At present, liposuction is a safe, effective and rapid weight loss technology, which can achieve the effect of rapid weight loss by directly sucking out excess fat in the tissue layer. When liposuction is used to lose weight, a small incision will be made on the skin surface to facilitate the insertion of liposuction catheter, and then the excess fat will be sucked out from the depth of the tissue by using the pressure difference between the inside and outside of the catheter, so that the fat will be sucked out.
