Abstract

A specimen retrieval pouch (pouch) is provided. The pouch including a closed bottom portion, an open upper portion and an elongated tube operably coupled to an interior wall of the pouch. The elongated tube has a plurality of openings positioned along a length thereof. A suture accessible at a proximal end of the pouch is positioned within the elongated tube and extends past a distal end thereof. The suture is movable within the elongated tube and relative to the pouch. The suture has either a needle or a loop at a distal end thereof for attaching to tissue and subsequently drawing the tissue into the pouch when the suture is pulled. One or more reinforced tabs are operably disposed on the pouch. The reinforced tab(s) is/are configured to be grasped by a user to provide a counter pull force as the suture is being pulled through the elongated tube.

Claims

1. A specimen retrieval pouch, comprising:

a closed bottom portion and an open upper portion, the specimen retrieval pouch including an elongated tube and a plurality of welds intermittently connecting the elongate tube to an interior wall of the specimen retrieval pouch and extending along a length thereof, the elongated tube having a plurality of openings positioned along a length thereof;

a suture accessible at a proximal end of the surgical retrieval pouch and positioned within the elongated tube and extending past a distal end thereof, the suture movable within the elongated tube and relative to the specimen retrieval pouch, the suture having one of a needle and a loop at a distal end thereof for attaching to tissue and subsequently drawing the tissue into the specimen retrieval pouch when the suture is pulled though the elongated tube; and

at least one reinforced tab operably disposed on an exterior wall of the specimen retrieval pouch, the at least one reinforced tab configured to be grasped by a user to provide a counter pull force as the suture is being pulled through the elongated tube.

4. A specimen retrieval pouch according to claim 1, wherein at least the interior wall is textured.

5. A specimen retrieval pouch according, to claim 1, wherein the specimen retrieval pouch is wider at the open upper portion and tapers toward the closed bottom portion.

6. A specimen retrieval pouch according to claim 1, wherein the plurality of openings are configured to permit air therethrough when tissue is being drawn into the specimen retrieval pouch to facilitate positioning the tissue within the specimen retrieval pouch.

7. A specimen retrieval pouch according to claim 6, wherein the plurality of openings are positioned radially along the length of the elongated tube forming a generally spiral configuration.

8. A specimen retrieval pouch according to claim 1, wherein the plurality of welds are configured and dimensioned to facilitate air evacuation from the specimen retrieval pouch and to provide structural support to the specimen retrieval pouch while tissue is being drawn into the specimen retrieval pouch.

9. A specimen retrieval pouch according to claim 1, wherein the at least one reinforced tab includes at least one opening defined therethrough to facilitate grasping thereof by the user.

10. A specimen retrieval pouch according to claim 9, wherein the at least one reinforced tab extends along a length of the specimen retrieval pouch and defines a plurality of openings therethrough.

2. A specimen retrieval pouch according to claim l, wherein the specimen retrieval pouch is constructed from at least two sheets of plastic that are joined together forming the interior and exterior walls.

3. A specimen retrieval pouch according to claim 2, wherein the at least two sheets of plastic are joined together via one of welding and adhesive.

11. A specimen retrieval device, comprising:

an applicator;

a specimen retrieval pouch operably disposed within the applicator and deployable therefrom, the specimen retrieval pouch defining a longitudinal axis therethrough and including a closed bottom portion and an open upper portion, the specimen retrieval pouch including an elongated tube and a plurality of welds intermittently connecting the elongate tube to an interior wall of the specimen retrieval pouch, the elongated tube having open proximal and distal ends and a plurality of openings positioned along a length thereof between the open proximal and distal ends; and

a suture positioned within the specimen retrieval pouch and accessible at a proximal end thereof, the suture configured to attach to tissue for drawing the tissue into the specimen retrieval pouch when the suture is pulled though the elongated tube.

12. A specimen retrieval device according to claim 11, wherein the specimen retrieval pouch is wider at the open upper portion and tapers toward the closed bottom portion.

13. A specimen retrieval device according to claim 11, wherein the plurality of openings are configured to permit air therethrough when tissue is being drawn into the specimen retrieval pouch to facilitate positioning the tissue within the specimen retrieval pouch.

14. A specimen retrieval device according to claim 13, wherein the plurality of openings are positioned radially along the length of the elongated tube forming a generally spiral configuration.

15. A specimen retrieval device according to claim 11, wherein the plurality of welds are configured and dimensioned to facilitate air evacuation from the specimen retrieval pouch and to provide structural support to the specimen retrieval pouch while tissue is being drawn into the specimen retrieval pouch.

16. A specimen retrieval device according to claim 11, wherein a needle is operably coupled to a distal end of the suture for attaching to tissue.

17. A. specimen retrieval device according to claim 11, wherein a distal end of the suture is looped for attaching to tissue.

18. A specimen retrieval device according to claim 11, further comprising at least one reinforced tab operably disposed on the specimen retrieval pouch, the at least one reinforced tab configured to be grasped by a user to provide a counter pub force as the suture is being pulled through the elongated tube, wherein the at least one reinforced tab is operably disposed on an exterior wall of the specimen retrieval pouch and adjacent the closed bottom portion thereof, wherein the at least one reinforced tab includes at least one opening defined therethrough to facilitate grasping thereof by the user.

19. A specimen retrieval device, comprising:

an applicator;

a specimen retrieval pouch operably disposed within the applicator and deployable therefrom, the specimen retrieval pouch defining a longitudinal axis therethrough and including a closed bottom portion and an open upper portion, the specimen retrieval pouch including an elongated tube and a plurality of welds intermittently connecting the elongate tube to an interior wall of the specimen retrieval pouch and extending along a length of specimen retrieval pouch, the elongated tube having open proximal and distal ends and a plurality of openings positioned along a length thereof between the open proximal and distal ends; and

a suture accessible at a proximal end of the specimen retrieval pouch and positioned within the elongated tube and extending past a distal end thereof, the suture movable within the elongated tube and relative to the specimen retrieval pouch for attaching to tissue and subsequently drawing the tissue into the specimen retrieval pouch when the suture is pulled.
