【従来の技術】損傷した生体靭帯を補うべく人工靭帯あるいは自家靭帯を用いて再建する場合、それら再建靭帯の固定にはステープルが多く用いられてきた。 2. Description of the Related Art When reconstruction using an artificial ligament or autologous ligament to compensate for the damaged biological ligament, the fixing of their reconstruction ligament has been used many staples. 従来のステープルの構造は図12に示すように、門形形状に形成され、水平杆部と脚杆から成り、水平杆部の下面に突起が突設されたり、脚杆の外面に山形形状の突起が突設された構造を持つものもある。 Structure of a conventional staple as shown in FIG. 12, is formed in a gate shape, made horizontal rod part and Ashi杆, or protrusions protruding from the lower surface of the horizontal rod portions, chevron shape to the outer surface of Ashi杆some of which having a protrusion projecting structure. そして、上記したステープルは再建靭帯の端部で当該ステープルを骨に打ち込んで、水平杆部と骨の表面とで再建靭帯を挟みつけて固定するようになっている。 Then, the staples described above by implanting the staples in the bone at the end of the reconstruction ligament, so as to fix clamped reconstruction ligament in the horizontal rod portion and the bone surface.

【0003】 [0003]

【発明が解決しようとする課題】しかしながら、上記した従来のステープルはステープルの水平杆部と骨表面との圧迫力で再建靭帯を固定するため、その固定力が弱い。 [SUMMARY OF THE INVENTION However, the conventional staple described above to secure the reconstruction ligament in compression force to the staple of the horizontal rod portion and the bone surface, the fixing force is weak. ステープルの固定力を高めるために図13の如く従来のステープルを2個使用し、再建靭帯をまず1本のステープルで固定し再建靭帯を折り返し、最初のステープルに近接して2本目のステープルを打ち込むダブルステイプリング法があった。 A conventional staple as shown in FIG. 13 uses two to increase the fixing force of the staple, folding a fixed reconstruction ligament is first one staple reconstruction ligaments, implanted two second staples close to the first staple there was a double stapling technique. この方法はステープル同士を近接しなければ、その固定力の増大効果を発揮できず、反面ステープル同士が近接すればステープルを骨に保持するステープルの両脚杆部分が近接するため、骨への固定力が弱くなる欠点をもつ。 If this method is required to close the staples together, that can not exhibit the effect of increasing the fixed force, contrary because if staples each other proximity staple legs rod portions component that holds the staples in the bone adjacent, the fixing force to the bone It has the disadvantage that is weakened. これはステープルの初期固定力が弱くなるだけでなく、長期の骨への保持力の低下や、ステープル固定部の痛みなどの問題点を生じる。 This not only the initial fixing force of the staple is weakened, lowering of the holding force to the long bone, resulting in problems such as pain stapling portion.

【0004】かといって、2個のステープルを間隔をおいて打ち込めば、再建靭帯の固定力は弱くなる。 [0004] or to say, if Uchikome two staples at intervals, fixing force of reconstruction ligament is weakened. そのために、2個のステープルを互いに角度を付けて打ち込むことも考えられるが、従来のステープルは傾斜をつけて打ち込むと、ステープルの水平杆部の下面が骨と密着せず隙間が空くため、靭帯の固定力が低下する欠点があった。 Therefore, it is conceivable to implant at an angle with two staples each other, the conventional staple implanting beveled, since the lower surface of the staple of the horizontal rod portion becomes free gap without contact with the bone, ligament there is a disadvantage that fixing force is reduced. 骨が平面状でなく球面状の時も、ステープルの水平杆部下面が骨と隙間を生じ靭帯の固定力が低下する欠点があった。 Even when the bone is spherical rather than flat, horizontal rod portions the lower surface of the staple fixing force ligaments resulting bone and gap is a drawback to decrease. 従来、ステープルの両脚杆に山形形状突起を有し、骨への固定力の増大を図るものもあったが、長期的な骨への固着力を得るものではなかった。 Conventionally, it has a chevron shape protruding to both legs rod staples but was also aims to increase the fixing force to the bone, did not obtain the fixing strength to the long-term bone.

【0005】本発明は上記した従来の技術が有する問題点に鑑みてなされたもので、その目的とするところは、 [0005] The present invention has been made in view of the problem prior art described above has, and it is an object
再建靭帯を強力に固定し、さらに長期に亘って維持することができるステープルを提供することにある。 Reconstruction ligament strongly fixed, to provide a staple which can be maintained over a further long term.
