Liposuction is the use of negative pressure to suck out excess fat. The key surgical instruments are very similar to enlarged needles. There is a mung bean-sized "eye" when the needle is stuck on the skin, and most of the subcutaneous fat in the second and third layers is evenly sucked out. During the operation, swelling perfusion technique was used to make a certain amount of fat sucked out, and 7-day chestnut skin prick was used to digest visceral fat and remove excess fat in the body. Without causing other negative effects on the body. After the operation, the bean-shaped "needle eye" was carefully stitched, and a large number of oral special protamine before and after the operation could hardly see the traces of the operation.
