ABSTRACT:
Anastomosis of hollow viscera is effected interlumenally by a surgical stapler. The stapler includes an ovoid-shaped staple head and an ovoid-shaped anvil which are mounted on the distal ends of an open ring support structure, the major part of which extends between the head and the anvil externally of the viscera. The staple head includes an ovoid-shaped tensor ring, an ovoid-shaped cutting blade and double ovoid-shaped rows of staple drivers. Closing of the instrument's handle grips moves the stapler head toward the anvil whereby the tissue between the head and the anvil is tensioned and stapled and the area within the rows of staples is cut away by the cutting blade.
