Embodiment Construction

[0024] An anti-reflux biliary-intestinal stent, comprising a tubular intestinal stent 1 and a biliary stent 2, the inlet of the intestinal stent 1 is detachably connected to the outlet of the biliary stent 2, and the outlet of the intestinal stent 1 is provided with an anti-reflux regurgitated petal body 11;

[0025] The petal body 11 is in the shape of a flower bud to be placed, and includes several petal sheets 111 stacked along the circumference of the intestinal support 1. The fixed end of the petal sheet 111 is fixed on the end surface of the exit of the intestinal support 1. The free ends of the two are inclined towards the center of the intestinal support 1, and the adjacent petals 111 are pressed together to form an outwardly protruding airtight petal body chamber at the exit of the intestinal support 1.

[0026] The outlet end of the intestinal stent 1 extends around to form a mounting surface 12 perpendicular to the intestinal stent 1 , and the fixed end of the petal...

Abstract

The invention provides an anti-regurgitation gallbladder-intestine stent.The anti-regurgitation gallbladder-intestine stent comprises a tubular intestine stent body and a tubular biliary stent body.An inlet of the intestine stent body is detachably connected with an outlet of the biliary stent body.An outlet of the intestine stent body is provided with an anti-regurgitation petal.The petal is in a to-be-bloomed flower bud shape and comprises multiple petal pieces stacked in the circumferential direction of the intestine stent body.The fixed ends of the petal pieces are fixed to the end face of the outlet of the intestine stent body.The free ends of the petal pieces obliquely draw together towards the center of the intestine stent body.The adjacent petal pieces are in press fit, and an outwards-protruding airtight petal chamber is defined at the outlet of the intestine stent body.The anti-regurgitation gallbladder-intestine stent is easy to operate, high in success rate and small in trauma, the petal can only bloom forwards to form an outlet, gallbladder-intestine regurgitation can be effectively prevented, and regurgitation cholangitis is effectively reduced.

Description

technical field [0001] The invention relates to an anti-reflux biliary and intestinal support. Background technique [0002] At present, manual suture is mainly used in biliary-enterostomy surgery, that is, the operator uses traditional surgical methods, and then uses needle holders, tweezers, and needles and threads to perform manual ligation. Risk of retrobiliary fistula. In addition, due to the defect or absence of the duodenal papilla sphincter, it is easy to cause postoperative reflux cholangitis. For beginners or those with poor suturing skills, biliary-enteric anastomosis is often unable to be successfully completed, and biliary plastic stents are chosen by most patients and their families because of their low price. The short-term status quo often plagues us. [0003] Reflux cholangitis, also known as ascending cholangitis, is caused by retrograde infection of intestinal bacteria. In addition to biliary enterostomy, reflux of intestinal contents into the biliary ...
