This invention, endoscope cannula insertion and papillar incision technique and sphincter incision technique, is something regarding method and the device which execute the disposal which resembles to these. According to this case technology, endoscope cannula insertion and papillar incision technique of the entire bile duct, the disposal which resembles to these advances the device to inside the endoscope/the duodenum endoscope, the distal (2036) point of the device, is achieved by it tries to coming out outside of the endoscope at position of the fur Telecom papilla which it adjoins to the sphincter. Here, mechanism of the endoscope is operated, orientation does the distal (2036) point of the device to position of desire, does the appropriate cannula insertion of the bile duct. For example, sphincter incision tool, with consequence of mismatch of the anatomy region, and endoscope operation, it is difficult the accuracy and being consistent, to position sphincter incision tool for appropriate cannula insertion. With the steering unrestricted sphincter incision tool of this invention, the doctor the endoscope controls the position of the distal (2036) point of the device can adjust the mismatch of the device and the anatomy region unrelated. According to this invention, it can turn the steering wheel which installs the wire for cutting freely vis-a-vis the catheter. Being adhered by the cutting wire, it enters, but the steering wheel which is revolution possible, turning the wire, has provided the mechanism which transmits the power which turns the device point vis-a-vis the shaft of the catheter. If the steering wheel the proximal edge shaft turns unrelated in the proximal edge, there are no times when the whole shaft is made to twist, they are possible to grant power to the distal (2036) point directly. In addition, the revolution lock in order to maintain the orientation of the point, and/or, the rotary marking which shows the rotary quantity may have.本発明は、内視鏡カニュ
