介绍了一种门腔分流器械，包括子、母两个钕铁硼永磁体和介入操作器械。它基于磁压榨技术原理，通过介入途径分别将子、母磁体置入门静脉和下腔静脉，子母磁体自动对位相吸后压榨门静脉壁和下腔静脉壁。两周后，在二次介入操作下将子母磁体取出，门腔分流道即建立。主要用于门脉高压症微创分流手术。优点是介入下操作，门腔分流道建立后体内不存留任何异物，分流道可保持长期通畅，而且分流道口径不会扩张，可降低肝性脑病发生率。

A device of extrahepatic portacaval shunt is introduced. This device is composed of the daughter and parent magnets and the vascular interventional operation equipment. It is based on the principle of magnetic compression technology, through the intervention approach the daughter and mother magnet are moved to the portal vein and inferior vena cava, respectively. Then the two magnets attract and compress the vessel walls of portal vein and inferior vena cava. Two weeks later, the magnets are detached from the vessel wall with a RUPS-set and the portacaval shunt is established. It is mainly used for the treatment of portal hypertension. It belongs to the interventional operation, there is no any foreign body remaining after the portacaval shunt is established, which can maintain long-term patency. Futhermore the portacaval shunt will not be expanded. therefore it can significantly reduce the incidence of hepatic encephalopathy.
