1. An endoscopic stitching device, comprising:

  • a tool assembly including;

    a pair of juxtaposed jaws pivotally associated with one another, each jaw defining a needle receiving recess formed in a tissue contacting surface thereof;

    a drive assembly; and

    a pair of needle engaging blades slidably supported, one each, in a respective jaw, each blade having an advanced position wherein a distal end of the blade engages a suture needle when the suture needle is in the respective jaw to thereby secure the suture needle to the jaw, and a retracted position wherein the distal end of the blade is out of engagement with the suture needle to thereby permit the suture needle to be removed from the jaw, wherein a proximal end of each blade is rotatably connected to the drive assembly; and

    a center rod slidably and rotatably disposed through the drive assembly, a distal end of the center rod being operatively engaged with the pair of jaws,wherein an axial translation of the center rod results in one of an opening and a closing of the pair of jaws; and

    wherein a rotation of the center rod causes the drive assembly to rotate resulting in opposed axial translation of the pair of blades.
