Description

Sacculus hemostasis drainage tube of bile pancreatic duct

Technical Field

The utility model relates to a surgical instrument for digestive system department, in particular to a hemostatic drainage tube used when a common bile duct and a pancreatic duct bleed.

Background

Biliary hemorrhage is a serious complication of biliary diseases and post-biliary surgery, and is also a common cause of upper gastrointestinal hemorrhage. The same is true of pancreatic duct bleeding. Both can be severely life threatening. Patients may develop bile or pancreatic duct bleeding either as a result of the disease itself, trauma, or during or after an ERCP (retrograde cholangiopancreatography) procedure. However, biliary tract bleeding and pancreatic duct bleeding have the huge problem of difficult hemostasis under the limitation of the current technical means. Because of the inability to achieve endoluminal hemostasis, current methods are primarily surgical or DSA contrast embolization. The operation trauma is large, the recovery of the patient is slow, the bleeding part of DSA contrast embolization is difficult to find, and the success rate of the operation is limited. Therefore, the invention is needed to provide a device capable of achieving compression hemostasis in the bile duct or pancreatic duct to fill the technical gap.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and solve the difficult problem of hemostasis in the bile duct or the pancreatic duct.

In order to achieve the above object, the utility model provides a bile duct pancreatic duct sacculus hemostasis drainage tube, including the drainage tube that is used for penetrating biliary tract or pancreatic duct, the drainage tube is close to the head end position cover and establishes fixed hemostasis gasbag, the fill and discharge pipe of hemostasis gasbag along the drainage tube pastes and leans on fixedly.

Preferably, the side wall near the head end of the drainage tube is provided with dense drainage holes, and the hemostatic air bag is fixed by avoiding the dense drainage holes.

Preferably, the drainage tube is bounded by the hemostatic air bag, and the dense drainage holes are formed only in the area close to the head end.

The hemostatic air bag is used for plugging the fluid force of drainage, thereby achieving better drainage effect.

Preferably, the drainage tube is provided with a pigtail type head end and is used for occasions with large working space inner diameters.

Preferably, the tail end of the drainage tube is provided with a drainage socket for switching, and the tail end of the inflation and deflation tube is provided with an inflation and deflation socket for switching; the drainage plug-in connector is plugged into the pipeline inlet of the negative pressure drainage machine, and the inflation and deflation plug-in connector is plugged into the outlet of the inflation pipeline.

Preferably, the nasal cavity puncture catheter further comprises a nasal guide tube passing from the nasal cavity to the nasopharyngeal cavity; the tail end of the oral cavity end of the nasal guide tube is expanded and rounded, and openings for penetrating the drainage tube and the inflation and deflation tube are arranged on the side wall of the expanded and rounded part.

The beneficial effects of the utility model are that adopt a collection sacculus to press hemostasis and drainage bile or pancreas liquid pipe as an organic whole, can reach drainage bile, pancreas liquid, observe bile or pancreas liquid nature, can again appear biliary tract or pancreas pipe when bleeding in the discovery, oppress bile duct or pancreas pipe position of bleeding, reach the purpose of hemostasis by compression, observe the convenience in the use, easy and simple to handle, safe effective.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

According to the first embodiment of the saccule hemostatic drainage tube for cholecysts and pancreaticoses shown in fig. 1, the saccule hemostatic drainage tube comprises a drainage tube 1 for penetrating into the biliary tract or the pancreatic duct, a hemostatic air bag 2 is sleeved and fixed at a position of the drainage tube 1 close to the head end, and an inflation/deflation tube 3 of the hemostatic air bag 2 is attached and fixed along the drainage tube 1. The drainage tube 1 is bounded by the hemostatic air bag 2, and dense drainage holes 4 are formed in the side wall of the area close to the head end. The drainage tube 1 is provided with a pigtail type head end 5 (of course, a straight head type head end can be made as required to adapt to a narrow space).

According to a second embodiment of the saccule hemostasis drainage tube of the cholepancreatic duct shown in fig. 2, on the basis of the first embodiment, a drainage interface 11 for switching is arranged at the tail end of the drainage tube 1, and an inflation and deflation interface 31 for switching is arranged at the tail end of the inflation and deflation tube 3; the drainage socket 11 can be inserted into the inlet of the negative pressure drainage machine pipeline 12, and the inflation and deflation socket 31 can be inserted into the outlet of the inflation pipeline 32.

According to the third embodiment of the saccule hemostatic-drainage tube for cholecystokinis shown in fig. 3 to 5, on the basis of the second embodiment, the balloon hemostatic-drainage tube for cholecystokinis further provided with a nasal guide tube 6 which passes from the nasal cavity through the nasopharyngeal portion and the oral cavity; the end of the oral cavity end of the nose guiding tube 6 is enlarged and rounded, and an opening 61 for penetrating the drainage tube 1 and the inflation and deflation tube 3 (too small and not marked in the figure) is arranged on the side wall of the enlarged and rounded position.
