PROBLEM TO BE SOLVED: To provide a choledochus illuminating drainage device for reducing risk of erroneously damaging a common hepatic duct during cholecystectomy.SOLUTION: This choledochus illuminating drainage device includes at least one optical fiber including at least one light emission structure on or inside a tube wall of a draining conduit tube. When the conduit tube enters a conduit of a living body, the optical fiber leads light from a light source such that the light is emitted from the light emission structure and is transmitted through the tube wall of the conduit tube and the conduit of the living body, so that a position of the conduit is indicated, and an operation peripheral region can be illuminated.COPYRIGHT: (C)2013,JPO&INPIT【課題】総胆管照明排液装置を提供する。【解決手段】この総胆管照明排液装置において、その排液用導管の管壁上又は管壁内に、少なくとも1つの出光構造を含む光ファイバーが少なくとも1本設けられている。前記導管は、生体の管路に入ると、その光ファイバーが、光源からの光を出光構造から射出させて導管の管壁と生体の管路に透過させるように導くことで、管路の位置を示し、手術周辺領域を照明することができる。【選択図】図5
