Abstract:
PURPOSE: To achieve miniaturization of one piping tool while improving airtightness of the piping device by connecting two treating tool insertion ports and two channels with the separate piping tools respectively.
CONSTITUTION: A cap 34 having a forceps port 28 formed therein is fixed at an upper part of an insertion path 36 formed at a protruded part 26. Then, a cylindrical piping tool 38 is connected to a lower part of the cap 34 and further to a forceps channel through a cylinder body 40 and a connector 42. Further, the cap 68 having a forceps port 30 formed therein likewise is fixed at an upper part of another insertion path 70 formed at the protruded part 26. A cylindrical piping tool 72 is connected at a lower part of the cap 68 and further to the forceps channel through a cylinder body 74 and a connector 76. This achieves miniaturization of the piping tool 72 while improving airtightness of the piping tools 38 and 72 with O rings 56, 58, 88, and 90.
