Abstract:
Apparatus for the production of endochondral or osteochondral bores comprising:a hollow cylindrical sleeve formed about an axis having a proximal end and a distal end;a cutting edge defined by the distal end of the hollow cylindrical sleeve;a constant inner diameter formed in the hollow cylindrical sleeve about the axis in the region of the distal end, the constant inner diameter beginning at the cutting edge of the distal end and extending into the hollow cylindrical sleeve;a borer having a proximal end for rotation from within the hollow cylindrical sleeve;the borer having a distal end defining a substantially flat cutting surface normal to the axis within the constant inner diameter; and,the borer having displacement along the axis to enable rotation and displacement of the borer relative to the cutting edge inside and outside the constant inner diameter.
