| titleOfInvention | A kind of hepatic portal blood flow blocking device |
| abstract | The invention discloses a hepatic portal blood flow blocking device, which relates to the field of clinical medicine and comprises a catheter, a blocking bag and a positioning head. The base end of the catheter is provided with a protective plug to block external impurities from entering the catheter; At least one layer of flexible layer material, the inner surface of the flexible layer or the flexible layer is provided with spaced linear support frames, the support frames are made of shape memory alloy; the flexible layer surrounds the interior to form a cavity; the end of the cavity A section of protrusion away from the catheter forms the positioning head, the center of the positioning head is provided with a pinhole type through hole to connect the outside with the cavity, and the positioning head is also covered with an annular positioning ring. It can reduce the requirements for ultrasonic guidance technology and puncture technology during use, and realize simple and rapid blood flow blocking in the hepatic portal vein, so as to implement accurate resection. The technical effect of reducing the chance of portal vein metastasis and improving the postoperative perioperative survival rate of patients. |
