Abstract
Abstract An endoscope with a device for raising a medical instrument, comprising an operating section and an insertion section having a distal end portion. A storage room having an opening is provided in a distal end portion and a channel duct communicating with the storage room is located in the insertion section. A medical instrument raising block, mounted in the storage room, serves to raise the distal end portion of the medical instrument which, after passing through the channel duct, extends from the opening. A raising operation wire runs through the passageways of the operating section and the insertion section and the distal end of the wire is attached to the medical instrument raising block. A device for preventing the medical instrument from being caught by the wire is formed at the top of one side wall, very close to the wire, of the side walls defining the storage room.
