Description
【発明の詳細な説明】 本発明は人工腱の改良に関するものである。[Detailed description of the invention] The present invention relates to improvements in artificial tendons.
従来の人工腱は腟として体内で力の作用をするものでな
く、人工腱の周囲に鍵鞘を作成するためのものである。Conventional artificial tendons are not used to exert force within the body as a vagina, but are used to create a key sheath around the artificial tendon.
従来の人工腱は２種あり、その−フはシリコンロンドと
いわれるもので、固形シリコンのみよりなり、単に鍵鞘
を作成するためだけのものである。There are two types of conventional artificial tendons, one of which is called a silicone rond, which is made only of solid silicon and is used simply to create a key sheath.
他の＝９はハンターロンドといわれるもので、ダクロン
（アメリカデュポン社製の飽和ポリエステルの高分子繊
維の商品名）の芯の入った固形シリコンである。The other = 9 is called Hunter Rond, and is solid silicone with a core of Dacron (trade name of saturated polyester polymer fiber manufactured by DuPont of America).
これは、力学的強度もあるが、固くて可撓性が乏しく、
また生体との癒着も弱く１人工腱としての使用は不十分
で、これも誰鞘作成をこのみ使用されておる。その他現
在研究されているものに、牛の膠質をとりだして作成し
たコラーゲン人工社があるが、ｌ１ｌｌに変化するのに
時間がかかり未だ実用化されていない。Although it has mechanical strength, it is hard and has poor flexibility.
In addition, the adhesion with the living body is weak, and its use as an artificial tendon is inadequate, so it is only used to create sheaths. Another product currently being researched is Collagen Artificial Co., Ltd., which is made from cow colloid, but it takes a long time to transform into l1ll, so it has not yet been put to practical use.
本発明の人工腱は体内に挿入する人工腱そのものが人工
腱として働くのではなく、筋肉との移行部、骨との移行
部に生体側から膠原繊維が進入して結合し、ｍ部分にも
それらの繊維の進入が起き。In the artificial tendon of the present invention, the artificial tendon itself that is inserted into the body does not function as an artificial tendon, but collagen fibers enter from the living body side and connect to the transition area with muscle and bone, and also in the m part. The entry of those fibers occurs.
人工腱の内部および表面を自家組織で包埋するものであ
る。The interior and surface of the artificial tendon are embedded with autologous tissue.
本発明の人工腱の構造は第１図の実施例に示すように、
複数本のダクロン糸１を編むことにより人工腱の体部２
を柔軟性のある可撓体とし、その可撓体２の空隙に膠原
繊維の進入を容易をこしている。第２図は前腕中央より
指先に人工腱を挿入して、指先と腕筋内部に人工腱を取
付けた実施例を示す。The structure of the artificial tendon of the present invention is as shown in the embodiment of FIG.
The body part 2 of the artificial tendon is created by weaving multiple Dacron threads 1.
is made into a flexible body, and collagen fibers can easily enter into the voids of the flexible body 2. FIG. 2 shows an example in which an artificial tendon is inserted into the fingertip from the center of the forearm and attached to the fingertip and inside the arm muscle.
人工腱の筋肉との移行部は力学的に負荷が強くかかるた
め２強い結合が必要であるので２本発明の人工腱ではそ
の部分にＩＶ形網状性３を附加して。Since the transition area between the artificial tendon and the muscle is subject to a strong mechanical load, a strong connection is required. Therefore, in the artificial tendon of the present invention, an IV-shaped reticular structure 3 is added to that area.
筋肉との接触表面積を増加させるようになっている。人
体の腕の長さは固体差があるが２本発明の人工腱では術
中２編んだ部分２をほどくことにより適当な長さに調節
が可能である。Designed to increase surface area of contact with muscles. Although the length of human arms varies from person to person, the length of the artificial tendon of the present invention can be adjusted to an appropriate length by untying the two braided portions 2 during surgery.
又２本発明人工鍵の骨への附着部は、複数本のダクロン
糸１を生体側の鍵の残端、さらに骨を通して固定する。Further, in the attachment part of the artificial key of the present invention to the bone, a plurality of Dacron threads 1 are fixed through the remaining end of the key on the living body side and further through the bone.
これをこより、初期には骨により。From this, initially by bones.
時間が経てば鍵との結合により力が伝達される。Over time, the force is transferred through the combination with the key.
又、人工腱体部は初期にはそれ自体が滑走性を要求され
るため２表面に液体シリコンによる表面加工がなされて
おり、人工腱の滑走を助けるよう番こなされている。In addition, since the artificial tendon body itself is required to have sliding properties in the initial stage, two surfaces are treated with liquid silicone to help the artificial tendon slide.
本発明の人工腱は以上のように、従来の棒状人工腱のよ
うに鍵鞘作用の考想ではなく、複数本のダクロン糸を編

の内部および表面を自家組織で包埋するようになしたも
のである。従って本発明の人工腱は生体との癒着も強く
２体内で力学的作用可能な人工腱である。As described above, the artificial tendon of the present invention is not based on the concept of key sheath action like the conventional rod-shaped artificial tendon, but is made by weaving multiple Dacron threads to make the body of the artificial tendon flexible. It makes it easy for collagen fibers to enter into the voids of the body, and collagen fibers enter from the living body side at the transition areas with muscles and bones and bond, and these fibers also enter the key areas. The interior and surface of the artificial tendon are embedded with autologous tissue. Therefore, the artificial tendon of the present invention is an artificial tendon that has strong adhesion to a living body and is capable of mechanical action within two bodies.

との移行部には袋形網状体３を取付けてなる人工腱。A plurality of Dacron threads (trade name of saturated polyester polymer fiber manufactured by DuPont, USA) are knitted to make the body part 2 of the artificial tendon flexible and to connect it to the muscles of the artificial tendon. An artificial tendon in which a bag-shaped mesh body 3 is attached to the transition part.
