PROBLEM TO BE SOLVED: To provide a wire for detecting a lymphatic vessel position suitable for a lymphatic vessel and vein anastomosis operation that requires visual recognition of the lymphatic vessel position of a living body with an ultrasonic echo.SOLUTION: A first wire for detecting a lymphatic vessel position of the invention comprises as a main material a core wire material 12 in the round rod shape having a marker 15 for ultrasonic visual recognition arranged at a proper position in the axial direction and a tapered tip part 14 processed so that its diameter is gradually reduced, and is configured so that the outer diameter of the core wire material 12 has the thickness capable of being inserted into the lymphatic vessel of a living body. A second wire for detecting a lymphatic vessel position of the invention comprises: a core wire material in the round rod shape or flat plate shape having a marker for ultrasonic visual recognition arranged at a proper position in the axial direction and a pipe material having a tapered tip part processed so that its diameter is gradually reduced, and is configured so that the tip protrudes from the tapered tip part of the pipe material, and the outer diameter of the pipe material into which the core wire material is inserted has the thickness capable of being inserted into the lymphatic vessel of a living body.COPYRIGHT: (C)2016,JPO&INPIT【課題】超音波エコーによる生体のリンパ管位置の視認が必須なリンパ管静脈吻合手術に好適なリンパ管位置検出用ワイヤの提供。【解決手段】第1の発明は、軸方向での適宜位置に配設された超音波視認用マーカー15と、その径が次第に細くなるように加工されたテーパー先端部14とを備えて丸棒状を呈する芯線材12を主材とし、該芯線材12の外径を生体のリンパ管内への挿入が可能な太さとして構成されている。また、第2の発明は、軸方向での適宜位置に配設された超音波視認用マーカーを備えた丸棒状または平板状を呈する芯線材と、その径が次第に細くなるように加工されたテーパー先端部を有するパイプ材とを具備し、パイプ材の前記テーパー先端部からその先端部が突出するようにして前記芯線材が挿入された前記パイプ材の外径が生体のリンパ管内への挿入が可能な太さを有して構成されている。【選択図】図1
