PROBLEM TO BE SOLVED: To provide a blood vessel ablation device excellent in workability of blood vessel harvesting.SOLUTION: A blood vessel ablation device 100 includes a long guide part 200 arranged along an outer wall of a blood vessel and a movable part 300 connected to the guide part 200 that includes an annular part 340 arranged around the blood vessel. By moving the annular part 340 while guiding it by the guide part 200, the blood vessel is ablated in a state of being covered with tissues in the surrounding. The guide part 200 includes a tubular body part 210 and an ablation part 220 having optical transparency provided at the tip of the body part 210. An imaging device having an imaging part can be inserted into the body part 210.SELECTED DRAWING: Figure 1 |
