摘要： A surgical bone reamer 10 includes a rotatable, elongated shank 12 having a proximal end 14, a distal end 16 and a longitudinal axis, and a reaming head 18 mounted on the distal end 16. A plurality of equally spaced walls 34 are radially disposed on the reaming head around the longitudinal axis, and tip edges 40 for penetrating bone are defined on the radial walls 34 to be disposed angularly with the longitudinal axis. Reaming edges 42 joined to the tip edges 40 extend longitudinally from the tip edges 40 in the proximal direction parallel to and an equal radial distance from the longitudinal axis for reaming a cylindrical tunnel when the reaming head 18 is rotated in bone. Tapered flutes 48 disposed angularly between the tip edges 40 and the radial walls 34 permit bone to be evacuated through the reaming head 18 when forming a tunnel in bone.
