ENDOSCOPE GUIDE STENT

摘要

The purpose of the present invention is to provide a technology to guide the movement of an endoscope to a position desired by an operator in an inner cavity formed as a diameter in which the endoscope is hard to move in inner cavities having different diameters in the body. The present invention relates to an endoscope guide stent. The endoscope guide comprises: a first body unit having a hollow cylindrical shape and a second body unit having a hollow cylindrical shape having a different diameter from the diameter of the first body unit at one end of the first body unit. Further, the first body unit further comprises a moving prevention unit to prevent the slip of the first body unit by being formed with an expanded diameter than the diameter of the first body unit at the other end of the first body unit. Herein, the moving prevention unit is formed to have an increased diameter when the moving prevention unit moves from the other end of the first body unit in the direction of an end unit. Accordingly, the endoscope guide stent can guide a moving path of surgical instruments such as the endoscope and the like by locating the first body unit and the second body unit, which have a different diameter, on inner cavities having different diameters in the body.
