BILIARY STENT HAVING WINDING AND FIXING MEMBER AROUND WHICH PULLING STRING IS WOUND

The present invention relates to a biliary stent having a winding and fixing member around which a pulling string is wound, and more specifically, is characterized in that a biliary stent having a winding and fixing member around which a pulling string is wound allows a stent to pass through the skin and the liver of the human body so as to be inserted into a biliary tract at which a lesion has been formed, and then covers and fixes, on the skin surface, a winding and fixing member around which a pulling string, that is connected to and extended from the stent provided in the biliary tract and exposed to the outside of the human body, is wound, so that contamination of the pulling string, caused by an external environment, is prevented and the stent is prevented from moving in the biliary tract and leaving from the inside of the biliary tract, and comprises: the stent which has a cylindrical body having space parts formed by weaving a plurality of shape memory alloy wires with each other in a zigzag, and having a plurality of bent ends formed on both ends along the circumference thereof, and which has a strong knot part formed in order to maintain a firmly fixed state in which both ends of the pulling string are tied to not be easily loosened, so that surgery is performed with the pulling string exposed on the outside of the human body due to the long length thereof, and thus the cylindrical body is prevented from slipping inside the biliary tract, wherein the knot part is formed at the bent ends to have a gap enabling the cylindrical body to properly contract or unfold, the knot part is formed to have a short or long gap at the bent ends according to the diameter of the cylindrical body, and the cylindrical body is withdrawn while the circumference of the end thereof contracts toward the center thereof when the knot part is pulled from the outside of the human body during the removal procedure of the cylindrical body; the winding and fixing member which has a main body that includes an adhesive part so as to be adhered and fixed to the outer surface of the skin of the human body, and which is formed so that the pulling string is wound around the outer circumference of the main body; and a cover gauze member which covers all of the winding and fixing member and the whole skin surface of the human body that is adjacent to the winding and fixing member and which is adhered and fixed to the skin surface, in order to prevent the movement of the winding and fix
