Medical shunt device for portal hypertension

Abstract

A medical shunt device for portal hypertension mainly consists of a shunt device, a catheter and a catheter connecting part. The shunt device consists of a bottom support, an upper cover and a silicon cushion; the bottom support is a circular structure, and a hollow boss is arranged in the bottom support; two catheter holes are arranged on the wall of the boss; a plurality of fixing holes are arranged on the lower portion of the bottom support; the upper cover is arranged on the upper portion of the boss; a middle hole is arranged on the upper cover; the silicon cushion consists of an upper small circular truncated cone and a lower large circular truncated cone; the small circular truncated cone can be embedded in the middle hole of the upper cover; the small circular truncated cone of the silicon cushion can be embedded in the middle hole of the upper cover from the lower portion of the upper cover; and the lower edge of the large circular truncated cone of the silicon cushion is higher than the catheter holes, and a cavity is formed in the boss. One end of the catheter connecting part is fixedly connected with the catheter holes in the shunt device; and the other end of the catheter connecting part is connected with the catheter. A plurality of side holes are arranged at one end of the catheter so as to prevent thrombus. A complex TIPS (transjugular intrahepatic portosystemic shunt) intervention means is changed into simple and feasible percutaneous puncture technology, surgery time is shortened, and burden on a patient is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a medical shunt device for portal hypertension. Background technique [0002] Most patients with advanced liver cancer will be accompanied by symptoms of liver cirrhosis. In the decompensated stage of liver cirrhosis, portal hypertension is often manifested: repeated rupture of esophageal and gastric varices, and intractable hydrothorax and ascites, which seriously endanger the life of the patient. [0003] At present, the common method of treating the above-mentioned portal hypertension is to use TIPS interventional surgery, which is: using guide wire and catheter technology, inserting a metal stent between the intrahepatic portal vein and the hepatic vein to establish a shunt channel to reduce The pressure of the portal vein, thereby preventing and reducing the possibility of a series of complications such as gastrointestinal bleeding caused by portal hypertension. ...

AI Technical Summary

Problems solved by technology

In this process, first of all, the puncture needle must enter the body through the catheter, from the jugular vein to the hepatic portal vein, and the passage in the body will pass through the atrium, which is highly risky during the operation; The time is generally very long, resulting in a very long operation process; moreover, a large amount of medical equipment is required to complete the entire operation, and the operation cost is high. Generally, one operation costs 30,000 to 40,000 yuan

Due to the difficulty, risk and cost of TIPS interventional surgery, there are few hospitals in China that can perform this technology
