Instrument for reconstructing ligament and method of reconstructing ligament

摘要

A dilator (1) for reconstructing an anterior cruciate ligament, comprising a tip part (4) having two through-holes (2) and (3) arranged in juxtaposition and parallel with each other, a body part (5), and a rear end part (8) having two through-holes (6) and (7) arranged in juxtaposition and coaxially with the two through-holes (2) and (3), respectively. 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.
