PROBLEM TO BE SOLVED: To provide an excellently convenient needle set for epidural and spinal anesthesia, capable of highly accurately projecting the edge point of a spinal needle from a through-hole even when the through-hole of an epidural external needle is arranged at the lower side (the rear side of an edge surface) from the center of a needle tube axis, and allowing the spinal needle not to be normally pressurized during the insertion of the needle.SOLUTION: The needle set includes: the needle (the epidural external needle) for epidural anesthesia, where the distal end of an external needle 1 is curved and the through-hole 114 is arranged in the rear surface of the curvature part 113 and the needle 3 (the spinal needle) for spinal anesthesia, which is put through the external needle inner cavity of the epidural external needle 1 and is used by projecting the distal end part from the through-hole 114. The spinal needle 3 includes a bent part 312, formed by a plurality of bending points such as a V shape in the middle of the needle tube 31. The needle tube axis at the distal end side is slightly inclined compared with the needle tube axis at the proximal side by holding the bending part 312.COPYRIGHT: (C)2009,JPO&INPIT【課題】硬膜外針の貫通孔が、針管軸中心より下側(刃面の裏側より)にあっても、高い精度でスパイナル針の刃先を貫通孔から突出させることができ、また、スパイナル針挿入中、常に針を押さえていなくても良い、使い勝手に優れた硬脊麻針セットを提供すること。【解決手段】外針1の先端を湾曲すると共に、該湾曲部113背面に貫通孔114を設けた硬膜外麻酔のための針(硬膜外針)と、前記硬膜外針1の外針内腔に挿通され、前記貫通孔114より先端部を突出させて用いる脊髄麻酔のための針3(スパイナル針)とからなるセットにおいて、前記スパイナル針3が、針管31の中途でV字形状などの複数の曲点よりなる曲がり部312を備え、該曲がり部312を挟み、先端側の針管軸が基側の針管軸に比して僅かに傾斜するように形成した。【選択図】 図1
