Methods and devices are provided for accessing a body cavity. In one embodiment, a surgical access device is provided that includes a housing having at least one access or sealing port for receiving a surgical instrument, and a retractor removably coupled to the housing and having a working channel configured to extend into a body cavity. The housing can include releasably matable upper and lower portions, with the upper portion being configured to freely rotate 360° relative to the lower portion and to the retractor when the housing is mated thereto.

1. A surgical device, comprising: a refractor configured to be positioned in an opening in tissue such that an instrument inserted into a working channel extending through the retractor can pass through the opening in the tissue and into a body cavity underlying the tissue; anda housing removably coupled to the retractor and having a plurality of sealing ports in communication with the working channel in the retractor, each of the sealing ports having a sealing element disposed therein, the housing including a distal base removably coupled to the retractor, and a proximal cap removably coupled to the distal base so as to form a fluid tight seal, the proximal cap being freely rotatable 360° relative to the distal base and the retractor when the proximal cap is removably coupled to the distal base. 2. The device of claim 1, wherein when the proximal cap is removably coupled to the distal base, the proximal cap is freely rotatable 360° clockwise and counterclockwise relative to the distal base and the retractor. 3. The device of claim 1, wherein the proximal cap is removably coupled to the distal base by at least one living hinge formed on one of the proximal cap and the distal base. 4. The device of claim 3, wherein the at least one living hinge is formed on an internal surface of the one of the proximal cap and the distal base and extends radially inward from the internal surface. 5. The device of claim 3, wherein one of the proximal cap and the distal base has a track formed therein, the at least one living hinge being configured to move within the track when the proximal cap is freely rotated 360° relative to the distal base and the retractor when the proximal cap is removably coupled to the distal base. 6. The device of claim 5, wherein the at least one living hinge is formed on an internal surface of the one of the proximal cap and the distal base, and the track is formed in an internal surface of another of the proximal cap and the distal base. 7. The device of claim 1, wherein the proximal cap is removably coupled to the distal base by a threaded engagement. 8. The device of claim 1, wherein when the proximal cap is removably coupled to the distal base, the sealing ports as a unit are freely rotatable 360° relative to the distal base and the retractor. 9. The device of claim 1, further comprising a sealing member positioned between the distal base and the proximal cap when the distal base is removably coupled to the retractor and the proximal cap is removably coupled to the distal base, the sealing member providing the fluid tight seal. 10. The device of claim 9, wherein the sealing member comprises an o-ring. 11. The device of claim 1, wherein the proximal cap includes a mating element, and the distal base includes a mating feature, the mating element being selectively releasable from the mating feature so as to remove the proximal cap from the distal base, and the mating element being selectively attachable to the mating feature so as to removably couple the proximal cap to the distal base. 12. A surgical device, comprising: a refractor configured to be positioned in an opening in tissue such that an instrument inserted into a working channel extending through the retractor can pass through the opening in the tissue and into a body cavity underlying the tissue; anda housing configured to removably couple to the retractor, the housing having a plurality of sealing ports in communication with the working channel in the refractor, each of the sealing ports having a sealing element disposed therein, the housing including a distal base and a proximal cap, the distal base being configured to removably couple to the retractor and including a mating feature, and the proximal cap being configured to removably couple to the distal base and including a mating element configured to releasably mate to the mating feature, wherein when the mating feature is mated to the mating element, the proximal cap is releasably fixed to the distal base and the proximal cap is freely rotatable 360° relative to the distal base and the refractor. 13. The device of claim 12, wherein a fluid tight seal is formed between the proximal cap and the distal base when the proximal cap and the distal base are removably coupled together such that the proximal cap can freely rotate 360° relative to the distal base without release of the fluid tight seal. 14. The device of claim 12, wherein when the mating feature is mated to the mating element, the proximal cap is freely rotatable 360° clockwise and counterclockwise relative to the distal base and the retractor. 15. The device of claim 12, wherein when the mating feature is mated to the mating element, the proximal cap is configured to be released from the distal base by disengagement of the mating feature and the mating element. 16. The device of claim 12, wherein when the mating feature is mated to the mating element, the proximal cap is freely rotatable 360° relative to the distal base in a substantially fixed plane substantially perpendicular to a longitudinal axis of the working channel. 17. The device of claim 12, wherein at least one of the mating element and the mating feature comprises at least one living hinge. 18. The device of claim 12, wherein the mating feature and the mating element comprises complementary threads such that the proximal cap is configured to removably couple to the distal base by a threaded engagement.
