Devices and methods for detachably engaging an insertion section of an endoscope and selectively articulating an endoscopic surgical access channel are provided. A device comprises an articulating main body having a stationary first body, an articulatable second body, and coupler having a mounting member and an articulation link member configured to articulatively couple the second body to the first body. The stationary first body has a distal end, a proximal end, and a first longitudinal axis. The articulatable second body has a proximal opening and a distal opening defining an accessory channel member passageway, the distal opening having a second longitudinal axis oriented toward a space exterior to the first body distal end, wherein the second body longitudinal axis is capable of articulating relative to the first body longitudinal axis. The devices and methods, as taught herein, provide control over the position and/or orientation of a diagnostic, monitoring, scope, sewing device, cutting device, suturing device, forceps, grabbing device, instrument, or other tool within the visual field beyond the distal opening of the endoscope.
What is claimed is: 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 inclu
