ABSTRACT:
An endoscope unit includes an endoscope having an insertion portion and a fluid supply instrument mounted on the insertion portion. The fluid supply instrument comprises a thin resilient tube. This resilient tube is intimately attached to an outer periphery of the insertion portion of the endoscope and radially expansible. A supply member is connected to a basal end of the resilient tube. When fluid from this supply member is supplied to the basal end of the resilient tube, the resilient tube is radially expanded and a fluid passage is formed between the resilient tube and the insertion portion of the endoscope. The fluid is discharged from a distal end of the resilient tube.
