【発明の実施の形態】以下、実施の形態を示す図面に基
づき、本発明の腱固定部材を詳説する。BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the tendon fixing member of the present invention will be described in detail with reference to the drawings showing an embodiment.

る。FIG. 1 is a cross-sectional view of a tendon fixing member showing an embodiment of the present invention. The tendon fixing member indicated by reference numeral 1 is made of apatite, and is used for fixing a broken tendon 2 to a bone 3. A reversion prevention mechanism 4 for locking the tendon 2 is provided on the inner surface of the hole 5 formed in the axial direction.

を防止できるように構成している。The reversion prevention mechanism 4 is formed with an inner surface shape of the through hole 5, and specifically, the inner surface shape is formed into a truncated cone type space 41. That is, a frusto-conical hole 5 whose diameter is reduced from the entrance side A to the back side B
The tendon 2 is inserted into the
By locking 21 the tendon 2 can be prevented from coming off in the backward direction.

が好ましい。The inner surface of the hole 5 forming the reversion preventing mechanism 4 is made of dense apatite so as to ensure sufficient strength to stably lock the tendon 2 and the bone 3 of the tendon fixing member 1. It is preferable that the portion that comes into contact with, that is, the side surface 7 and the end surface 8 on the side where the tendon 2 is inserted be formed of porous apatite so that replacement with bone can be performed quickly.

密質アパタイト）は、気孔率が０〜20％のものであり、
多孔質体（多孔質アパタイト）は、気孔率が60〜80％で
ある。By the way, in the present invention, apatite is defined to mean a calcium phosphate-based sintered body in a broad sense. Among them, hydroxyapatite is the most preferable material because of its excellent strength. The dense body (dense apatite) has a porosity of 0 to 20%,
The porous body (porous apatite) has a porosity of 60 to 80%.

体の気孔率が60％未満になると、骨に置換される時間が
長くかかり過ぎる。気孔率が80％を越えると、強度が低
下するため、損壊する虞がある。When the porosity of the dense body exceeds 20%, the strength is significantly deteriorated, which is not preferable. Further, if the porosity of the porous body is less than 60%, it takes too long time to be replaced with bone. If the porosity exceeds 80%, the strength is reduced and there is a risk of damage.

所定の厚みの有る係止壁部12を残して、その反対側か
ら、腱固定部材１を挿入するための挿入孔13をあける。In the example of the treatment shown in FIG. 1, first, a small hole 11 is formed in the bone 3 of the portion where the tendon 2 is to be fixed so that the tendon 2 can be inserted therethrough. Then, the locking wall 12 having a predetermined thickness is left around the small hole 11, and an insertion hole 13 for inserting the tendon fixing member 1 is opened from the opposite side.

２の挿入が容易である。Next, the tendon fixing member 1 is inserted into the insertion hole 13 and the tendon 2 is drawn into the hole 5 of the tendon fixing member 1 through the small hole 11 so that the end 21 of the tendon 2 is reduced to the reduced diameter end 6. Pull out from and lock it in a state where it does not come back. In addition, since the hole 5 is formed in a tapered shape (reducing the diameter toward the inner side B), the tendon 2 can be easily inserted.

よい。The end of the tendon 2 pulled out from its reduced diameter end 6.
The 21 is locked as it is, but if necessary, it may be hit with a tack or the like to make it more difficult to pull out. The porosity of the reversion prevention mechanism 4 is preferably 0 to 20%, but when strength is required, the porosity may be set to near 0%.

ておくことができる。The tendon fixing member 1 constructed as described above is
Since it is made of apatite, it has a good affinity with living tissue, has no internal discomfort, and the bone replacement is promptly performed between the side surface 7 and the end surface 8 that come into contact with the bone 3, and finally the bone is integrated with the bone. Therefore, the tendon 2 can be stably locked for a long period of time.

毒として作用する）を懸念するに及ばず、耐久性が良好
であり、しかも、再手術の必要もない。 Further, since a metal material such as a metal bolt or a wire is not used, there is no fear of deterioration or toxicity (the elution of metal ions acts as bone cell poison), the durability is good, and moreover, There is no need for re-operation .
