PURPOSE: A tubular organ expansion type pusher is provided to simplify a tubular organ fixing process, thereby rapidly and easily performing an anastomosis process of a tubular organ. CONSTITUTION: A head(12) is inserted to the inside of a tubular organ through one side of the opened tubular organ. A pusher comprises one or more expansion members(22). The expansion member moves the tubular organ to an expansion position for expanding the tubular organ by pressurizing the inner wall of the tubular organ. An opening part(14) for accessing one end of the expansion member is included in the head. The expansion member includes a guide surface moving along one surface of the head. The pusher comprises a connection bar which enables the expansion member to rotate. |
