Zusammenfassung:A buttress assembly (322) for use with a surgical stapled site has a buttress and an adhesive (320) on one side of the buttress. The buttress itself has a multi-layer construction with a mesh layer (326) on one side, a film layer (334) on the other side, and an adhesive film layer (332) in between the mesh layer and film layer. The mesh layer (326) is a knit material with multiple openings that provide space for and promote tissue ingrowth with the buttress. As such the buttress is oriented in use so that the mesh layer faces and contact the tissue at the surgically stapled site. Opposite to the mesh layer, the film layer faces away from the tissue at the surgically stapled site and acts as an adhesion barrier. 本发明涉及一种与外科缝合部位一起使用的支撑物组件(322),所述支撑物组件具有支撑物和在所述支撑物的一侧上的粘合剂(320)。所述支撑物本身具有多层构造,所述多层构造具有在一侧上的网格层(326),在另一侧上的膜层(334),以及在所述网格层和所述膜层之间的粘合剂膜层(332)。所述网格层(326)为具有多个开口的针织材料,所述多个开口为所述支撑物提供空间并且用所述支撑物促进组织向内生长。因此,所述支撑物在使用中被取向成使得所述网格层面向并接触所述外科缝合部位处的组织。与所述网格层相反,所述膜层背朝所述外科缝合部位处的组织并用作粘附屏障。
