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 seal assembly for use with a surgical access apparatus, the seal assembly comprising:

a housing;

a diaphragm rotatably secured within the housing, the diaphragm including at least one pocket defining a cavity, wherein an entirety of the diaphragm is rotatably secured within the housing; and

a seal disposed within the cavity, the seal including an inner seal member configured as a zero closure valve adapted to open to permit passage of a surgical object, and to close absent a surgical object, the seal and the cavity including corresponding arcuate surfaces configured and dimensioned for cooperative engagement to facilitate selective articulation of the seal within the pocket about a plurality of axes.

2. The seal assembly of claim 1, wherein the seal is configured and dimensioned to establish a fluid tight seal with a surgical object upon insertion.

3. The seal assembly of claim 1, wherein the at least one pocket includes a plurality of pockets, each of the plurality of pockets defining a cavity accommodating a seal, each seal and each cavity including corresponding arcuate surfaces configured and dimensioned for cooperative engagement to facilitate selective articulation of each seal about a plurality of axes.

4. The seal assembly of claim 3, wherein each seal is configured and dimensioned to establish a fluid tight seal with a surgical object upon insertion.

5. The seal assembly of claim 4, wherein each seal includes a zero closure valve adapted to open to permit passage of a surgical object, and close absent a surgical object.

6. The seal assembly of claim 1 further comprising a low friction material associated with the pocket to facilitate articulation of the seal.

7. The seal assembly of claim 1, wherein the diaphragm includes proximal and distal surfaces, the diaphragm being secured to the housing such that the proximal surface of the diaphragm is fixedly positioned along a longitudinal axis extending through a center of the housing, whereby the proximal surface of the diaphragm remains in a substantially constant axial location during use of the diaphragm.

8. The seal assembly of claim 1, wherein the diaphragm is configured to rotatably engage an inner periphery of the housing.

9. The seal assembly of claim 8, wherein the diaphragm includes an outer periphery with a first structure, and the inner periphery of the housing includes a second structure, the first and second structures having corresponding configurations to facilitate rotation of the diaphragm in relation to the housing.

10. A surgical access apparatus, comprising:

a housing;

an access member extending distally from the housing along a longitudinal axis; and

a diaphragm rotatably mounted within the housing, the diaphragm including;

at least one pocket defining a cavity, wherein an entirety of the diaphragm is rotatably secured within the housing;

a seal disposed within the cavity, the seal and the cavity including corresponding arcuate surfaces configured and dimensioned for cooperative engagement to facilitate selective articulation of the seal about a plurality of axes; and

an inner seal member configured as a zero closure valve adapted to open to permit passage of a surgical object, and close absent a surgical object.

11. The surgical access apparatus of claim 10, wherein the diaphragm rotatably engages an inner periphery of the housing.

12. The surgical access apparatus of claim 10, wherein the diaphragm has proximal and distal surfaces, the diaphragm being secured to the housing such that the proximal surface of the diaphragm is fixedly positioned along the longitudinal axis, whereby the proximal surface of the diaphragm remains in a substantially constant axial location during use of the surgical access apparatus.

13. The surgical access apparatus of claim 10, wherein the at least one pocket includes a plurality of pockets, each of the plurality of pockets defining a cavity accommodating a seal, each seal and each cavity including corresponding arcuate surfaces configured and dimensioned for cooperative engagement to facilitate selective articulation of each seal about a plurality of axes.

14. The surgical access apparatus of claim 10 further comprising a low friction material associated with the at least one pocket to facilitate articulation of the seal.
