Abstract
(EN)
An endoscopic treatment instrument comprising: a sheath (2) that has a longitudinal axis; a first manipulation wire (4a) and a second manipulation wire (4b) that are retractably inserted into the sheath (2); a treatment unit (5) that is constituted by a first wire rod (11a) and a second wire rod (11b) that have a lower bending stiffness than the bending stiffness of the second manipulation wire (4b); a first junction (6) through which the second wire rod (11b) passes and which joins the distal end of the first manipulation wire (4a) and the basal end of the first wire rod (11a); and a second junction (7) that joins the distal end of the second manipulation wire (4b) and the basal end of the second wire rod (11b).
(FR)
L'invention concerne un instrument de traitement endoscopique comprenant : une gaine (2) qui présente un axe longitudinal ; un premier fil de manipulation (4a) et un deuxième fil de manipulation (4b) qui sont insérés de manière rétractable dans la gaine (2) ; une unité de traitement (5) qui est constituée d'une première tige métallique (11a) et d'une deuxième tige métallique (11b) qui ont une rigidité à la flexion inférieure à la rigidité à la flexion du deuxième fil de manipulation (4b) ; une première jonction (6) à travers laquelle passe la deuxième tige métallique (11b) et qui relie l'extrémité distale du premier fil de manipulation (4a) et l'extrémité de base de la première tige métallique (11a) ; et une deuxième jonction (7) qui relie l'extrémité distale du deuxième fil de manipulation (4b) et l'extrémité de base de la deuxième tige métallique (11b).
(JA)
長手軸を有するシース(2)と、シース(2)に進退可能に挿通された第1操作ワイヤ(4a)および第2操作ワイヤ(4b)と、第2操作ワイヤ(4b)の曲げ剛性よりも小さい曲げ剛性を有する第1線材(11a)および第2線材(11b)により構成された処置部(5)と、第2線材(11b)が内部を通過し、かつ、第1操作ワイヤ(4a)の先端部と第1線材(11a)の基端部とを接合する第1接合部(6)と、第2操作ワイヤ(4b)の先端部と第2線材(11b)の基端部とを接合する第2接合部(7)とを備える内視鏡用処置具である。
