PROBLEM TO BE SOLVED: To provide a peeling device and a peeling system excellent in workability when collecting a blood vessel together with its peripheral tissue.SOLUTION: A peeling device 14 includes a grip part 44 having an insertion lumen into which an imaging device 17 can be inserted and a peeling member 46 provided at the tip of the grip part 44. The peeling member 46 includes a peeling part 50 provided with a treatment part 60 for executing a predetermined treatment to a branched blood vessel 73 branched from a blood vessel 72, and a protrusion part 90 protruding in a thickness direction of the peeling part 50 from the peeling part 50. The protrusion part 90 includes a guide part 92 for guiding the branched blood vessel 73 toward the treatment part 60.SELECTED DRAWING: Figure 5【課題】血管をその周辺組織とともに採取する際の作業性に優れる剥離デバイス及び剥離システムを提供する。【解決手段】剥離デバイス１４は、撮像デバイス１７が挿入可能な挿入ルーメンを有する把持部４４と、把持部４４の先端部に設けられた剥離部材４６とを備える。剥離部材４６は、血管７２から分岐した分岐血管７３に所定の処理を行う処理部６０が設けられた剥離部５０と、剥離部５０から剥離部５０の厚さ方向に突出した突出部９０とを有する。突出部９０は、処理部６０に向けて分岐血管７３を案内するガイド部９２を有する。【選択図】図５
