摘要：
A ligating apparatus and method. One embodiment includes a barrel-shaped ligator attached to the penetrating end of a structure, such as an endoscope, and cord pulling assembly at the opposed end of the structure. In the case of use with an endoscope, a pullable cord is wound on the cord pulling assembly and then extends through a working channel in the endoscope to penetrate the ligator. The barrel-shaped ligator is coaxial with the penetrating end of the endoscope, and a practitioner can look through the operating end of the endoscope and see through the endoscope and ligator to observe flesh, for example, in front of the ligating end of the ligator. The ligator includes coaxial inner and outer barrels that rotate with respect to each other upon pulling of the cord by the cord pulling assembly. This relative rotation causes one barrel to move laterally with respect to the other barrel and eject a ligature from the ligating end of the ligator. The cord pulling assembly is mounted and held in place on the endoscope by opposed arcuate arms and a transverse removable pin.
