Summary:PROBLEM TO BE SOLVED: To provide a blood vessel opening device which prevents a cut-off blood vessel piece from falling into a blood vessel.SOLUTION: A blood vessel opening device 100 comprises a blood vessel piece taking out bar 10 and a tubular blade 20. The blood vessel piece taking out bar 10 is a member which has an attachment part 11 attached to a portion of the blood vessel, at the distal end of a bar-like body 12. The tubular blade 20 is a member for cutting off a blood vessel around the attachment part 11 to bore a hole in a portion of the blood vessel. This makes it possible to prevent a blood vessel piece cut off by the tubular blade 20 from falling into the blood vessel.SELECTED DRAWING: Figure 1 【課題】切除された血管片が血管内に落ち込むことを防止する血管開口器を提供する。【解決手段】血管開口器１００は，血管片取出棒１０と筒状刃２０とを備える。血管片取出棒１０は，棒状の本体部１２の先端部位に，血管の一部に取り付けられる取付部１１を有する部材である。筒状刃２０は，取付部１１の周囲において血管を切除し，血管の一部をくり抜く部材である。これにより，筒状刃２０によって切除された血管片が血管内に落ち込むことを防止することが可能となる。【選択図】図１
