1. Apparatus for assembling staple drivers in a cartridge to be used during surgery comprising,said cartridge being an elongated generally rectangular shape, one of the sides of said rectangle including a channel extend longitudinally along said side;

  • a plurality of pocket openings in said side, said pocket openings being linearly aligned generally parallel with said channel, said pocket openings being one end of a plurality of pockets extending completely through said cartridge from pocket entrances on the opposite side of said cartridge from said pocket openings, said pocket openings having a geometric shape;

    a bracket having a trough configured to receive said cartridge only by linear insertion with said pocket opening facing away from overlying plungers,a guide fixture mounted between said plungers and said cartridge including guide passages converging toward said pocket entrances;

    said passages being formed to receive a plurality of tree mounted staple drivers of a size and geometric shape generally corresponding to the size and geometric shape of said pocket openings;

    said tree being formed with a plurality of branches and with a staple driver on one end of each branch, said staple drivers being linearly aligned;

    said guide passages converging to a size and geometric shape generally corresponding to the size and geometric shape of said staple drivers, whereby the narrowest parts of said guide passages are a snug fit for said staple drivers and thereby said narrowest parts are structurally configured to prevent misalignment of said staple drivers as said staple drivers are separated from the branches of said tree;

    said overlying plungers including blades aligned with said guide passages and pockets mounted on a plate,said plate being mounted to reciprocate with respect to said bracket whereby said blades engage said staple drivers after said staple drivers are separated from said tree and push said staple drivers into said pockets.
