Surgical stapling apparatus having a wound closure material applicator assembly
First Claim
1. A surgical stapling apparatus for joining body tissue, comprising:
- a staple anvil positioned at a distal end of the stapling apparatus and having a knife track defined therein;
a staple cartridge positioned adjacent the staple anvil, the staple cartridge and staple anvil being juxtaposable relative to each other, the staple cartridge including a plurality of surgical staples individually disposed within individual staple slots formed in rows in the staple cartridge, and having a knife slot formed between adjacent rows of staples;
a driving member for firing the surgical staples from the individual staple slots and against the staple anvil;
a staple actuator having at least one cam wedge for ejecting staples and a knife blade, the staple actuator being movable along the staple rows; and
a wound closure material applicator assembly operatively associated with the stapling apparatus, the assembly including;
a conduit for conveying a wound closure material from a location external of the staple anvil and the staple cartridge to the staple actuator, wherein the conduit extends proximally from the staple actuator; and
a distribution tip in communication with the conduit and having an orifice, the conduit and the distribution tip being attached to the staple actuator so that the conduit and the distribution tip move along the staple rows with the staple actuator.
