Problems solved by technology

The above-mentioned treatment plan has the following disadvantages: 1. Endoscopic balloon compression for hemostasis can only be performed under endoscopy, and the duodenal papilla is compressed for a short time, which can only play a temporary hemostasis role. Risk of duodenal papilla hemorrhage; 2. Duodenal papillary edema after endoscopic hemostasis injection can easily lead to stenosis of the pancreatic duct opening and induce acute pancreatitis; 3. Endoscopic hemostatic clamp clamp hemostasis is effective for active bleeding Good hemostatic effect, but when the nipple is actively bleeding, the blood is easy to contaminate the duodenoscope lens, resulting in unclear food under the endoscope, and it is difficult to perform precise clamp hemostasis; 4. The hemostatic effect of interventional embolism is relatively obvious, but Branch organ ischemia is prone to occur after arterial embolization, resulting in impaired ischemic pain function, among which liver function damage and cholestatic cirrhosis are common early and late complications after interventional embolization

Abstract

The invention discloses an external biliary drainage tube for preventing duodenal papilla hemorrhage and an implantation device thereof. The external biliary drainage tube for preventing duodenal papilla hemorrhage comprises a straight tube, a first drainage tube section, a second drainage tube section, a third drainage tube section and a fourth drainage tube section which are communicated in turnby a lumen. The straight pipe comprises a head end, a first straight pipe section and a second straight pipe section, wherein the head end is communicated with the lumen in turn; an upper end of thehead end is open, and a low end is provided with a head end through hole; the outer wall of the first straight tube section is sleeved with a balloon. The balloon was placed in the duodenal lumen andthe tension of the first drainage tube segment (spiral tube) was maintained by the drainage tube fixator, which could exert continuous pressure on the bleeding duodenal papilla and avoid the occurrence of acute pancreatitis caused by duodenal transient compression. To prevent the internal and external movement of the external biliary drainage tube to prevent the bleeding of the duodenal papilla through the balloon and the drainage tube fixator.

Description

technical field [0001] The invention relates to a drainage tube and its insertion device, in particular to an external biliary drainage tube and its insertion device for preventing duodenal papilla hemorrhage. Background technique [0002] Choledocholithiasis is a common and frequently-occurring disease in my country. Blockage of the common bile duct by stones can induce complications such as acute cholangitis, obstructive jaundice, and acute biliary pancreatitis. Symptoms include chills, fever, abdominal pain, and jaundice. Cause shock, long-term calculus stimulation has the risk of cholangiocarcinoma, which is an important disease that endangers human health. The current treatment options for choledocholithiasis include laparoscopic biliary exploration, laparoscopic biliary exploration, endoscopic retrograde cholangiopancreatography (ERCP) + stone extraction, percutaneous transhepatic cholangiocentesis (PTCD) + fistula dilation + percutaneous transhepatobiliary Tractoscopy...
