Abstract: The purpose of modern hernia surgery is to repair the defects of abdominal wall and restore abdominal wall function, eliminate all complications, and improve the quality of life in patients ultimately. A kind of “PERFECT” patch should not only has ideal tensile strength, but also has the optimal biocompatibility. Although many kinds of patches are beneficial to hernia patients, there is still no universal patch that can be used at any time, in any patient, in any kind of hernia and by any surgical technique. In the past 10 years, biological patch has been used in the field of abdominal wall hernia and achieved certain curative effects, but there are also some problems which are worthy of summary and reflection. In the future, a series of functional biomaterials represented by “tissue-induced biomaterials” may be the closest patch to “IDEALIZATION” in our time.
