An endo-therapy accessory is used in combination with an endoscope which has a forceps elevator. This endo-therapy accessory has an insertion portion of the endo-therapy accessory to be inserted into the endoscope. The insertion portion of the endo-therapy accessory has a forceps elevator fixing section set in a range of passing the elevator, and fixed when the elevator is lifted, and a main index for use in determining whether a part of the elevator fixing section, which is more proximal than a far end of the fixing portion, is located on the elevator.
