Abstract
An endoscopic stitching device including a tool assembly having a pair of juxtaposed jaws; a rotatably supported camming hub defining a groove formed in an inner surface of a central lumen thereof; and a center rod slidably and rotatably disposed within the lumen of the camming hub. The center rod is operatively engaged with the groove formed in the camming hub and engaged with the pair of jaws. The inner groove of the camming hub is configured such that, in at least one position, axial translation of the center rod relative to the camming hub results in rotation of the camming hub and at least one of opening and closing of the pair of jaws. The inner groove of the camming hub is configured such that, in at least one other position, rotation of the canter rod results in rotation of the tool assembly.
