  • Endoscope treatment-device and measuring method
    Publication number: 20040064015
    Abstract: An endo-therapy accessory device used in combination with an endoscope having an endo-therapy accessory channel includes a catheter and an endo-therapy accessory inserted into the catheter. The catheter is inserted into the endo-therapy accessory channel of the endoscope, and has a tip opening, and a first main-index recognized at a hand side in a predetermined position of a rear side from the tip opening. The endo-therapy accessory is inserted into the catheter so that its tip is recessed/projected from the tip opening, and has a second main-index in a position where a distance from the tip coincides with a distance from the tip opening of the catheter to the first main-index, and an insertion portion of the endo-therapy accessory to recognize a projection length when projected from the tip opening of the catheter based on a relative position of the second main-index with the first main-index of the catheter.
