(2) Cut the skin and subcutaneous tissue according to the designed incision, separate the subcutaneous fat layer slightly with scissors, hold the handle of the suction head with the right hand and insert the suction head into the suction position, then start the electric suction device to make the negative pressure reach 66.5 ~ 93.1kpa (500 ~ 700 mmhg), and perform sawing and suction according to the marked range. When operating, the side hole of the suction head generally faces the deep surface or side, and the left hand touches the skin surface of the suction part or lifts the suction tube together with subcutaneous fat to grasp the operating depth and suction amount. According to expert Bai Shucheng, at this time, it can be seen that yellowish adipose tissue is sucked out through a transparent connecting tube during abdominal liposuction surgery. With the development of abdominal liposuction, the extract can gradually turn red with a small amount of blood until it is close to purple in whole blood samples. At this time, the suction should be stopped and the suction head should be pulled out without negative pressure. In this way, tunnel suction is performed radially around the incision. If the suction range is large, several small incisions can be used, so that the tunnels pumped by each incision cross and the remaining subcutaneous tissue is honeycomb, which can not only reduce bleeding, but also reduce the unevenness of the skin surface after abdominal liposuction.
(3) Drainage: After the abdominal liposuction operation is completed, one or several silicone tubes are placed through the incision according to the suction area, so as to be connected with the negative pressure drainage bottle for postoperative drainage.
(4) Bandage: Cover the incision with sterile gauze, evenly place sterile cotton pads or sponges on the surface of the whole suction part, and cover it with a special elastic pressure suit or elastic sleeve to ensure the effect of abdominal liposuction.
