Abstract
A ligation apparatus includes an opening portion at a front end of a rod, in communication with the front end side, the left side, and the right side, having a cross section of substantially a U-shaped configuration in the direction of axis of the rod, and a mobile unit in the opening portion. The mobile unit includes a body held in a movable manner, and a thread supporting unit having the tip end protruding from the opening portion for supporting a ligature at the front end. The ligature has one end tied to the thread supporting unit of the mobile unit, and the other end translated downwards from the upper side of the mobile unit according to a predetermined direction of rotation, whereby a knot of the ligature is formed. Therefore, a ligation site can be ligated extracorporeally even if the hole puncture in a somatic layer is small.
