1. Inject expansion liquid, with the injection amount of 2000-2500ml. Each part: generally, there are two needles, the upper abdomen can choose both sides of the umbilicus, and the lower abdomen can choose both sides of the umbilicus, and the distance is less than the length of the suction needle; For young women with less fat deposition, the needle insertion site can be selected in hidden parts such as pubic mound.

2. Attraction is carried out by one person or two people at the same time. The suction tunnel is fan-shaped and sucks layer by layer from deep to shallow. When sucking, the "feeling" hand should be flat or pinched on the skin to sense the level of sucking; Umbilical suction should be thorough, and no limitations can be left, but it is difficult to suck, and there is often slight pain. Suction should be gentle so as not to puncture the skin.

3. There is mild pain when sucking the surgical scar. Suction needle should be suctioned through subcutaneous scar tissue, and no fat can be left on both sides to avoid the formation of strip masses after operation; You can suck more fat under the costal arch to show the shape of the costal arch, and the triangular depression under the costal arch should be shaped so that the suction needle does not directly contact the costal (cartilage) membrane. Patients with secondary abdominal liposuction have many subcutaneous adhesions, and the suction operation is difficult. The operator should be patient and meticulous. Electronic suction or ultrasonic liposuction can reduce the suction resistance. Because of supine position and local swelling, deformity is not easy to judge. In order to achieve better results, it is necessary to refer to preoperative photos and marks to accurately suck them out.

4. After suction, squeeze the suction part to discharge the residual swelling fluid and blood; Cover the dressing, apply pressure and wear elastic clothes.
