LIGATION DEVICE

PURPOSE:To facilitate an operation and to decrease the burden on a patient by constituting the above device in such a manner that even the ligating section having the difficulty in looping can be easily ligated from the outside of the body. CONSTITUTION:After a curved part 2a at the front end of an introducing part 2 is detained to the ligating section 10, a soft introducing body 6 is inserted into the introducing passage of the introducing part 2. Yarn for ligation is inserted and detained via a knot 7b into the introducing body 6 and is guided to the introducing passage. This yarn bypasses the object section 10 by the curved part 2a and its front end projects to be inserted into a receiving passage 3b, from which the yarn is led out to the outside. The projected introducing body 6 is removed in this way. The loop of the yarn for ligation for the section 10 is gradually narrowed when the loop part 7 for yarn knotting returns to the object section 10 side at the rear end of the introducing body 6. The object section 10 can be ligated from the outside of the body by relatively pulling the yarn for ligation.
