る。FIG. 1 is a cross-sectional view of a tendon fixing member according to 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 torn tendon 2 to a bone 3. A back-up 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 reverse movement preventing mechanism 4 is formed to have the inner surface shape of the through-hole 5, and more specifically, the inner surface shape is formed as a truncated conical space 41. That is, a truncated conical hole 5 whose diameter is reduced from the inlet side A to the inner side B
The end of the tendon 2 is inserted into the reduced diameter end 6 of the hole 5
By locking the 21, the tendon 2 is configured to be prevented from coming off in the reverse 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 to secure the bone 3 of the tendon fixing member 1. It is preferable that the portion contacting with the side, that is, the side face 7 and the end face 8 on the side into which the tendon 2 is inserted be formed of porous apatite so that replacement with bone is 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 as a calcium phosphate-based sintered body in a broad sense. Among them, hydroxyapatite is excellent in strength and is the most preferable material. 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。[0014] If the porosity of the dense body exceeds 20%, the strength is significantly reduced, which is not preferable. On the other hand, if the porosity of the porous body is less than 60%, it takes too long to be replaced with bone. If the porosity exceeds 80%, the strength is reduced, and the porosity may be damaged.

だけの小孔11をあける。次いで、その小孔11のまわりに
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 enough to allow the tendon 2 to be inserted is made in the bone 3 where the tendon 2 is to be fixed. Next, an insertion hole 13 for inserting the tendon fixing member 1 is opened from the opposite side, leaving the locking wall portion 12 having a predetermined thickness around the small hole 11.

In addition, since the hole 5 is formed in a tapered shape (reducing the diameter toward the back side B), the insertion of the tendon 2 is easy.

21 is locked as it is, but if necessary, it may be harder to pull out by hitting a stud or the like. The porosity of the reversion preventing mechanism 4 is preferably 0 to 20%. In particular, when strength is required, the porosity may be set to near 0%.

Since it is made of apatite, it has a good affinity for living tissue, there is no sense of incongruity inside, and bone replacement is rapidly performed on the side surface 7 and the end surface 8 that come into contact with the bone 3, and finally, it is integrated with the bone. Therefore, the tendon 2 can be stably locked for a long period of time.

In this case, the inner surface shape of the hole 5 that constitutes the reversion preventing mechanism 4 is such that a plurality of truncated conical spaces 41, 42, 43, 44,.
The inner cylinder 15, which is formed so as to be continuous while becoming smaller, and which forms the reversion preventing mechanism 4, is fitted into the outer cylinder 16 to constitute the tendon fixing member 1. In other words, the diameter of the frusto-conical space 41 on the inlet side A is the largest, and the diameter decreases as it approaches the inner side B.

The structure in which the tendon 2 is locked in a multi-stage manner by 2, 43, 44,... Can further improve the effect of preventing the tendon from returning. In addition, since the length (thickness) L in the axial direction can be set large, it is suitable when a large load is applied (the locking force is dispersed in the length L direction). In this case as well, it is preferable that the end of the tendon is inserted until the part thereof comes out from the reduced diameter end 6.
