PROBLEM TO BE SOLVED: To provide a puncturing needle for epidural anesthesia, the distal end of which has no risk of bending, and which has excellent straightness as well.SOLUTION: In the puncturing needle for the epidural anesthesia whose distal end part is bent upwards and distal end face is turned to an upward inclined surface, the upper part of the distal end face is turned to a first inclined surface, while the lower part is turned to a second inclined surface, and the inclination of the second inclined surface is larger than the inclination of the first inclined surface. Since the second inclined surface of the large inclination is provided, the angle of the needle distal end can be increased, and the straightness is made excellent as well by the first inclined surface of the small inclination.COPYRIGHT: (C)2009,JPO&INPIT【課題】針先端が曲がるおそれがなく、直進性にも優れた硬膜外麻酔用穿刺針とする。【解決手段】先端部が上向きに屈曲し、先端面が上向きの傾斜面となっている硬膜外麻酔用穿刺針において、前記先端面の上部が第1傾斜面、下部が第2傾斜面となっており、該第2傾斜面の傾きが、前記第1傾斜面の傾きよりも大きい。傾きの大きな第2傾斜面を有するので、針先端の角度を大きくすることができ、傾きの小さな第1傾斜面により直進性にも優れる。【選択図】 図1
