Abstract: 【Abstract】 Vacuum sealing drainage technique since the fifties of the last century is proposed. Through continuous improvement in the late 1980s began in the clinic for the treatment of chronic com?plex wound VSD through soft tissue mechanical and biological effects and can stimulate angiogenesis, im?prove blood circulation，promote the continued growth of the cells and granulation tissue, accelerate wound healing significantly. It has been widely used in the treatment of limb trauma, skin and soft tissue defect，osteofascial compartment syndrome and play an important role. Although Vacuum sealing drain?age technology is widely used in the field of surgery, there are few studies on its mechanism. This article will summarize the related mechanism and clinical application of Vacuum sealing drainage technology, and provide the basis for the clinical application of Vacuum sealing drainage technology.
