Percutaneous transhepatic gallbladder direct puncture drainage tube

Abstract

The invention provides a percutaneous transhepatic gallbladder direct puncture drainage tube, and belongs to the technical field of medical device manufacturing. The direct puncture drainage tube includes a drainage tube body 1, a supporting tube 2 and a needle core 14; the supporting tube 2 is placed in the drainage tube body 1, the needle core 14 is placed in the supporting tube 2, and the tailpart of the drainage tube body 1 and the tail part of the needle core 14 are connected to the tail part of the supporting tube 2; and a channel in a tapered tube 3 located on the top of the drainage tube body 1 is tapered, the concave part of the outer surface of a concave tube 4 located on the upper part of the drainage tube body 1 is provided with a balloon 5, a water injection channel 6 arranged in the balloon 5 is connected with a connector 7 arranged at the tail part of the drainage tube body 1, and the part, located between the tapered tube 3 and the concave tube 4, of the drainage tubebody 1 is provided with a side hole 8. The drainage tube achieves the beneficial effects of less damage, fewer complications, simple operation, a simplified operation process, and saved operation timeand medical costs.

Description

technical field [0001] The invention belongs to the technical field of medical device manufacturing, and relates to a percutaneous transhepatic gallbladder direct puncture drainage tube. Background technique [0002] Gallstones are a common disease that can induce acute cholecystitis, chronic cholecystitis, and even gallbladder cancer. The traditional treatment for gallbladder stones complicated with cholecystitis is open cholecystectomy, and with the development of minimally invasive techniques today, laparoscopic cholecystectomy has become the gold standard for the treatment of gallbladder stones. With people's emphasis on gallbladder function and protection, gallbladder-preserving gallstone removal surgery was born. The surgical methods have experienced gallbladder-preserving surgery through small right upper quadrant incision, laparoscopic-assisted gallbladder-preserving surgery through small right upper quadrant incision, and complete laparoscopic gallbladder-preserving...

AI Technical Summary

Problems solved by technology

The tip of the drainage tube with a thinner outer diameter is easy to pull to form a loop, but it is more difficult to form a loop with a thicker drainage tube. Therefore, the drainage tube for gallbladder puncture above 14Fr is mostly linear, and lacks a loop, which is prone to displacement and come out

In addition, during the puncture and catheterization process, tearing and bleeding may occur at the gallbladder puncture point, and the compression effect of the drainage tube is poor
