Abstract

A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity is adapted to tissues having different thicknesses. The surgical apparatus includes an anchor member and a flexible sleeve integrated with the anchor member. The anchor member defines at least one longitudinal port for reception of a surgical instrument. The surgical apparatus defines an adjustable length to accommodate tissues with different thicknesses.

Claims

1. A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, which comprises:

an anchor member including at least one longitudinal port defining a passage for reception of a surgical instrument in a sealing relation, the at least one longitudinal port defining a first diameter; and

a flexible sleeve permanently attached to a proximal end portion of the anchor member, the flexible sleeve including a ring member attached to the flexible sleeve, the ring member adapted to be rolled such that the flexible sleeve may be rolled around the ring member to thereby transition the flexible sleeve from a first length to a second length so as to position the anchor member within the tissue tract, the flexible sleeve defining a longitudinal passage having a second diameter larger than the first diameter of the at least one longitudinal port.

2. The surgical apparatus according to claim 1, wherein the surgical apparatus defines an adjustable insertion length corresponding to tissue tracts of different thicknesses.

3. The surgical apparatus according to claim 1, wherein the flexible sleeve includes a sheath in a generally cylindrical configuration.

4. The surgical apparatus according to claim 3, wherein the ring member has a non-circular cross-sectional shape that maintains the sheath in a rolled position and helps prevent the sheath from unrolling.

5. The surgical apparatus according to claim 4, wherein the ring member is adapted for disposition exteriorly of the tissue tract.

6. The surgical apparatus according to claim 3, wherein the sheath defines an unrolled state that corresponds to the first length of the flexible sleeve and a rolled state that corresponds to the second length of the flexible sleeve, the first length is different from the second length.

7. The surgical apparatus according to claim 1, wherein the flexible sleeve is attached to the anchor member by glue, suture or an overmolding process.

8. The surgical apparatus according to claim 1, wherein the anchor member is adapted for disposition interiorly of the tissue tract.

9. The surgical apparatus according to claim 1, wherein the anchor member further includes a second longitudinal port.

10. A surgical apparatus defining a longitudinal axis for positioning within a tissue tract accessing an underlying body cavity, which comprises:

a foam anchor member defining a proximal end, a distal end, and including at least one longitudinal port defining a passage extending between the proximal and distal ends and being configured for reception of a surgical object in a sealing relation, the at least one longitudinal port including a first diameter; and

a sheath having a distal end and a proximal end, the distal end of the sheath attached to the proximal end of the foam anchor member, the sheath having a rollable ring attached at the proximal end thereof, the rolling of the sheath retracting an incision such that the foam anchor member is positioned below the incision, the sheath defining a longitudinal passage having a second diameter larger than the first diameter of the at least one longitudinal port.

11. The surgical apparatus according to claim 10, wherein the sheath is configured to roll upon itself along the longitudinal axis.

12. The surgical apparatus according to claim 10, wherein the surgical apparatus defines an adjustable length.

13. The surgical apparatus according to claim 12, wherein the sheath defines an unrolled state that corresponds to a first length of the surgical apparatus and a rolled state that corresponds to a second length of the surgical apparatus, the first length is different from the second length.

14. The surgical apparatus according to claim 13, wherein the rollable ring has a non-circular cross-sectional shape so as to prevent the sheath from transitioning from the rolled state towards the unrolled state.

15. The surgical apparatus according to claim 14, wherein the rollable ring defines a hole for receiving a suture therethrough.

16. The surgical apparatus according to claim 13, wherein the surgical apparatus further comprises a suture to secure the sheath in the rolled state.

17. The surgical apparatus according to claim 10, wherein the sheath defines a generally cylindrical configuration.

18. The surgical apparatus according to claim 10, wherein the surgical apparatus exhibits an hourglass configuration.

19. The surgical apparatus according to claim 10, wherein the foam anchor member is made of a sponge or rubber like material.

20. The surgical apparatus according to claim 10, wherein the sheath is attached to the foam anchor member by glue, suture or an overmolding process.
