1. An endoscopic surgical access device for detachably engaging an insertion section of an endoscope at or near a distal end portion of said insertion section, comprising:

  • a stationary first body having a distal end, a proximal end, and a holding member, the holding member including at least one insert clipping projection defining an insert receiving cavity and having a first longitudinal axis and an insert abutting face;

    an articulatable second body having a proximal opening and a distal opening, the openings defining an accessory channel member passageway having a second longitudinal axis, the distal opening of a distal end of the second body oriented toward a space exterior to the first body distal end; and

    a coupler joining the second body to the first body, the coupler having a mounting member comprising an axis and an articulation link member comprising an axis, the mounting member and articulation link member configured to articulatively couple the second body to the first body about a common single point of articulation defined by the mounting member axis intersecting with the articulation link member axis,wherein the second body longitudinal axis is capable of articulating relative to the first body longitudinal axis and the common single point of articulation such that the second body has at least two degrees of rotational freedom about the common single point of articulation,wherein the articulating second body is capable of moving in at least two of x, y, and z coordinates about the single point of articulation relative to the first body longitudinal axis.
