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; and
a 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.

Abstract
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.

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; and a 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. - View Dependent Claims (13, 14, 15, 16, 17, 18)
