FORCEPS PLUG FOR ENDOSCOPE

摘要

PROBLEM TO BE SOLVED: To provide a forceps plug for an endoscope having good sealability when a treating implement is drawn out and an internal contaminant liquid hard to leak even when a biopsy forceps or the like is inserted or removed. SOLUTION: A first enclosed film 14 to be pushed and opened elastically by the treating implement normally maintained in a closed state by its own elasticity and passing there and a second enclosed film 26 closely contacted with the outer surface of the passing implement to seal there are disposed separately at 2.5 times as long as the diameter of a treating implement inserting channel 3 between both the films 14 and 26 with the film 26 used as an inlet side.
