1. An endoscopic treatment system for use with an endoscope having a proximal end and a distal end and a longitudinal axis extending therebetween, the endoscopic treatment system comprising:
a distal cap assembly having an end effector rotatable on an axis between open and closed positions, the end effector having a free end;
a transmission assembly having proximal and distal ends, the distal end operably coupled to the end effector such that displacement of at least a portion of the transmission assembly rotates the end effector between the open and closed positions;
a proximal handle assembly coupled to the transmission assembly and adapted to effect the displacement of the at least a portion of the transmission assembly to rotate the end effector;
first and second lumens extending along and external to the endoscope and the transmission assembly and from the cap assembly to the proximal handle assembly and configured for receiving instruments therethrough, the first lumen fixed to the cap assembly at a position in alignment with the free end of the end effector, and the second lumen extending along the endoscope between the transmission assembly and the first lumen and fixed to the cap assembly at a position between the first lumen and the axis on which the end effector rotates;
a peripheral engagement structure adapted to be positioned about greater than 180° of a circumference of the distal end of the endoscope, the peripheral engagement structure in an abutting relationship with a proximal end of the cap assembly; and
a plurality of spaced apart ancillary clips, the plurality of spaced apart ancillary clips adapted to retain the transmission assembly and the first and second lumens relative to the endoscope.
