LIGATOR AND LIGATION METHOD
[Problem] To provide a ligator for ligating body duct(s), said ligator enabling quick, easy and damage-free repetition of ligation and release of one or more body ducts in a body cavity through an operation outside the body cavity, and having an excellent performance of blocking the flow of a body fluid such as blood or lymph in a body duct. In an abdominal surgery, the ligator can be provided at such a position as not disturbing the surgery per se or hindering the vision during the surgery, while leaving the back-end thereof outside the body cavity, and can be operated outside the body cavity. In an endoscopic surgery, the ligator can be inserted from an opening that is a surgical wound, while leaving the back-end thereof outside the body cavity, and can be operated outside the body cavity. [Solution] A ligator (1) for ligating one or more body ducts (2) in a body cavity (3), said ligator comprising a tubular member (11) allowing the insertion of at least two string members (12) therethrough and the string members (12) for bringing a body duct (2) close to the fore-end of the tubular member (11).
