I form vascular peeling device 1 and the base end side portion 30 made of resin is formed in a bar shape longer and thicker than the distal end portion 20 and the distal end portion 20 made of metal formed into a thin rod shape. To form the holding portion 25 of the hook-shaped holding by hooking the tip of the vein distal end portion 20. I form a curved portion 24 to the base end side than the holding portion 25 of the distal end portion 20. I want to form a tapered surface portion 26 on the proximal side than the curved portion 24 of the distal end portion 20. I want to form a tapered surface portion 31 so as to be continuous with the tapered surface 26 of the distal end portion 20 at the proximal end side 30. Is peeled from the supporting structure by pulling in a direction away from the supporting tissue vein by inserting sequentially the tapered surface portion 26, 31 and the bending portion 24 between the supporting tissues and veins hooked on the holding portion 25.細い棒状に形成された金属製の先端側部20とこの先端側部20よりも太くかつ長い棒状に形成された樹脂製の基端側部30とで血管剥離具1を構成する。先端側部20の先端に静脈を引っ掛けて保持するフック状の保持部25を形成する。先端側部20の保持部25よりも基端側に湾曲部24を形成する。先端側部20の湾曲部24よりも基端側にテーパ面部26を形成する。基端側部30に先端側部20のテーパ面部26に連続するようにテーパ面部31を形成する。保持部25に引っ掛けた静脈と支持組織との間に湾曲部24及びテーパ面部26、31を順に挿入して静脈を支持組織から離れる方向に引っ張って該支持組織から剥がす。
