(57) [Abstract] [Purpose] To provide a jig which is excellent in compatibility with a living body when fixing a fractured part and does not cause wrapping of meat. [Structure] A bone fixing jig in which a coating layer of Al 2 O 3 is formed on the surface of high-purity titanium processed into a fixing jig for a fractured part.
Description
【０００１】[0001]
この考案は、骨の固定治具に関するものである。 The present invention relates to a bone fixing jig.
【０００２】[0002]
骨折した骨を外部固定して安定する外固定法又は副子固定法が知られている。 例えば、特開昭６２−６６８５０号公報には、図２に示すようなピンおよびピン のクランプが記載されている。図においてピン１．１は、骨Ｂの骨折部Ｆを挟ん で剛体棒２およびピンクランプ３で骨を固定して安定化する。ピン１はステンレ ス、チタンあるいは黒鉛の混合物が用いられている。一方チタンは、生体適合性 に優れていることから、骨折部の固定具にＴｉＮを被覆する開示がある（特開平 ２−１９８５５０号公報）。 An external fixation method or a splint fixation method for externally fixing and stabilizing a fractured bone is known. For example, Japanese Patent Laid-Open No. 62-66850 discloses a pin and a pin clamp as shown in FIG. In the figure, the pin 1.1 stabilizes the bone by fixing the bone with the rigid rod 2 and the pin clamp 3 while sandwiching the fractured portion F of the bone B. The pin 1 is made of a mixture of stainless steel, titanium or graphite. On the other hand, since titanium is excellent in biocompatibility, there is a disclosure that TiN is coated on a fixture for a fractured part (Japanese Patent Laid-Open No. 2-198550).
【０００３】[0003]
一般にステンレス鋼はＣｒを１２〜３２％含み、したがってステンレス鋼から なるピンを用いるときはＣｒによって生体が侵される恐れがある。又Ｔｉは、生 体との適合性に優れているので、Ｔｉのピンを固定したい骨折部に使用するとき 、ピン自体に骨折部近傍の筋肉が巻き付き、骨折部の固定後ピンを除去する際に 困難を伴う。 Generally, stainless steel contains 12 to 32% of Cr, and therefore, when a pin made of stainless steel is used, Cr may invade a living body. Also, since Ti has excellent compatibility with the living body, when the Ti pin is used in a fractured part where fixation is desired, when the muscle around the fractured part wraps around the pin itself and the pin is removed after fixation of the fractured part. With difficulty.
【０００４】 本考案は、生体との適合性に優れ、かつ生体からのピンの除去が容易な骨の固 定治具を提供するものである。The present invention provides a bone fixing jig that has excellent compatibility with a living body and that allows easy removal of the pin from the living body.
【０００５】[0005]
本考案は、骨折部の固定治具に加工された高純度チタン材の表面にＡｌ2 Ｏ3 の被膜を形成した骨の固定治具である。The present invention is a bone fixing jig in which a coating of Al 2 O 3 is formed on the surface of a high-purity titanium material processed into a fixing jig for a fractured part.
【０００６】[0006]
【作用】 人の骨折部の皮膚、肉、骨を突き通したピンは約６か月後に骨折部から引き抜 き除去されるが、本考案のピンは高純度チタンからなり、Ａｌ2 Ｏ3 の被膜層を 有するので、肉の巻き付きを生じることがない。したがって生体からピンを容易 に除去することができる。The skin of the fracture of the [action] people, meat, but pins piercing the bone is removed-out pull disconnect from the fracture after about 6 months, the pin of the present invention consists of high-purity titanium, Al 2 O 3 Since it has a coating layer of, there is no wrapping of meat. Therefore, the pin can be easily removed from the living body.
【０００７】[0007]
図１は本考案のピンの側面図である。図において高純度チタン製のピン１を示 す。純チタンはＪＩＳ規格３種によると表１の通りである。 FIG. 1 is a side view of the pin of the present invention. In the figure, pin 1 made of high-purity titanium is shown. Pure titanium is as shown in Table 1 according to JIS standard 3 types.
【表１】 [Table 1]
【０００８】 ピン１は通常φ３．５〜５．０mm、長さ１２５〜３００mmが用いられ、螺旋ネ ジ６が予め切削加工され、先細状にテーパー加工されている。ピン１のＡｌ2 Ｏ3 被膜層形成の方法は特に限定されないが、真空槽を例えば０．０００４mmHg程 度に排気してＡｌの真空蒸着を行った。Ａｌ蒸着後ＣＯ2 雰囲気で加熱（３００ ℃以下）するとＡｌ2 Ｏ3 被膜厚み０．１μm が得られた。５はクランプ嵌合溝 である。Ａｌ2 Ｏ3 被膜生成は勿論生体に埋め込まれる部分で十分である。 このＡｌ2 Ｏ3 被膜層を有するピンは、人の骨折部を固定後６か月を経て除去 するとき全く困難性はなかった。The pin 1 usually has a diameter of 3.5 to 5.0 mm and a length of 125 to 300 mm, and the spiral screw 6 is previously cut and tapered to a tapered shape. The method for forming the Al 2 O 3 coating layer on the pin 1 is not particularly limited, but the vacuum chamber was evacuated to about 0.0004 mmHg and the vacuum deposition of Al was performed. When Al was vapor-deposited and heated in a CO 2 atmosphere (300 ° C. or lower), an Al 2 O 3 coating thickness of 0.1 μm was obtained. 5 is a clamp fitting groove. The formation of the Al 2 O 3 film is, of course, sufficient for the portion to be embedded in the living body. The pin having the Al 2 O 3 coating layer had no difficulty when the human fracture was removed 6 months after fixation.
【０００９】 以上本考案を骨折部を固定するピンについて説明したが、勿論、患部に貫通し て骨を固定後再び引き抜くようなスクリュー、釘についても適用することができ る。Although the present invention has been described above with respect to a pin for fixing a fractured part, it is of course applicable to a screw or a nail that penetrates an affected part, fixes the bone, and then pulls it out again.
【００１０】[0010]
本考案のピンは高純度Ｔｉであり、かつピンの表面にＡｌ2 Ｏ3 被膜層を有す るので骨折部を固定しても、生体内において肉の巻き付きを生じることがない。 しかもＴｉは生体との適応性に優れているので、骨折部の固定に適している。Since the pin of the present invention is made of high-purity Ti and has an Al 2 O 3 coating layer on the surface of the pin, even if the fractured part is fixed, wrapping of meat does not occur in the living body. Moreover, since Ti has excellent adaptability to a living body, it is suitable for fixing a fractured part.
