Surgical access assembly with sleeve and adjustable fastener
A surgical access assembly and method of use is disclosed, including an access member, a tissue engaging member, a sleeve extending from a portion of the membrane, and a fastening member to couple the access member and the sleeve. The access member includes proximal and distal ends, at least one lumen disposed therethrough, and defines a longitudinal axis. The tissue engaging member includes a membrane having proximal and distal ends with opposing openings, and a passage therethrough for receiving the access member. A length of the tissue engaging member may be selectively adjustable by a user so as to provide a retraction force. The sleeve extends proximally from a portion of the membrane. The sleeve has a proximal end and a distal end with opposing openings, the distal end of the sleeve defined by a portion of the membrane. A fastening member couples the access member and the sleeve.
1. A surgical access assembly comprising:
a proximal ring positionable against an outer surface of body tissue;
a distal ring positionable against an inner surface of body tissue;
a membrane having a proximal end and a distal end defining a passage therethrough, the distal end of the membrane coupled to the distal ring and the proximal end of the membrane coupled to the proximal ring, a length of the membrane being selectively adjustable;
a sleeve having a proximal end and a distal end defining a channel therethrough, the distal end of the sleeve coupled to the distal ring and the proximal end positionable proximally of the proximal ring, the channel of the sleeve located in the passage of the membrane; and
an access member having proximal and distal ends, the access member positionable in the channel of the sleeve, the access member securable to the sleeve.
2. The surgical access assembly of claim 1 , wherein the access member includes a least one lumen extending therethrough.
3. The surgical access assembly of claim 1 , further comprising a fastening member for securing the access member in the channel of the sleeve.
4. The surgical access assembly of claim 1 , wherein the access member, the sleeve, and the membrane form a fluid-tight seal between the outer surface of body tissue and the inner surface of body tissue.
5. The surgical access assembly of claim 3 , wherein the fastening member is disposed in a pocket located on a surface of the sleeve.
6. The surgical access assembly of claim 5 , wherein the fastening member is configured to be tightened to secure a position of the access member relative to the pocket.
7. The surgical access assembly of claim 5 , wherein the pocket has at least one opening for receiving an end of the fastening member.
8. The surgical access assembly of claim 1 , wherein the proximal ring is configured for repeated eversion to adjust a length of the sleeve.
9. The surgical access assembly of claim 8 , wherein the access member is positionally fixed relative to the sleeve such that repeated eversion of the proximal ring moves the access member relative to the distal ring.
10. The surgical access assembly of claim 1 , wherein repeated eversion of the proximal ring adjusts a length of the sleeve and the length of the membrane.
11. The surgical access assembly of claim 1 , wherein rolling the proximal ring adjusts the length of the membrane so as to provide a retraction force.
12. The surgical access assembly of claim 6 , wherein the fastening member includes a grooved surface and a receiving member that securely engages the grooved surface.
13. The surgical access assembly of claim 6 , wherein the fastening member further includes angled ridges and a pawl, the pawl attached to a release member.
14. The surgical access assembly of claim 1 , wherein the access member is securable against an inner surface of the sleeve.
15. The surgical access assembly of claim 1 , wherein the distal end of the access member is positionable distally of the proximal ring.
