Abstract

A surgical access attachment for use with a surgical access device is disclosed. The surgical access attachment includes a ring and an access portion assembly. The ring is configured to engage a proximal portion of a surgical access device. The access portion assembly includes at least one flexible tab having an engagement structure. The engagement structure is configured to selectively engage the ring. The access portion assembly is configured to retain a seal. The access portion assembly is configured to disengage from the ring in response to a predetermined amount of force exerted on one flexible tab of the at least one flexible tab.

Claims

1. A surgical access attachment for use with a surgical access device, the surgical access attachment comprising:

a ring configured to engage a proximal portion of a surgical access device;

an access portion assembly including at least one flexible tab having an engagement structure, the engagement structure being configured to selectively engage the ring, the access portion assembly configured to retain a seal;

wherein the access portion assembly is configured to disengage from the ring in response to a predetermined amount of force exerted on one flexible tab of the at least one flexible tab.

2. The surgical access attachment according to claim 1, wherein the access portion assembly is configured to disengage from the ring in response to a predetermined amount of proximally-directed force exerted on the one flexible tab of the at least one flexible tab.

3. The surgical access attachment according to claim 1, further comprising a lip disposed on the access portion assembly, the lip configured to selectively engage the ring.

4. The surgical access attachment according to claim 3, wherein the at least one flexible tab consists of one flexible tab, and wherein the lip is disposed 180°

from the flexible tab.

5. The surgical access attachment according to claim 4, wherein the access portion assembly consists of two features that are configured to removably engage the ring, the two features including the flexible tab and the lip.

6. The surgical access attachment according to claim 4, wherein a distal-most portion of the flexible tab is co-planar with a distal-most portion of the lip.

7. The surgical access attachment according to claim 4, wherein the ring includes a proximal wall, a distal wall, and an intermediate wall interconnecting the proximal wall and the distal wall, and wherein each of the lip and the flexible tab is configured to engage a distal surface of the proximal wall of the ring.

8. The surgical access attachment according to claim 1, wherein the ring includes a proximal wall, a distal wall, and an intermediate wall interconnecting the proximal wall and the distal wall, and wherein the proximal wall of the ring is configured to be positioned proximally of a proximal-most portion of a surgical access device.

9. The surgical access attachment according to claim 1, wherein the access portion assembly includes a proximal seal retaining portion and a distal seal retaining portion.

10. The surgical access attachment according to claim 9, wherein the at least one flexible tab extends from the proximal seal retaining portion.

11. The surgical access attachment according to claim 9, further comprising a lip disposed on the access portion assembly, the lip being configured to selectively engage the ring, wherein the at least one flexible tab extends from the proximal seal retaining portion, and wherein the lip extends from the distal seal retaining portion.

12. The surgical access attachment according to claim 9, wherein the at least one flexible tab extends from the proximal seal retaining portion and at least partially through an opening of the distal seal retaining portion.

13. The surgical access attachment according to claim 12, wherein the opening of the distal seal retaining portion is defined by a C-shaped projection extending radially outward from an outer ring of the distal seal retaining portion.

14. The surgical access attachment according to claim 9, wherein the proximal seal retaining portion includes a plurality of fingers, and wherein the distal seal retaining portion includes a plurality of engagement apertures, each finger of the plurality of fingers is configured to mechanically engage one engagement aperture of the plurality of apertures.

15. The surgical access attachment according to claim 1, wherein the access portion assembly is configured to engage the ring in a single-handed manner.

16. The surgical access attachment according to claim 15, wherein the access portion assembly is configured to disengage the ring in a single-handed manner.

17. The surgical access attachment according to claim 1, wherein the access portion assembly is configured to non-rotatably engage the ring in a single-handed manner.

18. The surgical access attachment according to claim 17, wherein the access portion assembly is configured to non-rotatably disengage the ring in a single-handed manner.
