Description

本考案はバイオニックサイエンスに関し、特に、人工骨に関するものである。
技術の発展に伴い、人間の寿命は長くなっている。しかし、年齢の増加に伴い、または、病気により、身体機能は低下する。そのため、天然臓器の代用となるバイオニック臓器が必要になっている。
上記の課題を解決するために、本考案は、元の骨の代わりに人工骨を使用し、支持柱と三次元多孔性足場構造を同時に設置した人工骨を提供する。これは、人工骨と元の骨の間の接続およびその後の骨細胞の成長に有利である。
上記の課題を解決するために、本考案は、バイオニック骨、支持柱および三次元多孔性足場構造を含み、前記支持柱と前記三次元多孔性足場構造が共に前記バイオニック骨に接続され、前記三次元多孔性足場構造が前記支持柱をカバーするように設けられる人工骨を提供する。
本考案のさらなる変更点は、以下のようである。
前記支持柱の自由端の形状が、実際の状況または患者の状況に応じて変動する。
前記支持柱は、二つの円柱および前記二つの円柱の間の角柱である。
前記角柱の断面が四角形である。
前記角柱の断面面積が前記円柱の断面面積より小さい。
前記支持柱が接続された元の骨の接続端内に挿入され、前記三次元多孔性足場構造が前記接続された元の骨の接続端をカバーするように設けられる。
前記三次元多孔性足場構造の孔隙の形状および大きさが、実際の状況または患者の状況に応じて変動する。
前記バイオニック骨、前記支持柱および前記三次元多孔性足場構造は一体構造である、もしくは、前記支持柱、前記三次元多孔性足場構造がそれぞれ前記バイオニック骨にスクリュースレッド接続（ネジ接続）される、もしくは、前記支持柱、前記三次元多孔性足場構造がそれぞれ前記バイオニック骨に焼結接続される。
従来の技術と比較して、本考案の有利な効果は、以下のようである。元の骨の代わりに人工骨を使用し、支持柱と三次元多孔性足場構造を同時に設置し、支持柱が接続された元の骨の接続端に挿入されることにより、元の骨を支持及び固定する。接続された元の骨の接続端の外周位置に三次元多孔性足場構造を設けることにより、骨細胞の付着と成長に便利な場所を提供し、人工骨と元の骨の接続部をより安定させる。

図面および実施形態を用い、本考案について詳しく説明する。
図1〜図3に示すように、バイオニック骨、支持柱および三次元多孔性足場構造を含み、支持柱と三次元多孔性足場構造が共にバイオニック骨に接続され、三次元多孔性足場構造が支持柱をカバーするように設けられる人工骨である。元の骨の代わりに人工骨を使用し、支持柱と三次元多孔性足場構造を同時に設置することにより、人工骨と元の骨の間の接続およびその後の骨細胞の成長に有利な効果を果たす。
本考案の支持柱は二つの円柱および前記二つの円柱の間の角柱であり、前記角柱の断面が四角形である。そのため、バイオニック骨の表面を滑らかにするためにサンディング、研削、研磨する際の固定部となり、また、支持柱と元の骨の間の回転シフトを防止することも可能になる。具体的には、角柱の断面面積が円柱の断面面積より小さい。該支持柱が接続された元の骨の接続端内に挿入され、三次元多孔性足場構造が該接続された元の骨の接続端をカバーするように設けられる。
本考案の三次元多孔性足場構造の孔隙の形状および大きさは、実際の状況または患者の状況に応じて変動する。
本考案のバイオニック骨は、代用する元の骨の三次元データに従って製造した。支持柱は、元の骨の傾きに従って製造した。人工骨の製造方法は、いくつかある。一つ，バイオニック骨、支持柱および三次元多孔性足場構造は一体構造である。コバルトクロム合金またはチタン合金を用い、3D金属プリンタにより直接プリントする。二つ、バイオニック骨、支持柱および三次元多孔性足場構造は一体構造である。チタン合金を用いて3D金属プリンタにより直接プリントした後、表面にコバルトクロム合金をコーティングする。三つ、支持柱、三次元多孔性足場構造がそれぞれバイオニック骨にスクリュースレッド接続される。すなわち、まず、コバルトクロム合金を用いて3D金属プリンタによりバイオニック骨を直接プリントし、また、チタン合金を用いて3D金属プリンタにより支持柱と三次元多孔性足場構造を直接プリントした後、支持柱と三次元多孔性足場構造をそれぞれバイオニック骨にスクリュースレッド接続させる。四つ、支持柱、三次元多孔性足場構造がそれぞれバイオニック骨に焼結接続される。すなわち、まず、コバルトクロム合金を用いて3D金属プリンタによりバイオニック骨を直接プリントし、また、チタン合金を用いて3D金属プリンタにより支持柱と三次元多孔性足場構造を直接プリントした後、支持柱と三次元多孔性足場構造をそれぞれバイオニック骨に焼結させる。
上記の内容は、本考案の好ましい実施形態であり、本考案の実施形態がこれに限定されることではない。本考案が属する技術分野の当業者が、本考案の思想から逸脱しない範囲内で行ういくつかの変更は、本考案の保護範囲に属すると見なされるべきです。
