Abstract

According to an aspect of the present disclosure, an apparatus for forming an anastomosis between adjacent sections of tissue is provided. The apparatus includes a body portion; an actuation assembly operatively supported at a proximal end of the body portion; an anvil assembly movably mounted at the distal end of the body portion for movement toward and away from the body portion; an approximation assembly extending between the body portion and the anvil assembly for moving the anvil toward and away from the tubular body portion; a dispersion assembly operatively associated with the approximation assembly, the dispersion assembly including at least one angled surface defining at least one channel interposed between the anvil assembly and the body portion and being configured to dispense a fluid therefrom; and at least one conduit for conducting wound treatment material to the dispersion assembly.

Claims

1. An apparatus for forming an anastomosis between adjacent sections of tissue, comprising:

(a) a body portion and an approximation shaft associated with the body portion;

(b) an anvil assembly movably mounted at a distal end of the body portion for movement toward and away from the body portion;

(c) a system operatively associated with the approximation shaft, the system including at least one angled surface defining at least one channel interposed between the anvil assembly and the body portion and being configured to dispense a fluid therefrom, wherein the system includes;

(i) a plurality of ejection ports for dispensing wound treatment material in a radial direction;

(ii) a conduit communicating with the channel for dispensing a gas; and

(iii) at least one second conduit for conducting wound treatment material to the plurality of ejection ports.

2. The apparatus according to claim 1, wherein the apparatus has a pusher for firing staples.

3. The apparatus according to claim 1, wherein the apparatus has an approximation assembly extending between the body portion and the anvil assembly for moving the anvil assembly toward and away from the body portion.

4. The apparatus according to claim 1, a manifold and a cap defining the channel therebetween for dispensing the gas, the gas being dispensed in a direction toward the plurality of ejection ports.

5. The apparatus according to claim 1, wherein the at least one angled surface is tapered at an angle relative to a longitudinal axis of the body portion, and the plurality of ejection ports are defined in the angled surface.

6. The apparatus according to claim 1, further comprising a fluid source.

7. The apparatus according to claim 6, wherein the fluid source is a first fluid source containing a first part of a multi-part wound treatment material, and further comprising a second fluid source having a second part of the multi-part wound treatment material.

8. The apparatus according to claim 1, wherein the wound treatment material is a sealant.

9. The apparatus according to claim 1, wherein the wound treatment material is an adhesive.

10. The apparatus according to claim 1, wherein the wound treatment material is a medicament.

11. An apparatus for forming an anastomosis between adjacent sections of tissue, comprising:

(a) a body portion and an approximation shaft including a trocar, the trocar being configured to selectively engage a stem of an anvil assembly;

(b) an anvil assembly mountable to the approximation shaft for movement toward and away from the body portion;

(c) a dispersion assembly operatively associated with the trocar of the approximation shaft;

(i) the dispersion assembly including at least one angled surface on the trocar, wherein the dispersion assembly includes;

a plurality of ejection ports for dispensing wound treatment material defined in a surface of the trocar and being directed toward the at least one angled surface;

the plurality of first ejection ports being oriented in a radial direction; and

at least one source of wound treatment material to the dispersion assembly.

12. The apparatus according to claim 11, wherein a distal end of the trocar defines a penetrating tip.

13. The apparatus according to claim 12, wherein the at least one angled surface defines a conical shape positioned proximally of the penetrating tip.

14. The apparatus according to claim 11, wherein the trocar is hollow, the trocar being the at least one source of wound treatment material.

15. The apparatus according to claim 14, wherein the trocar receives an ampoule of wound treatment material.

16. The apparatus according to claim 15, wherein the ampoule is compressible.

17. The apparatus according to claim 16, wherein the dispersion assembly includes a plunger disposed in the trocar.

18. The apparatus according to claim 17, wherein the plunger forms a fluid tight seal with the trocar.

19. The apparatus according to claim 18, wherein the trocar defines a pocket and the ampoule has a nub received in the pocket.

20. The apparatus according to claim 15, wherein the trocar defines a cavity for receiving the ampoule and the cavity communicates with the at least one conduit.
