| titleOfInvention | Full-film-covered sampling biliary tract metal stent |
| abstract | The utility model provides a full tectorial membrane biliary tract metal support of can taking a sample, include: a stent body and a retrieval line; the stent body is formed by weaving nickel-titanium alloy wires and is in a grid shape; the two ends of the bracket body are spherical, and the body part is cylindrical; the inner surface and the outer surface of the two ends of the bracket body are respectively covered with a silica gel film, and the inner part and the outer part of the body part of the bracket body are discontinuously covered with the silica gel films; the body part is provided with a strip-shaped exposed area with a longitudinal walking shape; the recovery wire is an annular metal wire and is led out through the alloy wire at the tail end of the bracket body. The utility model can be completely placed in the common bile duct or cross the duodenal papilla, is used for supporting benign and malignant stricture of the bile duct, does not damage the seal of the common bile duct, and has low probability of generating support blockage and reflux cholangitis after operation; the head end of the completely released bracket body is spherical, so that the bracket can be prevented from shifting; tumor tissue can grow into the stent through the denuded zone; the metal bracket can be taken out by pulling the recovery wire, and a value sample can be reserved in the bracket cavity. |
