1. A device for cutting bone tissue, comprising:
a body defining a channel extending longitudinally at least partially from a proximal end of the body to a distal end of the body, the distal end of the body defining a truncated conical surface and a slot defined partially through the distal end, the slot being in perpendicular relation relative to the channel;
a rod slidably engaged within the channel of the body;
a blade positioned along the rod and captured within the slot of the body;
a head portion defined along the rod for receiving a blunt force to drive the rod in a first direction along channel, thereby moving the blade in the first direction relative to the body, the head portion having a flat striking surface, wherein a direction of elongation of the blunt force is normal to a plane defined by the flat striking surface;
a quick quill stop along the rod between the head portion and the body, the quick quill stop having a distal surface that contacts a proximal surface of the body when the rod is driven in the first direction relative to the body to limit a travel distance of the blade relative to the body which corresponds within a cutting depth of the blade into a target structure; and
wherein the quick quill stop includes threads engaged to respective threads defined along the rod; and
wherein the quick quill stop includes a button that releases the threads of the quick quill stop from the respective threads of the rod to accommodate free sliding movement of the quick quill stop along the rod.
