Abstract

【課題】長さ方向に異なる曲率半径を持って湾曲した医療用縫合針をより合理的に曲げ加工する方法を提供する。 【解決手段】 長さ方向に異なる曲率半径（ｒ、Ｒ）で湾曲させる曲げ加工方法であって、往復回動する曲げコマ１１の外周面を長さ方向に異なる曲率半径で湾曲する縫合針Ａの湾曲形状に対応させた成形面１１ａ～１１ｃを形成しておき、曲げコマ１１の外周面とプレスロール１４とを可撓性を有するベルト１２を挟んで相対的に押圧させ、曲げコマの外周面とプレスロール１４とが押圧する点Ｐに於ける曲げコマ１１の外周面とベルト１２との間に棒状の素材１を挟み込むと共に曲げコマを巻込方向（矢印ａ方向）及び巻戻方向（矢印ｂ方向）に往復回動させることで、素材１を長さ方向に異なる曲率半径で湾曲させる。
