摘要：
Provided are a bending method and a bending apparatus for bending a medical suturing needle into different curved shapes by using one bending top. The bending apparatus comprises a reciprocally rotatable bending top, and a belt having such a flexibility as can be wound on the outer circumference of the bending top. The bending method curves a medical suturing needle by sandwiching and constricting a material for the medical suturing needle between the bending top and the belt and by rotating the bending top reciprocally in the winding direction and in the rewinding direction. In the bending method, the curved shape of the material is changed by changing the winding angle of the belt to be wound on the outer circumference of the bending top thereby to change the area for constricting the material. The bending apparatus (B) comprises a reciprocally rotatable bending top (11), and a belt (12) having such a flexibility as can be wound on the outer circumference of the bending top (11), and is constituted such that a winding angle (θ) for the belt (12) to be wound on the outer circumference of the bending top (11) is changed.
摘要（中）：
提供一种通过使用一个弯曲顶部将医疗缝合针弯曲成不同的弯曲形状的弯曲方法和弯曲装置。 弯曲装置包括可往复旋转的弯曲顶部和具有可弯曲弯曲顶部的外圆周上的柔性的带。 弯曲方法通过在弯曲顶部和带之间夹住和收缩用于医疗缝合针的材料并且通过沿弯曲方向和倒带方向往复地旋转弯曲顶部来弯曲医用缝合针。 在弯曲方法中，通过改变卷绕在弯曲顶部的外周上的带的卷绕角度来改变材料的弯曲形状，从而改变用于收缩材料的区域。 弯曲装置（B）包括可往复旋转的弯曲顶部（11）和具有可弯曲弯曲顶部（11）的外周上具有柔性的带（12），并且构成为使卷绕角度 改变了用于缠绕在弯曲顶部（11）的外圆周上的带（12）的（和）长度。
