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.
A surgical stapler comprising a pair of curved jaws of open, non-circular configuration disposed in spaced, generally parallel planes to receive tissue therebetween; a plurality of staples arranged in a non-circular curved pattern on at least one of said jaws; a plurality of staple-forming anvils ar
A surgical stapler comprising a pair of curved jaws of open, non-circular configuration disposed in spaced, generally parallel planes to receive tissue therebetween; a plurality of staples arranged in a non-circular curved pattern on at least one of said jaws; a plurality of staple-forming anvils arranged in a non-circular curved pattern on at least the other of said jaws in opposed relation to said plurality of staples; and means for driving said staples through the tissue and into said opposed anvils to bend tissue penetrating legs of said staples so that said staples are applied to the tissue in a non-circular curved pattern; wherein each of said jaws carries a plurality of staples and staple-forming anvils in staggered relation such that, when said staples are driven through the tissue and into said anvils, crimped tissue penetrating legs of said staples will be aligned with interstices between staple cross-members to assure effective hemostasis.
