1. A method of providing access to an internal surgical site, comprising:

  • positioning an access port within an opening in tissue, the access port including at least one lumen extending therethrough;

    inserting a first arm through one of the lumens of the access port such that a proximal portion of the first arm is positioned externally of the internal surgical site and such that a distal portion of the first arm is positioned within the internal surgical site, the first arm including a passageway extending therethrough, first and second articulation assemblies coupled to the proximal portion thereof, and first and second articulatable segments positioned along the distal portion thereof;

    inserting a first surgical instrument through the passageway of the first arm such that an end effector assembly thereof extends distally from the first arm and such that a handle of the first surgical instrument extends proximally from the first arm; and

    manipulating a lever of the first articulation assembly of the first arm to articulate the first articulatable segment of the first arm independent of the second articulation assembly of the first arm to position the end effector assembly of the first surgical instrument for performing a surgical task within the internal surgical site.
