Articulating apparatus for endoscopic procedures

An endoscopic surgical device, comprising;

• a handle assembly including a handle housing and a trigger operatively connected to the handle housing, and a drive mechanism actuatable by the trigger;
• an endoscopic assembly including:
• a proximal end portion extending from the handle assembly;
• a distal end portion pivotably connected to the proximal end portion of the endoscopic assembly at a pivot point;
• and
• a rotatable inner actuation shaft extending from the handle assembly and into the distal end portion of the endoscopic assembly, the inner actuation shaft including a flexible portion extending across the pivot point, the inner actuation shaft being connected to the drive mechanism of the handle assembly such that an actuation of the trigger results in a rotation of the inner actuation shaft;
• and
• an end effector selectively connectable to the distal end portion of the endoscopic assembly and to a distal portion of the rotatable inner actuation shaft, the end effector includes:
• an outer tube having a helical thread along an inner surface thereof;
• a splined inner tube rotatably supported in the outer tube, wherein the splined inner tube is defined by a pair of opposed longitudinally extending tines and a pair of opposed longitudinally extending channels, a proximal end of the splined inner tube being configured for non-rotatable selective connection to a distal end of the rotatable inner actuation shaft when the end effector is connected to the distal end portion of the endoscopic assembly;
• and
• a plurality of surgical anchors loaded in the inner tube of the end effector, wherein each anchor includes a threaded body portion, and a head portion defining a pair of opposed radially outer threads and a pair of opposed radial recesses, wherein the pair of radial recess of each head portion receive respective tines of the inner tube and wherein the pair of opposed radially outer threads of each head portion project from the pair of opposed longitudinally extending channels of the inner tube and engage the inner helical thread of the outer tube.
