ABSTRACT:
A stapler for the anastomosis of blood vessels includes a vessel gripping structure, and an outwardly directed anvil head structure, and a stapler head structure adjustably positioned opposite each other. A first vessel is everted to form a cuff over one head structure, and the cuff is inserted into the end of, or into a fenestration of, a second vessel. The stapler is then activated to staple the two vessels. In a tong-like embodiment with a pair of linear anvils, a pair of sutures at openings between ends of ranks of staples completes the anastomosis. In a cylindrical embodiment with an enlarged head portion, a circular staple cartridge within the head forms a complete closure ring. In both cases the staples do not communicate with the vessel interior. Methods of end-to-end and end-to-side anastomosis are described. In one stapler instrument the vessel gripping structure is a pair of tongs with opposed outwardly-directed anvils on its jaws. The tongs, stapler arms, staple cartridges and staple drivers may be assembled together during surgery allowing greater access to the blood vessel and ease of manipulation. The construction is adapted to suture different tubular tissue structures.
