Surgical stapling apparatus having a wound closure material applicator assembly
View Patent ↗This disclosure relates to surgical stapling apparatus for enhancing one or more properties of body tissue that is or is to be repaired or joined. The apparatus includes a staple anvil, a staple cartridge, a driving member for driving the surgical staples from individual staple slots in the staple cartridge and against the staple anvil, and a wound closure material applicator assembly. The applicator assembly includes at least one conduit extending along at least a length of the driving member, anvil and/or cartridge and at least one reservoir in fluid communication with the at least one conduit, the reservoir containing a wound closure material therein. The staples can be coated with a wound closure material.
1. A surgical stapling apparatus for enhancing one or more properties of body tissue that is or is to be repaired or joined, the surgical stapling apparatus comprising:
a staple anvil positioned on a distal end of the stapling apparatus and having a working surface;
a staple cartridge positioned adjacent a distal end of the stapling apparatus and juxtaposable relative to the staple anvil, the staple cartridge including:
a working surface; one or more rows of individual staple slots formed in the working surface; and
a plurality of surgical staples individually disposed within the individual staple slots;
a driving member for firing the surgical staples from the individual staple slots and against the staple anvil; and
a wound closure material applicator assembly operatively associated with the stapling apparatus, the applicator assembly including:
at least one conduit extending along at least a length of the driving member; and
at least one reservoir in fluid communication with the at least one conduit, the reservoir containing a dispensable wound closure material therein, and the conduit having at least one opening and being adapted to provide wound closure material therethrough to an area between the working surface of the staple anvil and the staple cartridge, wherein the at least one conduit includes a plurality of openings formed therein for dispensing the wound closure material therefrom, and
wherein longitudinal translation of the driving member causes longitudinal translation of the at least one conduit across at least some of the individual staple slots, such that at least one of the plurality of openings is in communication with at least one of the staple slots.
2. The surgical stapling apparatus as claimed in claim 1 , wherein the at least one reservoir is compressible, and wherein compression of the at least one reservoir causes the wound closure material to be dispensed from the at least one opening of the at least one conduit.
3. A surgical stapling apparatus for enhancing one or more properties of body tissue that is or is to be repaired or joined, the surgical stapling apparatus comprising:
a staple anvil positioned on a distal end of the stapling apparatus and having a working surface;
a staple cartridge positioned adjacent a distal end of the stapling apparatus and juxtaposable relative to the staple anvil, the staple cartridge including:
a working surface;
one or more rows of individual staple slots formed in the working surface thereof; and
a plurality of surgical staples individually disposed within the individual staple slots;
a driving member for firing the surgical staples from the individual staple slots and against the staple anvil; and
a wound closure material applicator assembly operatively associated with the stapling apparatus, the applicator assembly including:
at least one conduit extending along at least a length of the driving member and being longitudinally movable therewith; and
at least one reservoir in fluid communication with the at least one conduit, the reservoir containing a dispensable wound closure material therein, and the conduit having a plurality of openings, the plurality of openings being adapted to dispense wound closure material therethrough to an area between the working surface of the staple anvil and the staple cartridge.
4. The surgical stapling apparatus as claimed in claim 3 , wherein longitudinal translation of the driving member causes longitudinal translation of the at least one conduit across at least some of the individual staple slots, such that at least one of the plurality of openings is in communication with at least one of the staple slots.
5. The surgical stapling apparatus as claimed in claim 3 , wherein the at least one reservoir is compressible, and wherein compression of the at least one reservoir causes the wound closure material to be dispensed from the at least one opening of the at least one conduit.
