    • A medical instrument including a distortion detection probe disposed in an insertion portion to be inserted into the interior of an examinee provided with a plurality of FBG sensor sections that detect distortion of the insertion portion, a coordinate calculation section that calculates first three-dimensional coordinates of the respective FBG sensor sections according to a first three-dimensional coordinate system whose origin is a predetermined position based on the detection results of the FBG sensor sections, a coordinate system setting section that sets a second three-dimensional coordinate system based on the first three-dimensional coordinates of the respective FBG sensor sections, a coordinate transformation section that transforms the first three-dimensional coordinates of the respective FBG sensor sections into second three-dimensional coordinates according to the second three-dimensional coordinate system set by the coordinate system setting section and a shape display section that displays the shape of the insertion portion based on the second three-dimensional coordinates transformed by the coordinate transformation section.
    • 一种医疗器械,其特征在于,包括设置在被插入到被检体的内部的插入部的畸变检测探针,所述受检者设置有检测所述插入部的变形的多个FBG传感器部,计算第一三维坐标 根据基于FBG传感器部的检测结果的原点为预定位置的第一三维坐标系的各个FBG传感器部,基于前三个坐标系设定第二三维坐标系的坐标系设定部 相应FBG传感器部分的三维坐标,根据由坐标系设置部分设置的第二三维坐标系将各个FBG传感器部分的第一三维坐标变换为第二三维坐标的坐标变换部分 和形状显示部 基于由坐标变换部变换的第二三维坐标显示插入部的形状。
