Title (EN) ENDOSCOPE BENDING SECTION AND ENDOSCOPE
(FR) SECTION DE COURBURE D'ENDOSCOPE ET ENDOSCOPE
(JA) 内視鏡湾曲部および内視鏡
Abstract:
(EN) An endoscope bending section 7 is provided with: two lumens 31, 32 formed from a multi-lumen tube and in which a pair of bending operation wires 27, 28 for bending along a first direction U and a second direction D opposite to the first direction U are individually inserted; and bending direction restricting members 41, 42 provided on a second axis LR orthogonal to a first axis UD passing through a central axis X along the first direction U and the second direction D, the bending direction restricting members 41, 42 restricting bending in the direction of the second axis LR.
(FR) Une section de courbure d'endoscope 7 est pourvue : de deux lumières 31, 32 formées à partir d'un tube à lumières multiples et dans lesquelles une paire de fils d'opération de flexion 27, 28 destinées à se plier le long d'une première direction U et d’une seconde direction D opposée à la première direction U est insérée individuellement ; et d'éléments de limitation de direction de courbure 41, 42 disposés sur un second axe LR orthogonal à un premier axe UD passant par un axe central X le long de la première direction U et de la seconde direction D, les éléments de restriction de direction de courbure 41, 42 limitant la courbure dans la direction du second axe LR.
(JA) 内視鏡湾曲部7は、マルチルーメンチューブから形成され、第1の方向Uおよび、第1の方向Uとは反対の第2の方向Dに沿って湾曲操作するための一対の湾曲操作ワイヤ27,28が個別に挿通される2つのルーメン31,32と、第1の方向Uと第2の方向Dに沿った中心軸Xを通る第1の軸UDに直交した第2の軸LR上に設けられ、第2の軸LR方向への曲がりを規制する湾曲方向規制部材41,42と、を具備する。
