    • A buttress for use with circular surgical staplers that does not require adhesive to securely fasten the buttress to the stapler. Following cutting and stapling by the circular stapler, the buttress has an adaptive opening through its central region with a diameter smaller than the outer diameter of the stapler anvil. Because of relief features built into the buttress, the stapler anvil may be pulled through the buttress material without causing permanent alteration ot the buttress. These relief features may be provided regardless of whether the buttress is made of inelastic or elastic materials. The buttress is generally circular in shape with an outer diameter sized to coincide with the outer diameter of the stapler body staple compression surface and the outer diameter of the anvil compression surface of a circular stapler with which it is used. Prior to surgical use, the buttress is attached to the stapler with disruptable portions extending from outer perimetal areas of the buttress.
    • 一种与圆形手术吻合器一起使用的支撑件,不需要粘合剂将支柱牢固地固定到吻合器上。 在通过圆形订书机进行切割和装订之后,支撑件通过其中心区域具有直径小于订书机砧座的外径的自适应开口。 由于支撑件内置有浮雕功能,订书机砧座可能会被拉过支撑材料,而不会导致支柱的永久性变形。 可以提供这些浮雕特征,而不管支撑件是由非弹性或弹性材料制成的。 支撑件通常为圆形,外径的尺寸与钉子主体钉紧压缩表面的外径和使用它的圆形缝合器的砧座压缩表面的外径重合。 在手术使用之前,支撑件被连接到订书机,具有从支撑物的外周缘区延伸的可破坏的部分。
