摘要： In accordance with the present disclosure a directionally biased staple is provided for use in all types of surgical staplers having anvil structure against which the staple is formed. The directionally biased staple may be constructed in a wide variety of cross-sectional configurations including rectangular, elliptical, trapezoidal, etc. All of the configurations are distinguished by having a bending region requiring more force to twist or malform the staple than is required to properly form the staple. Preferably, these staples have Moment of Inertia Ratios on the order of between about 1.1 to about 3.0. The staple preferably corresponds in other respects to conventional formed staples, i.e. having at least a pair of leg members interconnected by a crown portion wherein the leg members are formed by direct contact with the anvil. An anvil assembly is also provided for minimizing the malformation of staples.

摘要： An anvil assembly for use with a surgical stapler having a tissue contact surface and a plurality of staple pockets formed in the tissue contact surface. Each of the plurality of staple pockets including first and second staple forming cups, each of the first and second staple forming cups having an outside portion and an inside portion, the inside portion of the first and second staple forming cups being positioned in close relation to each other and the outside portion of the first and second staple forming cups being positioned in spaced relation to each other. Each of the first and second staple forming cups being defined by sidewalls and an elongated base surface, wherein upper portions of the sidewalls intersect the tissue contact surface at a line of intersection, and wherein the line of intersection is curved along a majority of its length between the outside portion and the inside portion of each of the staple forming cups.
