    • PROBLEM TO BE SOLVED: To provide a slit pipe in which a torque transmission property at least in one-way rotation is improved and which is prevented from being axially elongated/contracted, a slit pipe capable of easily adjusting rigidity or a slit pipe in which a torque transmission property balanced on a circumferential cross section is improved, or a guide wire which employs the slit pipe and can be easily manufactured.SOLUTION: A slit pipe 1 comprises, in any other region than both end portions in a length direction, a slit 5 which is formed spirally with respect to the length direction, and a plurality of beams formed in the middle of the spiral slit so as to be spread over the slit. Thus, not only the slit pipe per se is made flexible to prevent slit pipe end portions from being loosened but also a torque transmission property at least in one-way rotation is improved and the slit pipe can be prevented from being axially elongated/contracted.
    • 要解决的问题:为了提供一种狭缝管,其中至少在单向旋转中的转矩传递特性得到改善并且防止其被轴向拉伸/收缩,可以容易地调节刚度的狭缝管或狭缝管,其中 提高了在周向截面上平衡的扭矩传递性能,或者采用狭缝管的导丝,并且可以容易地制造。解决方案:狭缝管1在长度方向上的两个端部的任何其他区域中, 狭缝5,其相对于长度方向螺旋地形成,并且多个梁形成在螺旋狭缝的中间以分布在狭缝上。 因此,不仅使狭缝管本身柔软,以防止狭缝管端部松动,而且至少在单向旋转中的转矩传递性能得到改善,并且可以防止狭缝管轴向伸长/收缩。

    • PROBLEM TO BE SOLVED: To provide a guide wire which is excellent in torque force, and at the same time, can prevent the plastic deformation of a core shaft from occurring.SOLUTION: The guide wire includes: the core shaft which includes a first leading end section and a first rear end section being located on the opposite side from the first leading end section; and a coil body which includes a second leading end section and a second rear end section being located on the opposite side from the second leading end section, and is wound around the outer periphery of the first leading end section. The core shaft is constituted by including a first cylindrical section to which the second rear end section is fixed; a second cylindrical section which is located closer to the first rear end section side than the first cylindrical section; and a third cylindrical section which is located closer to the first rear end section side than the second cylindrical section. The outer diameter of the second cylindrical section is larger than the outer diameter of the first cylindrical section, and also, is smaller than the maximum diameter of the coil body. The outer diameter of the third cylindrical section is larger than the outer diameter of the second cylindrical section, and also, is smaller than the maximum diameter of the coil body.
    • 要解决的问题:提供扭矩力优异的导丝,同时可以防止芯轴发生塑性变形。 导丝包括:芯轴,其包括第一前端部和位于与第一前端部相反的一侧的第一后端部; 以及线圈体,其包括位于与所述第二前端部相反的一侧的第二前端部和第二后端部,并且缠绕在所述第一前端部的外周。 芯轴由固定有第二后端部的第一圆筒部构成, 位于比第一圆筒部更靠近第一后端部侧的第二圆筒部; 以及比第二圆筒部更靠近第一后端部侧的第三圆筒部。 第二圆筒部的外径大于第一圆筒部的外径,也小于线圈体的最大直径。 第三圆筒部的外径大于第二圆筒部的外径,也小于线圈体的最大直径。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a guide wire for an endoscope easy to exhibit a fixing function to the endoscope regardless of the position relationship between the duodenal papilla and the endoscope.SOLUTION: The guide wire for the endoscope includes an element wire 11 having an elongated body section 114 and a distal portion 111 reduced in diameter from the body section; a resin coating section 12 coating the body section and distal portion and having the smooth outer surface; and a visible mark provided at the resin coating section. The body section has a flexible part 115 forming a part of the body section and lower in flexural rigidity than the other part 116 of the body section different from the part. The visible mark is provided in a position of coating the flexible part in the resin coating section.
    • 要解决的问题:无论十二指肠乳头和内窥镜之间的位置关系如何,为内窥镜提供易于对内窥镜的定影功能的导丝。 解决方案:用于内窥镜的导丝包括具有细长主体部分114和远离部分111的直径从主体部分减小的元件导线11; 涂覆主体部分和远端部分并且具有光滑的外表面的树脂涂覆部分12; 以及设置在树脂涂布部的可见标记。 主体部分具有形成主体部分的一部分的柔性部分115,并且弯曲刚度低于与该部分不同的主体部分的其他部分116。 可见标记设置在将柔性部件涂覆在树脂涂覆部分中的位置。 版权所有(C)2012,JPO&INPIT
