摘要： An endoscope shape detection system has a CPU included in a control unit. The CPU performs frequency sampling of digital data to calculate coordinates indicating the spatial positions of source coils incorporated in an insertion unit of an endoscope received in a patient and of marker coils placed on a patient. An inserted state of the insertion unit of the endoscope is estimated based on the calculated coordinate data indicating the positions of the source coils. Display data based on the shape of the endoscope is produced from the calculated coordinate data indicating the positions of the source coils, and output to a video RAM. Display data of the marker coils is produced from the calculated coordinate data indicating the positions of the marker coils, and output to the video RAM. Consequently, the positions of the markers are depicted together with the shape of the endoscope. The positional relationship between the insertion unit of the endoscope and a patient's body can therefore be ascertained.

摘要翻译： 内窥镜形状检测系统具有包括在控制单元中的CPU。 CPU对数字数据进行频率采样，以计算表示收纳在患者的内窥镜的插入单元和放置在患者上的标记线圈的入射线圈的空间位置的坐标。 基于计算出的表示源极线圈的位置的坐标数据来估计内窥镜的插入单元的插入状态。 根据计算出的表示源极线圈的位置的坐标数据，生成基于内窥镜的形状的显示数据，并输出到视频RAM。 标记线圈的显示数据由计算出的表示标记线圈的位置的坐标数据产生，并输出到视频RAM。 因此，标记的位置与内窥镜的形状一起被描绘。 因此可以确定内窥镜的插入单元与患者身体之间的位置关系。

摘要： An endoscope includes an insertion section inserted into the body cavity and a probe provided inside the insertion section for detecting the form of the endoscope. The probe includes a plurality of coil portions arranged in the longitudinal direction of the insertion section of the endoscope and a wire electrically connecting the coil portions. The coil portions and the wire are covered with a flexible member. And the outer diameter of the covered wire is smaller than the outer diameter of the covered coil portions.
