Abstract

A surgical access assembly includes an access port and a seal anchor. The access port includes first and second rings and a sleeve extending between the first and second rings. In particular, the sleeve includes an inner surface having an attaching member. The seal anchor is adapted to be at least partially disposed in the access port. The seal anchor includes a base portion configured to detachably engage the attaching member of the access port.

Claims

1. A surgical access assembly comprising:

an access port including first and second rings and a sleeve extending between the first and second rings, the sleeve including an inner surface having an attaching member, the sleeve selectively rollable to adjust a position of the attaching member on the sleeve; and

a seal anchor adapted to be at least partially disposed in the access port, the seal anchor defining a lumen extending therethrough, the seal anchor including a base portion configured to detachably engage the attaching member of the access port, the seal anchor transitionable between an expanded condition and a deformed condition, wherein the base portion of the seal anchor includes a second attaching member adapted to be detachably attached to the attaching member of the access port, the second attaching member of the seal anchor disposed distal of the lumen of the seal anchor and in registration with the lumen of the seal anchor.

2. The surgical access assembly according to claim 1, wherein the second attaching member of the seal anchor is a refastenable tape.

3. The surgical access assembly according to claim 1, wherein the second attaching member of the seal anchor is a hook and loop fastener.

4. The surgical access assembly according to claim 1, wherein the base portion of the seal anchor defines a groove configured to receive the second attaching member of the seal anchor therein.

5. The surgical access assembly according to claim 1, wherein the lumen of the seal anchor is dimensioned to receive surgical instruments therethrough.

6. The surgical access assembly according to claim 1, wherein the second attaching member of the seal anchor defines a slit in alignment with the lumen.

7. The surgical access assembly according to claim 1, wherein the attaching member of the access port is a refastenable tape.

8. The surgical access assembly according to claim 1, wherein the attaching member of the access port is a hook and loop fastener.

9. The surgical access assembly according to claim 1, wherein the attaching member of the access port is an adhesive tape.

10. The surgical access assembly according to claim 1, wherein the attaching member of the access port is an annular ring disposed on the inner surface of the sleeve.

11. The surgical access assembly according to claim 1, wherein the first ring of the access port has a kidney shaped cross-sectional profile.

12. The surgical access assembly according to claim 11, wherein the second ring of the access port is an O-ring.

13. The surgical access assembly according to claim 12, wherein the second ring is an inflatable balloon.

14. The surgical access assembly according to claim 1, wherein the first and second rings are elastic.

15. The surgical access assembly according to claim 1, wherein the attaching member of the access port extends along a length of the sleeve of the access port.

16. The surgical access assembly according to claim 1, wherein the sleeve is made of an elastic material.

17. The surgical access assembly according to claim 1, wherein the seal anchor is made of a compressible material.

18. The surgical access assembly according to claim 1, wherein the second ring is an O-ring.
