Abstract

An assembly for joining tissue is provided and includes an anvil assembly and a body portion juxtaposed with respect to one another along a shaft and arranged so as to be approximated with respect to one another; and an applicator supported on the anvil assembly and configured for retaining a wound treatment material therein and for dispensing the wound treatment material therefrom. A method for joining tissue is provided and includes the steps of dispensing the wound treatment material from the applicator so as to distribute wound treatment material onto at least one of a first tissue section and a second tissue section; and approximating the anvil assembly and the body portion to one another so that the first tissue section and the second tissue section are in contact with one another with the dispensed wound treatment material interposed therebetween.

Claims

1. A surgical stapling device for joining tissue portions, comprising:

a handle assembly;

an anvil assembly at a distal end of the stapling device, the anvil assembly having a shaft for removably connecting the anvil assembly to the stapling device;

a tubular body portion, the tubular body portion having a staple cartridge assembly containing a plurality of surgical staples in an annular array, the anvil assembly and tubular body portion being juxtaposed with respect to one another along the shaft and arranged so as to be approximated with respect to one another; and

an applicator supported on the shaft of the anvil assembly, the applicator having a disc-shaped structure disposed between the anvil member and tubular body portion, the disc-shaped structure having a channel radially oriented and open at lateral sides of the disc-shaped structure, the channel being arranged for dispensing a wound treatment material.

2. The surgical stapling device according to claim 1, wherein the handle assembly includes a grip that is used to approximate the anvil assembly and tubular body portion.

3. The surgical stapling device according to claim 1, wherein the disc-shaped structure is substantially rigid.

4. The surgical stapling device according to claim 1, wherein the wound treatment material is at least one of an adhesive, a sealant, a hemostat, and a medicament.

5. The surgical stapling device according to claim 1, wherein the applicator includes a sleeve operatively connected to the anvil assembly.

6. The surgical stapling device according to claim 5, wherein the channel is in fluid communication with the sleeve.

7. The surgical stapling device according to claim 6, wherein the wound treatment material is retained within and dispensed from the sleeve.

8. The surgical stapling device according to claim 7, wherein the channel is in fluid communication with the sleeve.

9. The surgical stapling device according to claim 5, wherein the applicator includes an ampoule selectively positionable within the sleeve, wherein the wound treatment material is retained within and dispensed from the ampoule.

10. The surgical stapling device according to claim 9, wherein the shaft and the sleeve form a plunger for compressing the amouple and dispensing the wound treatment material.

11. The surgical stapling device according to claim 5, wherein the sleeve includes a portion through which the interior of the tubular sleeve is visible.

12. The surgical stapling device according to claim 11, wherein the sleeve selectively engages a connection member of the surgical stapling device.

13. The surgical stapling device according to claim 5, wherein the disc-shaped structure is supported on the distal end of the sleeve.

14. The surgical stapling device according to claim 1, wherein the disc-shaped structure includes a manifold supported on the anvil assembly, wherein the manifold defines the channels therein for directing a flow of wound treatment material onto an interface between the tissue portions.

15. The surgical stapling device according to claim 1, wherein the applicator includes a seal.

16. The surgical stapling device according to claim 1, further comprising an annular knife disposed radially inwardly of the staples.
