Title: (EN) ENDOSCOPIC INSTRUMENT
(ZH) 内窥镜处置器具
Abstract: front page image
(EN) In order to stably alter the gripping direction of forceps while keeping the position of the forceps constant, this endoscopic instrument (1) is provided with: a sheath (2) that has a conduit throughwhich fluid can be supplied, and that can be inserted inside a channel of an endoscope; a forceps part (3) that is provided with a pair of forceps pieces (3a), which protrudes from a tip cover (30) provided at the tip of the sheath (2), and a bracket (3c) that supports the forceps pieces (3a) so that the forceps pieces (3a) can open and close; a manipulation member (4d), which is connected to theproximal end of the forceps pieces (3a), for opening and closing the forceps pieces (3a) by moving backwards and forwards in the longitudinal direction; and a flow path-forming member (7) that is fixed at the proximal end of the bracket (3c) and is positioned so as to be able to rotate around the central axis of the sheath (2). The flow path-forming member (7) is provided with recessed sections (7b) that are positioned in the direction orthogonal to the opening/closing direction of the forceps pieces (3a) with respect to the bracket (3c), and are inwardly depressed in the radial direction suchthat a fluid supply hole (8) is formed by a gap between the inner peripheral surface of the tip cover (30) and the recessed sections (7b).
(ZH) 以一边将钳子的位置维持为恒定一边稳定地变更钳子的把持的方向为目的,本发明的内窥镜处置器具(1)包括:护套(2),其具有能够送液的管路,并能够向内窥镜的通道内插入;钳子部(3),其具备配置为自设于护套(2)的顶端的顶端罩(30)突出的突出状态的一对钳子片(3a)和将钳子片(3a)支承为能够开闭的支架(3c);操作构件(4d),其连接于钳子片(3a)的基端,该操作构件通过沿长度方向前进后退而使钳子片(3a)开闭;以及流路形成构件(7),其固定于支架(3c)的基端,该流路形成构件配置为能够绕护套(2)的中心轴线旋转,流路形成构件(7)具备凹部(7b),该凹部(7b)相对于支架(3c)沿与钳子片(3a)的开闭方向正交的方向配置且向径向内侧凹陷,利用该凹部与顶端罩(30)的内周面之间的间隙形成送液孔(8)。
