摘要： PROBLEM TO BE SOLVED: To provide a clip device for an endoscope capable of positively and easily performing multi-way clipping for wrapping a diseased part by providing a clip with three or more arm parts, and opening/closing them in a stable state with light operating force. SOLUTION: The clip 1 is provided with at least three arm parts 1a opened and closed in a nearly uniform direction without intersecting one another. A core metal 9 internally contacting each arm part 1a inside an opening/closing drive part 1c in the open state of the clip is inserted and arranged in the clip 1, and a frictional resistance reducing part 9b is provided for reducing frictional resistance between the clip 1 and at least one of a clip closing ring 6 and the core metal 9 in the middle of opening/closing operation of the clip 1.

摘要： PROBLEM TO BE SOLVED: To provide a clip device for an endoscope enabling a treatment tool to be smoothly passed through a treatment tool channel in the endoscope without being damaged, even if the channel is curved with a small radius of curvature, by making it possible to reduce the length of a hard end portion. SOLUTION: In the clip device for an endoscope, a clip 2 is opened or closed forward by being drawn into a clip closing ring 6, and is then held closed. The clip 2 is curved so that its portion close to the tip of an arm part 2a points backward when the clip is in a setting state prior to opening or closing when it is drawn into the clip closing ring 6.

摘要： PROBLEM TO BE SOLVED: To provide a clip device for an endoscope capable of internally washing the water feed channel arranged in a flexible sheath uniformly and easily over the total length thereof by brushing. SOLUTION: The clip device for the endoscope is constituted so that the clips 11 and 12 arranged to the leading end of the flexible sheath 2 are separably connected to the leading end of the operating motion transmitting member 4 inserted and arranged in the flexible sheath 2 so as to freely advance and retreat in its axial line direction to be held to a closed state by the pulling operation of the operating motion transmitting member 4 from the operation part 20 connected to the base end of the flexible sheath 2 and the clips 11 and 12 held to the closed state are separated from the flexible sheath 2 and the operation wire 4. The water feed channel 4a is formed in the operating motion transmitting member 4 over the total length thereof so as to pierce through the member 4 axially and both ends 41 and 42 of the water feed channel 4a are straightly opened axially.
