Abstract

A surgical instrument for the removal of biological material from a patient. The surgical instrument includes a specimen retrieval bag having a flexible wall and a closed end and an open end, wherein the open end is for receiving biological materials. The instrument includes a noose adjacent to the open end, wherein the noose constricts the open end to substantially close the open end. The bag includes a row of alternating flexible and stiff areas on its wall adjacent to and about a periphery of th e open end, whereby when the open end is noosed, the flexible areas buckle before the stiff areas.

Claims (15)

1. A surgical instrument for the removal of biological material from a patient, the surgical instrument comprising:

a) a specimen retrieval bag having a flexible wall and a closed end and an open end, said open end for receiving biological materials therein;

b) a noose adjacent to said open end, said noose constricts said open end to substantially close said open end;

c) a row of alternating flexible and stiff areas on said wall adjacent to and about a periphery of said open end, whereby when said open end is noosed, said flexible areas buckle before said stiff areas.
2. The surgical instrument of claim 1 wherein said noose is between said open end and said a row of alternating flexible and stiff areas on said wall.
3. The surgical instrument of claim 2 wherein said flexible areas have a length longer than a length of said stiff areas.
4. The surgical instrument of claim 1 wherein said stiff areas have a thickness greater than a thickness of said flexible areas in said wall.
5. The surgical instrument of claim 1 wherein said stiff areas are of a different durometer than said flexible areas in said wall.
6. The surgical instrument of claim 1 wherein said stiff areas comprise shapes embossed in said wall.
7. The surgical instrument of claim 1 wherein said stiff areas comprise glue attached to said wall.
8. A surgical instrument for the removal of biological material from a patient, the surgical instrument comprising:

a) a specimen retrieval bag having a flexible wall and a closed end and an open end, said open end for receiving biological materials therein;

b) a noose adjacent to said open end, said noose constricts said open end to substantially close said open end; and c) first and second rows of alternating flexible and stiff areas on said wall on either side of said noose.
9. The surgical instrument of claim 8 wherein said flexible areas on said first row are staggered from said flexible areas on said second row.
10. The surgical instrument of claim 8 wherein said noose is between said open end and said a row of alternating flexible and stiff areas on said wall.
11. The surgical instrument of claim 10 wherein said flexible areas have a length longer than a length of said stiff areas.
12. The surgical instrument of claim 8 wherein said stiff areas have a thickness greater than a thickness of said flexible areas in said wall.
13. The surgical instrument of claim 8 wherein said stiff areas are of a different durometer than said flexible areas in said wall.
14. The surgical instrument of claim 8 wherein said stiff areas comprise shapes embossed in said wall.
15. The surgical instrument of claim 8 wherein said stiff areas comprise glue attached to said wall.
