PROBLEM TO BE SOLVED: To provide an introduction assisting device with a side hole which reduces the occurrence of flattening or kinking of a portion where the side hole is provided, while securing the flexibility of a tubular body to be inserted within a tubular organ.SOLUTION: An introduction assisting device 11 comprises a tubular body 13 to be inserted to a tubular organ of a human body, the tubular body 13 having a side hole 27 provided in its peripheral wall, which makes it possible to introduce a medical device 21 into the tubular organ through the side hole 27 in the tubular body 13. The tubular body 13 comprises a flexible body portion 23 and a rigid portion 25 provided at the intermediate portion of the body portion 23 and being more rigid than the body portion 23. In order to make the rigid portion 25 flexible, a slit 29 is formed in the peripheral wall of the rigid portion 25.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】側孔付き導入補助器具において、管状器官内に挿入される管状体の柔軟性を確保しつつ側孔を設けた部分の潰れやキンクの発生を低減させる。【解決手段】導入補助器具11は、人体の管状器官内へ挿入される管状体13を備え、管状体13の周壁に側孔27が設けられており、管状体13の側孔27を通して管状器官内へ医療器具21を導入させることができる。管状体13が、撓曲可能な本体部分23と、本体部分23の中間部に設けられ且つ本体部分23よりも剛性の高い剛性部分25とを含み、剛性部分25に柔軟性を付与するように剛性部分25の周壁にスリット29が形成されている。【選択図】図1
