waist surgery is the use of bipolar radiofrequency generated by the thermal effect, so that the cell volume increases, the cell membrane rupture, so as to make the adipose tissue coagulation or liquefaction necrosis, so as to treat fat accumulation. At the same time of treating fat accumulation, heat energy acts on fascia, connective tissue of fat diaphragm and collagen fibers of deep dermis, making skin and soft tissue contraction to produce skin tightening effect. It has the advantages of simple operation, safety, minimally invasive, good treatment effect, quick recovery and patient tolerance. Although the procedure has more advantages compared with traditional liposuction, there are still some surgical risks, such as the larger cavity under the skin is filled with non-coagulable serum-like fluid after the operation, which may form chronic seroma, skin necrosis, skin necrosis of the deep tissues are damaged leading to tissue adhesion, deep unevenness, concavity, local nerve damage, pain pulling, hyperpigmentation, and infection. Or the doctor’s operation technology level is not up to standard, such as the doctor’s operation to move the handle faster, to carry out continuous operation resulting in excessive energy, the use of the instrument is not skilled enough to choose the appropriate parameters for the candidate, etc., resulting in adverse reactions, such as postoperative pain, erythema, hematoma, edema, infection, skin burns, treatment incision scarring, treatment area and the surrounding nerves of one-pass damage, and so on. Therefore, it is recommended that candidates choose a professional medical institution to perform this surgical operation.
