Description

本発明は、生体の骨関節を代替するために用いられる人工関節に関する。   The present invention relates to an artificial joint used for replacing a bone joint of a living body.

一般に、人工関節は、生体内の骨関節の変形や欠損を代替するために、整形外科等の治療に広く用いられている。   In general, artificial joints are widely used in treatments such as orthopedics in order to replace the deformation and loss of bone joints in a living body.

図６は従来の人工関節の一例を示す説明図である。   FIG. 6 is an explanatory view showing an example of a conventional artificial joint.

図６に示すように、従来の人工関節５０は、一方の骨Ｈ１に取り付けられる人工骨頭５１と、他方の骨Ｈ２に取り付けられる人工受座５２（ソケット）とから構成されている。   As shown in FIG. 6, the conventional artificial joint 50 includes an artificial bone head 51 attached to one bone H1 and an artificial seat 52 (socket) attached to the other bone H2.

人工骨頭５１は、頭部５１ａと、頭部５１ａに連結されたネック部５１ｂと、ネック部５１ｂに連結され、一方の骨Ｈ１に形成された穴５１ｃに埋入して固着するステム部５１ｄとを有する。   The artificial bone head 51 includes a head portion 51a, a neck portion 51b connected to the head portion 51a, a stem portion 51d connected to the neck portion 51b, and embedded and fixed in a hole 51c formed in one bone H1. Have

人工受座５２は、凹状に湾曲して形成された凹部５２ａを有し、他方の骨Ｈ２には、金属製のスクリュウ（ねじ）による捩じ込みや骨セメントによる接着によって固着される。   The artificial seat 52 has a concave portion 52a that is curved in a concave shape, and is fixed to the other bone H2 by screwing with a metal screw (screw) or adhesion with bone cement.

人工骨頭５１の頭部５１ａは人工受座５２の凹部５２ａ内に嵌合され、これによって、人工骨頭５１は人工受座５２に回動可能に連結される（例えば特許文献１参照）。
特開平１１−１２８２５５号公報 The head 51a of the artificial bone head 51 is fitted into the recess 52a of the artificial seat 52, and thereby the artificial bone head 51 is rotatably connected to the artificial seat 52 (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-128255

従来の人工関節では、人工骨頭のステム部を挿入し固着するために、骨の表面に深い穴を形成する必要があった。   In the conventional artificial joint, in order to insert and fix the stem portion of the artificial bone head, it is necessary to form a deep hole in the surface of the bone.

そのため、一度人工関節を取り付けてしまうと、磨耗による劣化、骨との間の緩み、人工関節自体の寿命等の問題が生じても、その箇所に新たな人工関節を再度取り付けることが非常に困難であるという課題があった。   Therefore, once a prosthesis is attached, it is very difficult to reattach a new prosthesis even if problems such as deterioration due to wear, loosening with the bone, or the life of the prosthesis itself occur. There was a problem of being.

本発明は、上記課題を解決するためになされたものであり、骨に深い穴を形成することなく、何度でも取り付けることができる人工関節を提供することを目的とする。   The present invention has been made to solve the above problems, and an object thereof is to provide an artificial joint that can be attached any number of times without forming a deep hole in a bone.

本発明の人工関節は、弾力性のある代替物を皮膚の外部から生体の骨関節の変形部分や欠損部分に注入して形成されることを特徴とするものである。   The artificial joint of the present invention is characterized in that it is formed by injecting an elastic substitute from outside the skin into a deformed part or a defective part of a bone joint of a living body.

前記代替物はシリコン樹脂であってもよい。   The alternative may be a silicone resin.

前記代替物と骨との間に潤滑油が注入されていてもよい。   Lubricating oil may be injected between the substitute and the bone.

本発明の人工関節によれば、生体の骨関節の欠けた骨片や小片の残骸を除去した後に、注射器等を用いて、代替物を皮膚の外部から骨関節の変形部分や欠損部分に注入して形成される。これによって、代替物の弾力性を利用して関節部を支えるので、接着剤を用いることなく、容易に製作することができる。
また、人工関節の治療が行われるまでの期間が長くなると、関節部が固まり筋肉や腱が縮んでしまうので、それを防止するために、人工関節を取り付けるまでの間、一時的に上記代替物を注入して形成してもよい。 According to the artificial joint of the present invention, after removing bone fragments or small pieces debris from a living bone joint, a substitute is injected from the outside of the skin into the deformed or defective portion of the bone joint using a syringe or the like. Formed. As a result, the joint portion is supported by utilizing the elasticity of the substitute, so that it can be easily manufactured without using an adhesive.
In addition, if the period until the treatment of the artificial joint is prolonged, the joint portion is hardened and the muscles and tendons are contracted. It may be formed by injecting.
