PROBLEM TO BE SOLVED: To provide a scope-assisted surgery excised object discharge device which has both functions of cut and collection of a lesion with an assist by a scope, is simple, light-weight, and compact, and improves low invasiveness, safety, reliability, operability, and efficiency.SOLUTION: In a scope-assisted surgery excised object discharge device 10, a cutting discharge processing part 60 includes: a bag 61 having an opening which can store an excised object, and is expanded and contracted into a closed state; a shape memory band 80 encapsulated in the opening periphery and the body in a loop shape and expands the opening; and a cutting wire 90 having plural loops, separated from a bag body in contraction, narrowed and cutting a lesion. By one-hand operation in a two-piece division operation part 20 on a proximal end, an operation can be performed which allows the cutting discharge processing part to be pressed out from a tip opening of an insertion tube part 50 to be expanded to cut into small pieces and collect the lesion, and pulled into the insertion tube in a contracted state to discharge the lesion outside a living body.SELECTED DRAWING: Figure 1 |
