a wound treatment material dispersion assembly operatively associated with the approximation assembly, the dispersion assembly including;

at least one fluid source,

at least one conduit in fluid communication with the at least one fluid source and extending into the shaft of the approximation assembly; and

at least one ejection port formed in the shaft of the approximation assembly and being in fluid communication with the at least one conduit wherein the at least one ejection port is configured to dispense fluid from the at least one fluid source to a location between the staple pusher member and the anvil assembly.

2. The surgical apparatus according to claim 1, wherein the wound treatment material dispersion assembly includes:

a first fluid source containing a first fluid and a second fluid source containing a second fluid different from the first fluid;

a first conduit in fluid communication with the first fluid source and a second conduit in fluid communication with the second fluid source; and

at least one first ejection port in fluid communication with the first conduit and at least one second ejection port in fluid communication with the second conduit.

3. The surgical apparatus according to claim 2, wherein the wound treatment material dispersion assembly includes a plurality of first and second ejection ports.

4. The surgical apparatus according to claim 2, wherein the first fluid source includes a first part of a multi-part wound treatment material, and wherein the second fluid source includes a second part of the multi-part wound treatment material.

5. The surgical stapling apparatus according to claim 1, wherein the at least one ejection port is oriented to dispense fluid radially.

6. The surgical stapling apparatus according to claim 1, wherein the approximation assembly includes a nozzle supported on the shaft, and wherein the at least one ejection port is disposed within the nozzle of the approximation assembly.

7. The surgical stapling apparatus according to claim 6, wherein the nozzle of the approximation assembly includes a manifold having a plurality of ejection ports.

8. The surgical stapling apparatus according to claim 7, wherein the plurality of ejection ports include:

a plurality of first ejection ports for dispensing a first wound treatment material; and

a plurality of second ejection ports for dispensing a second wound treatment material different from the first wound treatment material.

9. The surgical stapling apparatus according to claim 8, wherein the first wound treatment material is a first part of a multi-part wound treatment material, and wherein the second wound treatment material is a second part of a multi-part wound treatment material.

10. The surgical stapling apparatus according to claim 8, wherein the wound treatment dispersion assembly includes a cap operatively connected to the manifold, and wherein the cap defines a channel between an inner surface of the cap and an outer surface of the manifold.

11. The surgical stapling apparatus according to claim 10, wherein the channel defines a third ejection port for dispensing a third wound treatment material.

12. The surgical stapling apparatus according to claim 11, wherein the third wound treatment material is a fluid for facilitating mixing of the first and second wound treatment materials.

13. The surgical stapling apparatus according to claim 1, wherein the shaft of the approximation assembly defines a longitudinal throughbore, and includes a trocar slidably received within the longitudinal throughbore.

14. The surgical stapling apparatus according to claim 13, wherein the trocar defines a cavity configured and dimensioned to receive the at least one fluid source.

15. The surgical stapling apparatus according to claim 14, wherein the at least one fluid source is an ampoule defining the at least one conduit having a lumen extending therethrough.

16. The surgical stapling apparatus according to claim 15, wherein the ampoule further includes a plunger slidably disposed within the lumen and forming a fluid tight seal with an inner surface of the lumen of the at least one conduit.

17. The surgical stapling apparatus according to claim 13, wherein the at least one ejection port is formed within the trocar.

18. The surgical stapling apparatus according to claim 14, wherein the at least one ejection port extends from the cavity of the trocar and branches off into a series of ejection ports formed radially around the trocar.
