SYSTEM, DETERMINATION METHOD, MEDICAL EQUIPMENT MANUFACTURING METHOD, AND DETECTION UNIT

To provide a system capable of easily determining a movement state of long-sized equipment, a determination method, a medical equipment manufacturing method, and a detection unit.SOLUTION: An endoscope system 200 includes a magnetism detection part 43, an insertion part 10 of an endoscope 1 used by being relatively moved with respect to the magnetism detection part 43, and a processor 4P. The insertion part 10 includes a tubular member 17 extending in a longitudinal direction X, in which a magnetic pattern is formed along the longitudinal direction X. The magnetism detection part 43 detects flux density BX of the longitudinal direction X and flux density BY of a radial direction Y in a plurality of positions along the longitudinal direction X of the tubular member 17. The processor 4P determines a movement state to the longitudinal direction X of the insertion part 10 on the basis of the flux density BX and the flux density BY.SELECTED DRAWING: Figure 9 【課題】長尺状の器具の移動状態を容易に判定可能なシステム、判定方法、医療用機器の製造方法、及び検出ユニットを提供する。【解決手段】内視鏡システム２００は、磁気検出部４３と、磁気検出部４３に対し相対移動させて用いられる内視鏡１の挿入部１０と、プロセッサ４Ｐと、を備え、挿入部１０は、長手方向Ｘに延び且つ磁気パターンが長手方向Ｘに沿って形成された管状部材１７を有し、磁気検出部４３は、管状部材１７の長手方向Ｘに沿った複数の位置において、長手方向Ｘの磁束密度ＢＸと径方向Ｙの磁束密度ＢＹを検出し、プロセッサ４Ｐは、磁束密度ＢＸ及び磁束密度ＢＹに基づいて、挿入部１０の長手方向Ｘへの移動状態を判定する。【選択図】図９
