PROBLEM TO BE SOLVED: To provide a medical device capable of making a stable puncture of a desired puncture depth without blocking a living body lumen.SOLUTION: A medical device 10A comprises an insertion tube 12 which has a curvable section 20 and is insertable into a living body. The curvable section 20 includes a plurality of tubular bodies 24 connected rotatably with each other. The medical device 10A further comprises: a curvature drive member 14 which is arranged inside the insertion tube 12 and drives the curvable section 20 and a needle member 16 which is arranged inside the insertion tube 12 and can protrude through a curvature outer peripheral side gap between adjacent tubular bodies 24 when the curvable section 20 is bent.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】生体管腔を閉塞することなく所望の穿刺深さで安定して穿刺をすることができる医療用デバイスを提供する。【解決手段】医療用デバイス10Aは、湾曲可能な湾曲部20を有し生体内に挿入可能な挿入管12を備える。湾曲部20は、互いに回動可能に連結された複数の管状体24を有する。医療用デバイス10Aはさらに、挿入管12の内側に配置され湾曲部20を駆動する湾曲駆動部材14と、挿入管12の内側に配置され、湾曲部20が湾曲しているときに、隣接する管状体24間の湾曲外周側の隙間から突出可能な針部材16とを備える。【選択図】図1
