Methods and devices are provided to improve access to a surgical site during surgical procedures. In one exemplary embodiment a surgical access device is provided having a cannula, a cannula base, and a retractor. The cannula base is configured to couple both to the retractor and the cannula to provide access to a surgical site. The cannula can be removably and replaceably coupled to the cannula base. Optionally, the cannula base can be removably and replaceably coupled to the retractor. As desired, the cannula can be decoupled from the cannula base, which can allow for an object to be removed from the surgical site and/or for the cannula, or another cannula to be attached to the cannula base that remains in place to maintain access to the surgical site. Exemplary methods for accessing a surgical site are also provided.
