Abstract:
(EN) [Problem] To provide a medical instrument having a compact and lightweight operation section. [Solution] An outer sheath 22 having an inner sheath 21 inserted therein is pulled in into the housing 31 of an operation section 3, and a coiled member 22a having protrusions and recesses on the outside thereof is mounted to the proximal end section of the outer sheath 22. When a button 33 is pushed in against the pressing force of a coiled spring 35, the front end of a plate spring 33a engages with some of the protrusions and recesses of the coiled member 22a, and the outer sheath 22 is slid toward the proximal end. When the button 33 is released from the pushing operation, the front end of the plate spring 33a is returned to the original position by the pushing force of the coiled spring 35 without engaging with the coiled member 22a. Repeating the pushing and releasing of the button 33 can slide the outer sheath 22 toward the proximal end by a predetermined amount.
(FR) Le problème décrit par la présente invention est de fournir un instrument médical ayant une section d'actionnement compacte et légère. La solution selon l'invention porte sur une gaine externe 22 ayant une gaine interne 21 insérée à l'intérieur de celle-ci, qui est tirée dans le logement 31 d'une section de fonctionnement 3, et un élément spiralé 22a ayant des saillies et des évidements sur l'extérieur de celui-ci est monté sur la section d'extrémité proximale de la gaine externe 22. Lorsqu'un bouton 33 est poussé contre la force de pression d'un ressort hélicoïdal 35, l'extrémité avant d'un ressort de plaque 33a vient en prise avec certaines des saillies et des évidements de l'élément spiralé 22a, et la gaine externe 22 est glissée vers l'extrémité proximale. Lorsque le bouton 33 est libéré de l'opération de poussée, l'extrémité avant du ressort de plaque 33a est renvoyée à la position d'origine par la force de poussée du ressort hélicoïdal 35 sans venir en prise avec l'élément spiralé 22a. La répétition de la poussée et de la libération du bouton 33 peut faire coulisser la gaine externe 22 vers l'extrémité proximale par une quantité prédéterminée.
(JA) 【課題】操作部の小型・軽量化を図ることができる医療用器具を提供すること。 【解決手段】操作部3のハウジング31内にインナーシース21が挿通されたアウターシース22が引き込まれており、アウターシース22の近位端部には外側に凹凸を有するコイル部材22aが取り付けられている。ボタン33をコイルバネ35の付勢力に抗して押し込むと、板バネ33aの先端がコイル部材22aの凹凸の一部に係合し、アウターシース22が近位端側にスライドされる。ボタン33の押圧を解除すると、板バネ33aの先端はコイル部材22aに係合することなく、コイルバネ35の付勢力により元に戻る。ボタン33の押圧およびその解除を繰り返すことにより、アウターシース22を近位端側に所定量だけスライドさせることができる。
