Abstract
The invention discloses a double-pigtail stent placed in the left hepatic duct of a human body. The double-pigtail stent comprises a middle tube and pigtail tubes at the two ends. The pigtail tubes at the two ends are located in two planes which are perpendicular to each other. The pigtail tubes at the two ends are respectively provided with one or more drainage holes. The pigtail tubes at the two ends comprise the upper-end pigtail tube and the lower-end pigtail tube and the lower-end pigtail tube deflects by ninety degrees towards the left or towards the right relative to the upper-end pigtail tube. According to the double-pigtail stent, a deflection angle exits between the upper-end pigtail tube and the lower-end pigtail tube, therefore, when the double-pigtail stent is used for the left hepatic duct, the pigtail tubes at the two ends are staggered by 90 degrees, the pigtail tube at the near end is prevented from making contact with the intestinal wall and injuring the intestinal wall, the complications such as intestinal wall bleeding or perforation are avoided and the surgical risk is lowered. Thus, the stent is more fit for the organs of the human body and can better play the role in drainage and meanwhile, the stent can be located in the lumen of the human body easily.
