The invention provides a technical method of negative-pressure wound treatment method used for prevention and treatment of scarring hyperplasia at the surgical suture. Implicit factors of scar hyperplasia are mechanical stress, infection, inflammatory reaction and foreign body reaction of wounds. Among the implicit factors, wound tension plays a key function in the scar formation. Frequently-used scar prevention and treatment methods such as Silicone gel, pressure therapy, hormone injections and the like are poor in curative effect or has side effects. The negative-pressure wound treatment method is a novel prevention and treatment for wounds and scars at the surgical suture. Based on the structure and working principle of the negative-pressure wound treatment, the scarring hyperplasia can be effectively inhibited through closing, fixing and pressing the sutured wounds and playing continuous negative-pressure action on the wounds; at the same time, the main factors leading to the scar formation are intervened.
