Abstract

A surgical access device includes a cannula body, an anchor, and a first suture retention mechanism. The cannula body includes a housing and an elongated portion extending distally from the housing. The elongated portion defines a longitudinal axis and a channel extending therethrough. The anchor is disposed in mechanical cooperation with the elongated portion of the cannula body and is longitudinally translatable relative to the elongated portion. The first suture retention mechanism extends laterally from the anchor. A suture-receiving channel is defined between a portion of the suture retention mechanism and a portion of the anchor.

Claims (24)

1. A surgical access device, comprising:

a cannula body including a housing and an elongated portion extending distally from the housing, the elongated portion defining a longitudinal axis;

a first suture retention mechanism positioned radially outward of the elongated portion of the cannula body; and

a foam sleeve radially surrounding at least a portion of the elongated portion of the cannula body and positioned distally of the first suture retention mechanism, wherein the foam sleeve is configured to be passed through by a suture.

2. The surgical access device according to claim 1 , further comprising a suture-receiving channel defined between the first suture retention mechanism and the elongated portion of the cannula body.

3. The surgical access device according to claim 2 , wherein the suture-receiving channel is ring-shaped.

4. The surgical access device according to claim 1 , wherein the first suture retention mechanism includes a cylindrical shoulder.

5. The surgical access device according to claim 4 , wherein the first suture retention mechanism includes a disc-shaped arm extending laterally from the cylindrical shoulder.

6. The surgical access device according to claim 5 , further comprising a suture-receiving channel defined between the first suture retention mechanism and the elongated portion of the cannula body, wherein the suture-receiving channel is ring-shaped, the suture-receiving channel surrounds the cylinder shoulder, and the suture-receiving channel is disposed between the disc-shaped arm and the elongated portion of the cannula body.

7. The surgical access device according to claim 4 , further comprising a suture-receiving channel defined between the first suture retention mechanism and the elongated portion of the cannula body, wherein the suture-receiving channel surrounds the cylindrical shoulder.

8. The surgical access device according to claim 1 , further including a second suture retention mechanism disposed in mechanical cooperation with first suture retention mechanism.

9. The surgical access device according to claim 8 , wherein the second suture retention mechanism is fixed from movement relative to the first suture retention mechanism.

10. The surgical access device according to claim 1 , wherein the foam sleeve extends farther from the longitudinal axis than the first suture retention mechanism.

11. A surgical access device, comprising:

a cannula defining a longitudinal axis;

a first suture retention mechanism disposed in mechanical cooperation with the cannula and being longitudinally translatable relative to the cannula, wherein a suture-receiving channel is defined between a portion of the first suture retention mechanism and a portion of the cannula; and

a sleeve disposed in mechanical cooperation with the cannula and being longitudinally translatable relative to the cannula, wherein the sleeve extends farther from the longitudinal axis than the first suture retention mechanism, wherein the sleeve is configured to be passed through by a suture.

12. The surgical access device according to claim 11 , wherein the sleeve is made from foam.

13. The surgical access device according to claim 11 , wherein the suture-receiving channel is ring-shaped.

14. The surgical access device according to claim 11 , wherein the first suture retention mechanism includes a cylindrical shoulder.

15. The surgical access device according to claim 14 , wherein the first suture retention mechanism includes a disc-shaped arm extending laterally from the cylindrical shoulder.

16. The surgical access device according to claim 11 , wherein the first suture retention mechanism includes a cylindrical shoulder, and wherein the suture-receiving channel surrounds the cylindrical shoulder.

17. The surgical access device according to claim 11 , further including a second suture retention mechanism disposed in mechanical cooperation with the first suture retention mechanism.

18. The surgical access device according to claim 17 , wherein the second suture retention mechanism is fixed from movement relative to the first suture retention mechanism.
