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, comprising:

an anchor member including a longitudinal port defining a passage for reception of a surgical instrument in a sealing relation, the 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, such that the flexible sleeve may be rolled around the ring member to transition the flexible sleeve from a first length to a second length so as to position the anchor member at least partially within the tissue tract and thereby provide sealing engagement therebetween, the flexible sleeve defining a longitudinal passage having a second diameter larger than the first diameter of the longitudinal port of the anchor member.

2. The surgical apparatus according to claim 1, wherein the flexible sleeve has a generally cylindrical configuration.

3. The surgical apparatus according to claim 2, wherein the flexible sleeve is transitionable between 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.

4. The surgical apparatus according to claim 3, wherein the ring member has a non-circular cross-sectional shape configured to inhibit the sheath from unrolling.

5. The surgical apparatus according to claim 2, wherein the flexible sleeve is attached to the anchor member by glue, suture or an over molding process.

6. The surgical apparatus according to claim 2, wherein the ring member is configured for disposition exteriorly of the tissue tract.

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

8. A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, comprising:

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

a sheath having proximal and distal ends, the distal end of the sheath attached to the proximal end of the foam anchor member, the sheath having a rollable ring attached to the proximal end thereof, whereby rolling of the sheath about the rollable ring retracts the tissue tract such that the foam anchor member is drawn into sealing engagement with tissue defining the underlying body cavity, the sheath defining a longitudinal passage having a second diameter larger than the first diameter of the port.

9. The surgical apparatus according to claim 8, wherein the sheath is configured to roll along a longitudinal axis of the surgical apparatus.

10. The surgical apparatus according to claim 8, wherein the sheath is transitionable between 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.

11. The surgical apparatus according to claim 10, wherein the ring has a non-circular cross-sectional shape configured to inhibit the sheath from unrolling.

12. The surgical apparatus according to claim 11, wherein the ring defines a hole for receiving a suture therethrough.

13. The surgical apparatus according to claim 11, further comprising a suture to secure the sheath in the rolled state.

14. The surgical apparatus according to claim 8, wherein the sheath defines a generally cylindrical configuration.

15. The surgical apparatus according to claim 8, wherein the anchor member defines an hourglass configuration.

16. The surgical apparatus according to claim 8, wherein the anchor member is made of a sponge or rubber like material.

17. The surgical apparatus according to claim 8, wherein the sheath is attached to the anchor member by glue, suture or an over molding process.
