Abstract

The present disclosure provides a surgical stapling device and a method for joining tissue portions. The surgical stapling device includes a handle assembly and a tubular body portion supported on a distal end of the handle assembly having a staple cartridge assembly containing a plurality of surgical staples in an annular array. An anvil assembly is at a distal end of the stapling device and has a shaft for removably connecting the anvil assembly to the tubular body portion. The anvil assembly and tubular body portion are juxtaposed with respect to one another along the shaft and are arranged so as to be approximated with respect to one another. A support member extends from the tubular body portion towards the anvil assembly and a buttress material is supported by the support member and removably attached to the support member.

Claims

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

a handle assembly;

a tubular body portion supported on a distal end of the handle assembly, the tubular body portion having a staple cartridge assembly containing a plurality of surgical staples in an annular array;

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 tubular body portion, 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;

a support member extending from the tubular body portion towards the anvil assembly; and

a buttress material supported by the support member and removably attached thereto, the buttress material being disposed between the anvil assembly and the staple cartridge assembly.

2. A surgical stapling device according to claim 1, wherein the buttress material includes an attachment member extending from the buttress material to the support member, the attachment member being attachable to the support member to removably secure the buttress material to the support member.

3. A surgical stapling device according to claim 1, wherein the tubular body portion includes a plurality of support members, the buttress material being removably attachable to the plurality of support members.

4. A surgical stapling device according to claim 1, wherein the support member is disposed in an opening extending at least partially through the tubular body portion.

5. A surgical stapling device according to claim 4, wherein the support member extends distally from the opening in an axial direction, a distal end of the support member being substantially radially aligned with a distal face of the tubular body portion.

6. A surgical stapling device according to claim 1, wherein the buttress material is positioned proximate to a tissue contacting surface of the staple cartridge assembly when the buttress material is attached to the support member.

7. A surgical stapling device according to claim 1, wherein the tubular body portion includes an elongate member extending axially therefrom, the elongate member defining a passage extending at least partially therethrough for reception of the shaft of the anvil assembly.

8. A surgical stapling device according to claim 7, wherein the support member is radially disposed between the elongate member and the staple cartridge assembly.

9. A surgical stapling device according to claim 7, wherein the tubular body portion further includes a knife disposed between the elongate member and the tubular body portion, the knife actuatable from a first proximal position to a second distal position to sever the tissue portions during firing of the surgical stapling device.

10. A surgical stapling device according to claim 9, wherein the support member is radially disposed between the elongate member and the knife.

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

a handle assembly;

a tubular body portion supported on a distal end of the handle assembly, the tubular body portion having a staple cartridge assembly containing a plurality of surgical staples in an annular array;

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 tubular body portion, 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;

an elongate member extending from the tubular body portion towards the anvil assembly, the elongate member including an opening extending at least partially therethrough for receiving the shaft of the anvil assembly; and

a buttress material supported by the elongate member and removably attached thereto, the buttress material being disposed between the anvil assembly and the staple cartridge assembly.

12. A surgical stapling device according to claim 11, wherein the elongate member defines a substantially circular platform at a distal end thereof, the buttress material being attachable to the circular platform.

13. A surgical stapling device according to claim 12, wherein the elongate member defines a proximal portion and a distal portion, the distal portion having an outer diameter which is larger than an outer diameter of the proximal portion, the circular platform being disposed on the distal portion.

14. A surgical stapling device according to claim 13, wherein the inner diameter of the proximal and distal portions are substantially the same.

15. A surgical stapling device according to claim 11, wherein the buttress material is adhered to a distal end of the elongate member.

16. A surgical stapling device according to claim 11, wherein a distal end of the elongate member is substantially radially aligned with a distal end of the staple cartridge assembly.

17. A method of using buttress material with a surgical stapling device, the method comprising the steps of:

positioning the buttress material at least partially between an anvil assembly and a cartridge assembly of the surgical stapling device and extending from the cartridge assembly to a support member of the surgical stapling device;

securing the buttress material to the support member;

receiving body tissue between the anvil assembly and the cartridge assembly;

grasping the body tissue between the anvil assembly and the cartridge assembly; and

firing the surgical stapling device to drive a plurality of staples from the cartridge assembly through the buttress material and the body tissue to thereby secure a first portion of the buttress material to the body tissue.

18. A method according to claim 17, wherein the step of firing the surgical stapling device includes the step of transitioning a knife between a first proximal position and a second distal position to sever the first portion of the buttress material from a second portion of the buttress material which is not secured to the body tissue, the second portion of the buttress material remaining secured to the support member.

19. A method according to claim 18, wherein the support member is disposed radially inward of the cartridge assembly with the knife disposed therebetween, the step of transitioning the knife including the step of the knife severing the buttress material extending between the cartridge assembly and the support member.

20. A method according to claim 18, wherein the second portion of the buttress material is a plurality of attachment members extending from the first portion of the buttress material to the support member, the step of transitioning the knife including the step of the knife severing the plurality of attachment members from the first portion of the buttress material.
