Abstract
An instrument for operating on anatomical tissue includes a barrel having two or more drivers therein which can be manipulated from a proximal end of the barrel. End effectors of each driver are offset from a rotatable shaft by a transverse arm. In an insertion position, the end effectors are confined within the diametrical dimension of the barrel at a distal end thereof. After insertion, the end effectors can be manipulated to extend beyond the diametrical dimension of the barrel to provide a large working span for manipulating tissue or performing other procedures on tissue.
