Abstract

An intestinal intraluminal reconstruction and resection device includes a mechanism for intussusception of the bowel, a bowel anastomosis mechanism and a mechanism for severing the resected bowel. The surgical device allows the user to carry out intraluminally an anastomosis first, prior to resection of the intestine or any hollow viscus, therefore not exposing the dirty intraluminal content to the clean abdominal or thoracic cavities. The above is achieved by first intussuscepting the hollow viscus, then anastomosis and finally intraluminal resection.

Claims

1. A surgical intraluminal resection and reconstruction device comprising:

a housing;

a luminal attachment and intussusception means coupled to said housing for attachment and inversion of a portion of the lumen to be removed;

a luminal anastomosis means coupled to said housing for attaching the lumen wall together prior to completion of resection; and

a resection means coupled to said housing for severing the intussuscepted portion of the lumen after the anastomosis without opening the lumen.

2. The surgical device of claim 1 wherein said luminal anastomosis means and said resection means are movable relative to said luminal attachement and intussusception means.

3. The surgical device of claim 2 wherein said luminal attachment and intussusception means includes a central post adapted to have the lumen attached thereto.

4. The surgical device of claim 2 wherein said luminal attachment and intussusception means includes a groove on said housing.

5. The surgical device of claim 2 wherein said luminal anastomosis means includes a stapling head and an anvil.

6. The surgical device of claim 5 wherein said stapling head is an annular structure adapted to surround said anvil.

7. The surgical device of claim 5 wherein said resection device of claim 5 wherein said reception means includes a radially movable annular knife.

8. The surgical device of claim 5 wherein said stapling head includes two annular rows of staples adapted to fire against said anvil.

9. The surgical device of claim 1 further including a band for attaching the lumen to said luminal attachment and intussusception means.

10. The surgical device of claim 9 further including means coupled to said housing for holding said attachment band prior to use of said attachment band.

11. A surgical intraluminal resection and reconstruction device comprising:

a housing;

a luminal attachment and intussusception means coupled to said housing for attachment and inversion of a portion of the lumen to be removed; and

a luminal anastomosis means coupled to said housing for attaching the lumen wall together prior to completeness of resection, wherein said luminal anastomosis means is movable relative to said luminal attachment and intussusception means.

12. The surgical device of claim 11 further including a resection means for severing the portion of the lumen to be removed wherein said resection means is adapted to resect the lumen substantially simultaneously with the attaching of the lumen wall by said anastomosis means.

13. The surgical device of claim 11 wherein said luminal anastomosis means includes a stapling head and anvil.

14. The surgical device of claim 13 wherein said stapling head is an annular structure adapted to surround said anvil.

15. A surgical intraluminal resection and reconstruction device comprising:

a housing;

a luminal attachment member coupled to said housing, said luminal attachment member adapted to have a lumen portion attached thereto; and

a stapling assembly movable relative to said luminal attachment member, wherein relative movement between said stapling assembly and said luminal attachment member operates to invert a portion of the lumen.

16. The device of claim 15 wherein said luminal attachment member includes a movable central post.

17. The device of claim 15 wherein said luminal attachment member includes a groove in said housing.

18. The device of claim 15 further including a retractable knife for severing a portion of the lumen to be removed.

19. The device of claim 15 further including a band for attaching the lumen to said lumen attaching member and a carrier for said band.

20. The device of claim 15 further including a lumen severing wire for cutting a portion of the lumen to be removed.
