Anvil for surgical staplers

摘要

An anvil for use in surgical fastener applying apparatus includes an indentation extending lengthwise along at least one of the side walls to provide increased resistance to bending and to permit the application of longer rows of fasteners. An added feature is the deflection preventing member which projects laterally from the side of the anvil and which engages and abuts a corresponding notch in the apparatus for preventing flexure of the anvil when the fastener is closed onto body tissue.
