Title:
CLEANING TOOL FOR TUBULAR PASSAGE IN ENDOSCOPE, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2016/035582
Kind Code:
A1
Abstract:
Provided are: a cleaning tool for a tubular passage in an endoscope, whereby it becomes possible to strongly and stably fix an elastic porous member even when a high contact pressure is applied to the elastic porous member; and a method for manufacturing the cleaning tool.
The cleaning tool 10 can be inserted into a tubular passage in an endoscope to clean the tubular passage. The cleaning tool 10 is equipped with a core wire 20 which is made from a metal, a resin tube 30 which covers the outer periphery of the core wire 20, and a cylindrical elastic porous member 40 which is arranged over the outer periphery of the resin tube 30, wherein the resin tube 30 and the elastic porous member 40 are respectively made from resin materials which can be integrally fused to each other. The method for manufacturing the cleaning tool 10 comprises: applying a high-frequency electric current to a heating coil which is arranged on the outer periphery of the resin tube to heat the core wire 20 through high-frequency-induced heating, thereby integrally fusing the resin tube 30 to the elastic porous member 40.
