1. An endoscopic sinus surgery device comprising:
a lever operably;
an outer sheath operably coupled with the lever, the outer sheath including:
a distal end;
a proximal end;
a surgical elevator disposed at the distal end of the outer sheath, the surgical elevator having a surgical elevator edge; and
a hypotube extending along a length of the outer sheath to the distal end of the outer sheath, the hypotube having a hypotube access hole; and
a shaver blade assembly, the shaver blade assembly including:
an outer shaft partially disposed within the outer sheath;
an outer blade disposed at a distal end of the outer shaft;
an inner blade disposed within the outer blade, wherein the outer blade and the inner blade cooperate with each other to create a resection surface;
a stop disposed at the distal end of the outer shaft; and
an outer shaft access hole in a bottom surface of the outer shaft, the outer shaft access hole being proximate to the outer blade and the inner blade, wherein the lever is configured to move between a first position and a second position such that the outer sheath moves relative to the outer shaft, wherein, in the first position:
the surgical elevator edge abuts the outer shaft stop;
the outer shaft access hole aligns with the hypotube access hole; and
the distal end of the outer shaft extends further than the surgical elevator edge;
and wherein, in the second position, the surgical elevator edge is spaced apart from the outer shaft stop.
