Abstract

Methods and devices are provided for providing surgical access into a body cavity. In one embodiment, a surgical access device is provided that includes a housing coupled to a retractor. The housing can be have one or more movable sealing ports for receiving surgical instruments. Each movable sealing port can include one or more sealing elements therein for sealing the port and/or forming a seal around a surgical instrument disposed therethrough. Each movable sealing port can be rotatable relative to the housing and each sealing element can be rotatable relative to the housing along a predetermined orbital path.

Claims

1. A surgical access device, comprising:

a housing having a working channel extending therethrough;

a base coupled to the housing and having first and second sealing elements, the base being configured to rotate relative to the housing, and the first and second sealing elements each being configured to receive an instrument inserted therethrough and into the working channel, and each of the first and second sealing elements being movable independent of another of the first and second sealing elements in a predetermined orbital path.

2. The device of claim 1, wherein each of the first and second sealing elements are laterally movable in a predetermined orbital path.

3. The device of claim 1, wherein the first sealing element with a surgical instrument held in a substantially fixed position therein is configured to move in a predetermined orbital path in response to movement of the second sealing element in a predetermined orbital path.

4. The device of claim 1, wherein the predetermined orbital paths of the first and second sealing elements each have a central axis that is offset from a central axis of the base.

5. The device of claim 1, wherein the base includes first and second cut-outs formed therein, and wherein perimeters of the first and second cut-outs respectively define the predetermined orbital paths of the first and second sealing elements.

6. The device of claim 1, wherein each of the first and second sealing elements is disposed within a support that is rotatably disposed within the base, each sealing element being eccentric relative to its respective support.

7. The device of claim 1, wherein each of the first and second sealing elements are configured to provide a fluid seal with no instrument inserted therethrough.

8. The device of claim 1, further comprising at least one fixed sealing element fixedly disposed within the base and configured to remain in a fixed position relative to the base.

9. The device of claim 8, wherein the first and second sealing elements and the at least one fixed sealing element are positioned radially around a central axis of the base.

10. The device of claim 8, wherein the at least one fixed sealing element is disposed in a plane offset from and parallel to a plane containing the first and second sealing elements.

11. The device of claim 8, wherein the at least one fixed sealing element comprises first and second fixed sealing elements, the first fixed sealing element being positioned below a plane of the first and second sealing elements and the second fixed sealing element being positioned above the plane containing the first and second sealing elements.

12. The device of claim 1, further comprising a side access port formed in a proximal retractor base configured to be coupled to the housing and configured to receive an instrument inserted therethrough.

13. The device of claim 12, wherein the side access port extends in a plane that is offset from a plane containing the base.

14. The device of claim 1, further comprising a flexible retractor coupled to the housing.

15. The device of claim 14, further comprising a retractor shield disposed in the flexible retractor.

16. The device of claim 14, wherein the flexible retractor is rotatably coupled to the housing.

17. A method of providing access through tissue to a body cavity, comprising:

positioning a surgical access device within an opening formed through tissue such that the surgical access device forms a working channel extending through the tissue and into a body cavity;

inserting a first surgical instrument through a first sealing element in the surgical access device and through the working channel of the surgical access device to position a distal end of the first surgical instrument within the body cavity; and

moving the first surgical instrument to cause the first sealing element to move along an orbital path from a first position, in which the first sealing element is located a first distance from a center-point of the surgical access device, to a second position, in which the first sealing element is located a second distance from the center-point of the surgical access device that is different from the first distance.

18. The method of claim 17, wherein moving the first surgical instrument causes rotation of a base of the surgical access device that is coupled to the housing, the rotation of the base causing a second sealing element in the surgical access device having a second surgical instrument inserted therethrough to move along an orbital path from a third position, in which the second sealing element is located a third distance from the center-point of the surgical access device, to a fourth position, in which the second sealing element is located a fourth distance from the center-point of the surgical access device that is different from the third distance.

19. The method of claim 17, wherein the working channel extends through a housing of the surgical access device, and wherein moving the first surgical instrument causes a base of the surgical access device that is coupled to the housing to rotate relative to the housing.
