Abstract

A surgical access apparatus includes an access member defining a longitudinal axis and having a longitudinal passageway for reception and passage of a surgical object and an access housing mountable to the access member. The access housing includes a diaphragm mounted thereto. The diaphragm is adapted for rotational movement about the longitudinal axis relative to the access housing. The diaphragm defines at least one internal pocket and has a seal assembly disposed within the internal pocket. The seal assembly has an interface seal member adapted for establishing a fluid tight seal about the surgical object. The seal assembly is adapted for selective movement within the pocket about multiple axes in response to manipulation of the surgical object.

Claims

1. A surgical access apparatus, which comprises:

an access member defining a longitudinal axis and having a longitudinal passageway for reception and passage of a surgical object; and

an access housing mountable to the access member, the access housing including a diaphragm mounted thereto, the diaphragm adapted for rotational movement about the longitudinal axis relative to the access housing, the diaphragm defining at least one internal pocket and having a seal assembly disposed within the internal pocket, the seal assembly having an interface seal member adapted for establishing a fluid tight seal about the surgical object, the seal assembly adapted for selective movement within the pocket about multiple axes in response to manipulation of the surgical object.

2. The surgical access apparatus according to claim 1 wherein the diaphragm includes a plurality of pockets, each pocket having a seal assembly and associated interface seal member disposed therein.

3. The surgical access apparatus according to claim 2 wherein each seal assembly includes a zero closure valve adapted to open to permit passage of the surgical object and close in the absence of the surgical object.

4. The surgical access apparatus according to claim 2 wherein each seal assembly includes a gimbal mount, each gimbal mount adapted to cooperate with internal surfaces defining a respective pocket to permit articulation of the seal assembly.

5. The surgical access apparatus according to claim 4 further comprising a low friction material associated with each pocket to facilitate rotation of a respective seal assembly.

6. The surgical access apparatus according to claim 1 further comprising a low friction material associated with the access housing to facilitate rotation of the diaphragm.

7. The surgical access apparatus according to claim 1 wherein the access housing is adapted for releasable coupling to the access member.

8. The surgical access apparatus according to claim 1 wherein the access member includes sleeve dimensioned for positioning within a tract defined within tissue.

9. The surgical access apparatus according to claim 8 wherein the sleeve is substantially flexible.

10. The surgical access apparatus according to claim 9 including proximal and distal rings associated with the sleeve for respectively engaging tissue on opposed sides of the tissue tract, at least the distal ring being deformable to permit passage through the tissue tract.

11. The surgical access apparatus according to claim 10 wherein the distal ring is selectively inflatable to expand from a non-inflated configuration to facilitate insertion of the distal ring into the operating cavity to an expanded configuration to secure the distal ring relative to the tissue.

12. The surgical access apparatus according to claim 11 wherein the proximal ring is selectively inflatable to expand from a non-inflated configuration to an expanded configuration to facilitate securement of the proximal ring relative to the tissue.

13. The surgical access assembly according to claim 11 wherein the flexible sleeve is selectively inflatable and acts as a conduit for conveying expansion gases between the proximal and distal rings.

14. The surgical access assembly according to claim 10 wherein the proximal ring includes at least one interface which is configured to mechanically engage and releasably secure the access housing to the access member.
