摘要：
Methods and devices are provided for providing surgical access into a body cavity. In general, the methods and devices allow a surgical access device to be securely positioned within an opening in tissue to provide access to a body cavity underlying the tissue. An actuator can be rotatably disposed on or in a housing of a surgical access device such that rotation of the actuator relative to the housing is effective to move a cannula of the surgical access device between an insertion configuration in which the cannula has a reduced profile enabling it to easily be inserted into a tissue opening, and an expanded profile enabling it to form an anchor against and/or within the tissue opening.
