13. A surgical system, comprising:
-
an anvil of a circular stapler; a tool introducer having a first elongate tubular portion defining a first elongate access passage extending therethrough that is sized to releasably retain at least a portion of the anvil therein; and an access port comprising a port body having a second elongate tubular portion protruding therefrom that is sized to extend into an opening into a body cavity and defining a second elongate access passage therethrough that is sized to movably support said first elongate tubular portion of said tool introducer therein; and a retention structure on said first elongate tubular portion of said tool introducer for releasably attaching the anvil thereto such that said first elongate tubular portion and the anvil may be inserted through the opening in the body cavity as a unit and a second position wherein the anvil is detachable from the first elongate tubular portion of said tool introducer. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. An access system for introducing an anvil of a circular stapler into a body cavity and for removing a specimen therefrom, said access system comprising:
-
a tool introducer having a first elongate tubular portion defining a first elongate access passage extending therethrough that is sized to releasably retain at least a portion of the anvil therein; an access port comprising a port body having a second elongate tubular portion protruding therefrom that is sized to extend into an opening into the body cavity and defines a second elongate access passage therethrough that is sized to movably support said first elongate tubular portion of said tool introducer therein; a retention structure on said first elongate tubular portion of said tool introducer for releasably attaching the anvil thereto such that said first elongate tubular portion and the anvil may be inserted through the opening in the body cavity as a unit and a second position wherein the anvil is detachable from the first elongate tubular portion of said tool introducer; and a flexible specimen bag coupled to said access port and being selectively deployable from a storage position wherein said flexible bag specimen does not obstruct said second elongate access passage in said second elongate tubular portion of said access port such that said tool introducer may slide axially within said second elongate access passage therein and a deployed position wherein a distal end portion of said flexible specimen bag may pass through said first elongate access passage in said tool introducer into the body cavity and wherein said port body comprising an annular cavity therein configured to removably support said flexible bag specimen therein without obstructing the second elongate access passage.
