<p>A stapler for the anastomosis of blood vessels includes a pair of tongs (6) with opposed outwardly-directed anvils (10) on its jaws. Stapler arms (20, 22) carrying stapler head structures (24) are adjustably positioned opposite the anvils (10) and staple drivers (42, 44) having operating handles (41, 43) are provided to drive the staples. The tongs (6), stapler arms (20, 22), and staple cartridges are adapted to be assembled to the staple drivers (41, 42, 43, 44) at a pivot (15) during surgery allowing greater access to the blood vessel (B) (see Fig. 3) which is everted to form a cuff over the tongs (6). A stapler having a cylindrical configuration with an enlarged head portion (118) (see Fig. 8) over which a cuff is everted is also described. A circular staple cartridge (140) (Fig. 9) within the head forms a complete closure ring.</p> |
