摘要:
Provided is an endoscopic duct cleaning tool which uses elastic porous members to prevent the inside of a duct of an endoscope from being damaged, and which can firmly fix the elastic porous members to a core wire and secure a sufficient thickness in each of the elastic porous members.This endoscopic duct cleaning tool 1 is inserted into a duct 53 of an endoscope 50 to clean the duct 53. The endoscopic duct device 1 includes a core wire 10 consisting of a stranded wire, plural cylindrical elastic porous members 20 disposed at certain intervals and at certain places in an axial direction of the core wire 10 so as to cover an outer circumference of the core wire 10 directly, and resin tubes 30 covering outer circumferences of portions of the core wire 10 which are not covered with the elastic porous members 20. An outer diameter of each of the resin tubes 30 is formed to be larger than an inner diameter of each of the elastic porous members 20. A frontmost end tube 31 and a basemost end tube 32 disposed in a frontmost end portion and a basemost end portion of the core wire 10 respectively are fixedly attached to the core wire 10.
