Abstract
(EN)
This puncture needle (1) for medical use is provided with a distal end section (2) including the needle point (8) and is also provided with a body section (3) continuous with the distal end section (2) and having a substantially circular cross-sectional outer shape. In a single imaginary plane (X) including the center axis (O) of the body section (3), the distal end section (2) comprises blade surfaces (5, 6) consisting of curved surfaces, the angle (θ) of the blade surfaces (5, 6) measured relative to the imaginary plane (X) in a cross-section perpendicular to the direction of the center axis gradually decreasing in the direction of the center axis toward the needle point (8).
(FR)
La présente aiguille à ponction (1) à usage médical comporte une partie terminale distale (2) intégrant la pointe de l'aiguille (8), ainsi qu'une partie corps (3) dans la continuité de la partie terminale distale (2) présentant une forme extérieure essentiellement circulaire en coupe transversale. Dans un unique plan imaginaire (X) comprenant l'axe central (O) de la partie corps (3), la partie terminale distale (2) comprend des surfaces tranchantes (5, 6) constituées de surfaces incurvées, l'angle (θ) des surfaces tranchantes (5, 6) , comme mesuré par rapport au plan imaginaire (X) dans une coupe transversale perpendiculaire à la direction de l'axe central, diminuant progressivement dans la direction de l'axe central en allant vers la pointe de l'aiguille (8).
(JA)
 本発明に係る医療用の穿刺針(1)は、針先(8)を含む先端部(2)と、当該先端部(2)と連続し、略円形状の断面外形を有する本体部(3)と、を備え、前記本体部(3)の中心軸線(O)を含む1つの仮想平面(X)を設定した場合に、前記先端部(2)は、前記中心軸線方向において前記針先(8)側に向かうにつれて、前記中心軸線方向に直交する断面における前記仮想平面(X)に対する角度(θ)が漸減する、曲面で構成された刃面(5、6)を備える。
