The utility model relates to medical instrument technical field especially, and it is a kind of covered stent and implantation system.This covered stent includes support framework and film, wherein: support framework is the hollowed out cylinder structure of peripheral surface, it can be radially compressed and expand;Film is coated on part support framework, and drainage mesh is formed at the region of support framework not being coated by film.Due to film being coated on part support framework, drainage mesh is formed at the region of support framework not being coated by film, bile of gallbladder, bile in common hepatic duct and pancreatic juice in pancreatic duct can enter the inside of covered stent through drainage mesh and reach duodenal papilla, thereby avoiding the phenomenon that bile and pancreatic juice cannot flow out from common bile duct and reach duodenal papilla due to common bile duct being pressed by stent, and simultaneously, a plastic stent does not need to be additionally implanted in common bile duct to help common bile duct drainage, to achieve the purpose of reducing operation cost and operation complexity.

This invention discloses an intelligent monitoring and repair system for gastrointestinal anastomoses, relating to the fields of medical devices and biomedical engineering technology. The system includes a bioresponsive sealing adhesive, an intelligent drainage catheter, and an external intelligent terminal. The sealing adhesive covers the surface of the anastomosis and releases colorimetric and fluorescent signals under the action of gastric, intestinal, or pancreatic juice. The intelligent drainage catheter has a main drainage chamber, a pneumatic monitoring chamber, an optical conduction channel, and a perfusion chamber, with an anti-adhesion cage at its tip. The external intelligent terminal is used for optical detection and vacuum attenuation determination. This system can achieve local sealing of the anastomosis, identification of abnormal signals, and monitoring of catheter status.

The application relates to the technical field of a biliopancreatic chronic disease remote cooperative management system, and particularly discloses a biliopancreatic chronic disease remote cooperative management system. The system comprises a medical image data acquisition unit, an individualized anatomical model construction unit, a biliopancreatic fluid dynamics simulation engine, a virtual intervention simulation unit, a risk early warning analysis unit and a remote cooperative diagnosis and treatment platform; a digital twin model of a biliopancreatic duct system of a patient is constructed, the biliopancreatic fluid flow state is simulated in combination with computational fluid dynamics, and virtual stent implantation and other intervention effect pre-performance are supported, so that identification of occult obstruction and quantitative evaluation of a treatment scheme are realized; the system also supports multi-territory expert cooperative consultation, dynamic model updating and risk grading early warning. Through the technical scheme, a leap from morphological diagnosis to functional diagnosis is realized, and early lesion detection rate, individualized diagnosis and treatment level and remote cooperation efficiency are improved.
