An instrument for operating on anatomical tissue includes a barrel having two or more driver 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.
[ What is claimed is:] [1.]1. A method of effecting a surgical procedure on anatomical tissue, said method comprising the steps of:introducing first and second connecting members coupled to a distal end of a barrel of an endoscopic device into an area proximate the anatomical tissue, said barrel hav
[ What is claimed is:] [1.]1. A method of effecting a surgical procedure on anatomical tissue, said method comprising the steps of:introducing first and second connecting members coupled to a distal end of a barrel of an endoscopic device into an area proximate the anatomical tissue, said barrel having a handle coupled to a proximal end of said barrel, said first connecting member including a first end effector extending therefrom, said first end effector having at least two relatively movable jaw members operable by said handle, said second connecting member having a second end effector extending therefrom, said second end effector having at least two relatively movable jaw members operable by said handle;rotating said first connecting member about a first axis lying within said barrel from a first position within a diametrical dimension of said barrel into a second position in which at least an extending portion of said first end effector extends beyond the diametrical dimension of said barrel, said first end effector being offset from said first axis, whereby the movable jaw members, when closed, move out of the diametrical dimension of the barrel by the rotating alone; andmanipulating said handle to operate said movable jaw members of said first and said second end effectors in order to move the first and second end effectors between a closed position and an open position whether the first end effector is contained entirely within the diametrical dimension of said barrel or the extending portion extends beyond the diametrical dimension of said barrel.
