Radiofrequency lipolysis back surgery is the introduction of the principle of radiofrequency work into the fat suction surgery, the use of controlled radiofrequency energy to ablate the fat tissue, contraction of fat fibers compartment and elastic fibers in the abdominal tissues, so as to achieve the efficacy of tightening the skin soft tissue. In addition, the procedure also uses radiofrequency energy to shrink the soft tissues by 40%-60%, reducing fat while achieving skin tightening, which is widely loved by patients. However, as a surgical procedure, radiofrequency lipolysis thin back surgery still exists a certain degree of surgical risk, specifically including the following aspects: 1, the skin surface temperature caused by the machine parameters are not set reasonably high, resulting in skin burns, infections, as well as the treatment area, the surrounding nerves of a one-off damage; 2, postoperative subcutaneous larger cavities are full of non-coagulable serum-like liquid, which may lead to the formation of chronic seroma; 3, Doctor unskilled operation, radio frequency treatment, moving the handle faster and continuous operation can lead to excessive energy, resulting in tissue damage; 4, deep tissue over-freezing or skin freezing injury resulting in tissue adhesion, deep unevenness, depression, local nerve damage, pain pulling, hyperpigmentation, and so on. In addition, after lipolysis, some of them will be hardened, and there is still a numbness in the operated area, which is mostly normal, and it usually takes 3-6 months to fully recover.
