<p>A dilator (1) for reconstructing an anterior cruciate ligament, comprising a tip part (4) having two through holes (2) and (3) arranged parallel with each other, a body part (5), and a rear end part (8) having two through holes (6) and (7) arranged coaxially with the two through holes (2) and (3). The tip part (4) and the body part (5) are formed in uniform generally elongated shapes in cross section longer in the arranged direction of the through holes (2) and (3) so that a flat tunnel can be formed by striking the instrument from the rear end part (8) thereof to drive the tip part (4) and the body part (5) into an articular bone part. Thus, the anterior cruciate ligament can be reconstructed to a more tough ligament similar to a normal one in a shorter time.</p> |
