ENDOSCOPIC LIGATION TOOL AND ENDOSCOPE

摘要

A method for ligating an internal body tissue using an outer cylinder member and an inner cylinder member including the processes of projecting the inner cylinder from a front end of the outer cylinder member; attaching a ligation band member to an outer peripheral surface of the inner cylinder member; contacting a front end of the inner cylinder member with an internal body tissue; suctioning an inside of the inner cylinder member via a channel communicated with the inside of the inner cylinder member such that the internal body tissue is drawn into the inner cylinder member; and ligating the internal body tissue with the ligation band member by disconnecting the ligation band member from the front end of the inner cylinder member when the inner cylinder member is drawn into the inside the outer cylinder member at a position where the ligation band member is disconnected.
