Abstract
Abstract A surgical stapling apparatus comprising a permanent instrument and a disposable cartridge for anastomosing disconnected sections of hollow body organs. The instrument contains a body 330 defining a bore. A tubular member 350, received within the bore, is arranged for reciprocation motion. A first mechanism 314 is provided to reciprocate the tubular member 350 and thus drive the staples. Mounted concentrically within the tubular member is a rod 352, which includes first and second longitudinally extending keyways (458, 459, figures 1, 10, 20,) of different dimensions. A second mechanism 360 is provided to reciprocate the rod 352. The disposable cartridge 340 comprises a rigid staple- carrying part 344 and a rigid anvil- carrying part 346. The staple-carrying part and the anvil-carrying part each include first and second keys 687, 688 configured to mate, respectively, with the first and second keyways 458, 459 to directly mount the parts in a predetermined indexed orientation on the rod. Movement of rod 352 by screw 360 adjusts the separation of anvil corner 346 and staple corner 344 to facilitate gripping of the organs to be stapled. <IMAGE>
