Perform targeted surgery. The traditional methods are: 1. By moving the patient to change its position (such as Trendelenburg position) to obtain a better surgical field, this method is inconvenient and may cause more trauma to the patient; 2. By increasing the abdominal wall puncture hole ( Such as 5mm, 10mm trocar), insert some special surgical instruments, and increase the number of hands to open the tissue to achieve the purpose of exposing the surgical field. This method increases abdominal incisions, increases trauma, increases doctor labor, and increases costs; 3. According to doctors Experience, use one end of the surgical suture to fix the tissue to be suspended, and pull the other end of the suture out of the abdominal wall to pull and fix it to achieve suspension. This is the "earth method" commonly used by most surgeons. It is simple and effective, but There is a lack of standardization and special suspension fixing devices, and the effect is quite different; 4. There are other methods introduced by patents, such as the products introduced and converted into products in Bulletin No. CN 105286931 B, which can significantly increase trauma and increase labor force. Under certain circumstances, it can effectively achieve tissue suspension in some surgical scenarios. However, due to the lack of precision due to its operating principle, which is operated from outside the abdomen to the abdomen, tissue suspension cannot be achieved in a considerable number of surgical scenarios.
