Abstract
A surgical stapler for applying multiple rows of surgical staples to biological tissue includes a pair of opposed jaws adapted to receive tissue therebetween, a plurality of surgical staples and staple-forming anvils carried by each jaw in alignment with the staples and staple-forming anvils carried by the other jaw, and a mechanism for driving the tissue penetrating legs of the staples through the biological tissue and bending the legs against opposed anvils on the opposite side of the tissue to produce rows of finished surgical staples on both sides of the tissue being ligated. The staples and anvils in each of the jaws are arranged in spaced, parallel rows, with each row of staples being adjacent a row of anvils and adjacent rows of staples and anvils being either longitudinally staggered or aligned. Further, the staples and anvils are carried either alone or in combination in a pair of cartridges held by the opposed jaws, which are either linear or curved depending on the procedure to be performed with the surgical stapler.
