Surgical access assembly with sleeve and adjustable fastener

1. A surgical access assembly, comprising:

an access member having proximal and distal ends, at least one lumen therethrough, and defining a longitudinal axis;

a tissue engaging member including a membrane having proximal and distal ends with opposing openings and a passage therethrough for receipt of the access member, a length of the tissue engaging member being selectively adjustable by a user so as to provide a retraction force;

a sleeve extending proximally from a portion of the membrane, the sleeve having a proximal end and a distal end with opposing openings, the distal end of the sleeve defined by a portion of the membrane, the sleeve having a passage therethrough to receive the access member; and

a fastening member for securing the access member within the sleeve.

2. The surgical access assembly of claim 1 , wherein an outer circumference of the sleeve has a channel to receive the fastening member.

3. The surgical access assembly of claim 2 , wherein the channel has at least one opening.

4. The surgical access assembly of claim 1 , wherein the fastening member includes a grooved surface.

5. The surgical access assembly of claim 3 , wherein the fastening member includes angled ridges.

6. The surgical access assembly of claim 4 , wherein the fastening member includes a receiving member that securely engages the grooved surface.

7. The surgical access assembly of claim 5 , wherein the fastening member includes a pawl.

8. The surgical access assembly of claim 7 , wherein the pawl is attached to a release member.

9. The surgical access assembly of claim 1 , wherein the tissue engaging member contains a resilient annular member on at least one end.

10. The surgical access assembly of claim 7 , wherein the resilient annular member is fixably attached to at least one end of the membrane.

11. The surgical access member of claim 1 , wherein the fastening member includes connected protrusions.

12. The surgical access member of claim 11 , further including a receiving member that securely engages the protrusions.

13. The surgical access member of claim 1 , wherein the fastening member includes separable members, each separable member having a first protrusion connected to a second protrusion having an aperture.

14. The surgical access member of claim 13 , wherein the second protrusion securely engages the first protrusion of another separable member.

15. A method of placing a surgical access assembly, comprising:

sliding a proximal end of a tissue engaging member along an outer surface of a sleeve to define a tissue engaging member, the tissue engaging member including a membrane having proximal and distal ends with opposing openings and a passage therethrough, the sleeve having a proximal end and a distal end with opposing openings and extending from a portion of the membrane, the distal end of the sleeve defined by a surface of the tissue engaging member, the sleeve having a passage therethrough to receive an access member, the access member having proximal and distal ends, at least one lumen therethrough, and defining a longitudinal axis;

disposing excess material from the membrane or the sleeve over the proximal end of the membrane;

inserting the tissue engaging member into tissue;

inserting the access member into the sleeve;

securing the access member within the sleeve with a fastening member; and

inserting the access member and sleeve into the tissue engaging member.

16. The method of claim 15 , further including inserting surgical instruments through the access member.

17. The method of claim 16 , further including performing a minimally invasive procedure.

18. The method of claim 17 , further including removing surgical instruments from the access member.

19. The method of claim 18 , further including removing the access member from the sleeve.

20. The method of claim 15 , further including removing excess material from the sleeve.

21. The method of claim 15 , wherein an outer circumference of the sleeve has a channel to receive the fastening member, and the method further includes inserting the fastening member into the channel.
