In practice, the free end of the ligature is brought around to encircle a tissue and passed through a conduit within the buckle portion of the ligature, much as one threads a belt end through a buckle prior to cinching tight and fastening. The buckle portion preferably has a tab projecting therefrom with a hole therein which accommodates the buckle grasping member on the end of the outer member. The buckle grasping member is preferably a post or stationary pin which is inserted into the hole in the tab on the buckle portion. The free end of the end of the ligature has a special site for receiving and releasably engaging the free end grasping portion (fork) of the tool. A…
