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 body portion;

an anvil assembly movably mounted at a 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 assembly toward and away from the body portion;

a dispersion assembly operatively associated with the approximation assembly, the dispersion assembly including at least one angled surface relative to the longitudinal axis of the body portion defining at least one channel interposed between the anvil assembly and the body portion and being configured to dispense a fluid therefrom, wherein the dispersion assembly includes a manifold having a plurality of ejection ports for dispensing;

a first wound treatment material; and

a second wound treatment material; and

at least one conduit for conducting the first and second wound treatment material to the dispersion assembly,

wherein a distal end portion of the manifold is tapered at an angle relative to the longitudinal axis of the body portion.

2. The apparatus according to claim 1, wherein the at least one conduit includes:

a first conduit having a distal end in fluid communication with a plurality of first ejection ports formed in the manifold; and

a second conduit having a distal end in fluid communication with a plurality of second ejection ports formed in the manifold.

3. The apparatus according to claim 2, the plurality of first ejection ports and the plurality of second ejection ports are disposed in the distal end portion of the manifold.

4. The apparatus according to claim 3, wherein the dispersion assembly further includes:

a cap operatively connected to the distal end of the manifold in such a manner so as to define a channel between an outer surface of the distal end portion of the manifold and an inner surface of the cap.

5. The apparatus according to claim 2, further comprising:

a third conduit having a distal end in fluid communication with a third ejection port.

6. The apparatus according to claim 5, wherein the first conduit is connectable to a first fluid source, the second conduit is connectable to a second fluid source, and the third conduit is connectable to a third fluid source.

7. The apparatus according to claim 6, 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.

8. The apparatus according to claim 7, wherein the multi-part wound treatment material is a sealant.

9. The apparatus according to claim 6, wherein the third source includes a fluid.

10. The apparatus according to claim 4, wherein the cap and the distal end portion of the manifold are shaped so that the channel directs the fluid in a substantially proximal direction.

11. The apparatus according to claim 7, wherein the fluid ejected from the channel causes the first and second parts of the multi-part wound treatment material to mix.

12. The apparatus according to claim 1, further comprising an actuation assembly having at least one handle connected to the body portion.

13. The apparatus according to claim 12, wherein the approximation assembly includes:

a threaded rod member threadingly engaging the at least one handle; and

a knob member operatively connected to a proximal end of the threaded rod member.

14. The apparatus according to claim 13, wherein the dispersion assembly is operatively associated with the distal end of the threaded rod member.

15. The apparatus according to claim 14, wherein the threaded rod member includes windows formed on opposite sides thereof, wherein the windows are in registration with the at least one ejection port.

16. The apparatus according to claim 15, wherein the distal end of the threaded rod member comprises a connection member defining the windows, wherein a distal end of the connection member is configured to selectively engage a stem of an anvil assembly.

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

a body portion;

an anvil assembly movably mounted at a 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 assembly toward and away from the body portion;

a dispersion assembly operatively associated with the approximation assembly, the dispersion assembly including;

a manifold having a plurality of ejection ports for dispensing at least a first and second wound treatment material;

a cap operatively connected a distal end of the manifold; and

a channel defined by a surface of the manifold and an inner surface of the cap for dispensing a fluid therefrom.

18. The apparatus according to claim 17, wherein the channel is angled at approximately fifteen degrees relative to the central longitudinal axis of the manifold.

19. The apparatus according to claim 17, wherein the channel is angled between approximately zero and approximately fifteen degrees relative to a central longitudinal axis of the manifold.

20. The apparatus according to claim 17, wherein the channel is angled between approximately fifteen and approximately ninety degrees relative to a central longitudinal axis of the manifold.
