An endoscopic instrument includes a housing having shaft. The shaft includes an articulating section disposed thereon. The articulating section includes a plurality of annular stationary and rotatable links arranged in an alternating configuration therealong. Each link of the plurality of rotatable links seated within a corresponding stationary link of the plurality of stationary links to collectively define a central annulus therethrough. An end effector assembly operatively connected to a distal end of the shaft includes a pair of first and second jaw members. An articulation catheter operably disposed through the central annulus is configured to rotate the rotatable links with respect to the stationary links to articulate the shaft about the articulating section.
