    • PROBLEM TO BE SOLVED: To provide a medical tool which enables a function part to be sufficiently displaced even at a small bending angle by employing a structure capable of securing a large dimension in a longitudinal direction of a shape-memory part even without special enlargement of a length dimension of the whole tool.SOLUTION: A medical tool includes: a rod-shaped grip part 1 disposed at a base end; a function part 3 for use in a medical act, which is disposed at a tip; and a shape-memory part 2 made of a rod-shaped shape-memory alloy and disposed between the grip part 1 and the function part 3. The grip part 1 is provided with a holding part 1A having a space into which one end of the shape-memory part 2 is inserted from a longitudinal direction. A gap is provided between an outer surface of the shape-memory part 2 and an inner surface of the holding part 1A. When the shape-memory part 2 is bent, the shape-memory part 2 can be deformed within a range of the gap. The banding makes the outer surface of the shape-memory part 2 abut on an inner edge of an opening of the holding part 1A. Thus, the deformation of the shape-memory part 2 beyond a predetermined range can be regulated.
    • 要解决的问题:提供一种医疗用具,其能够通过采用能够在形状记忆部的纵向方向上确保大尺寸的结构,即使在没有特别扩大的情况下也能够以小的弯曲角度使功能部分充分位移 整个工具的长度尺寸。解决方案:医疗工具包括:设置在基端的杆状把手部分1; 用于医疗行为的功能部件3,其设置在尖端处; 以及由杆状形状记忆合金制成并配置在把手部1与功能部3之间的形状记忆部2。把持部1设有保持部1A,该保持部1A具有空间, 形状记忆部2从长度方向插入。 在形状记忆部2的外表面和保持部1A的内表面之间设有间隙。 当形状记忆部分2弯曲时,形状记忆部分2可以在间隙的范围内变形。 带状使得形状记忆部分2的外表面抵靠在保持部分1A的开口的内边缘上。 因此,能够调整形状记忆部2的超过规定范围的变形。
