Claim Text:
1. A ligator for ligating one or more body ducts in a body cavity, the ligator comprising: a tubular member and a string member for bringing the body ducts close to a front-end portion of the tubular member, the string member being folded at a folding portion defining a first string and a second string of the string member, wherein the tubular member has an inner diameter allowing the first string and the second string of the string member to be inserted therethrough and has length extending from a ligating position of the body ducts in the body cavity to an outside of the body cavity, the string member has length equal to or larger than a double of the length extending from the ligating position to the outside of the body cavity, and the folding portion of the string member is in a tape form and has a width that is ranged from 3 mm to 7 mm, and a holding instrument that is configured with a rod and a hook-like section, the rod being linear and the hook-like section being in an arch shape and connected to the rod at a leading portion of the rod, wherein the arch shape is defined with three points, an opening portion is formed between the distal point and the rod with a gap, the gap is smaller than a thickness of the tubular member, the thickness being defined by a half difference between inner and outer diameters of the tubular member, the distal portion futher includes an extension that is liner extending from the distal point, the extension being formed by folding the hook-like section one time at the distal point, and the extension substantially lies in the vertical direction with respect to the rod.
