Description

Bed side door body part flow arrangement

Technical field

The present invention relates to technical field of surgical instruments, in particular to a kind of side door body part flow arrangement.

Background technique

There is Portal hypertension in end-age cirrhosis patient, esophageal varices cause alimentary canal (oesophagus, Stomach) big bleeding be patient major causes of death.Sengstaken-Blakemore tube compression hemostasis is that traditional treatment gastroesophageal varices are bent The compression hemostasis of tension fracture bleeding, but success rate of hemostasis is low, painful.In recent years, as Emergency Endoscopy clinic is answered With going deep into for research, scope ligation adds cirso- extension injection of tissue binder of the low dose of curing agent again at stomach bottom It is proved to that there is preferable haemostatic effect, but for the patient of massive hemorrhage of gastrointestinal tract, since amount of bleeding is too big, the visual field is unclear in short-term It is interior to be difficult to find bleeding position accurately and stop blooding；No matter Sengstaken-Blakemore tube hemostasis by compression or gastroscope lower hemostasia are all without reducing portal vein Pressure cannot effectively stop blooding, easily occur rupture haemorrhage again.

Through this Toluidine blue O technology of jugular vein liver inside door vena systemica bypass (TIPS) introduce it is clinical since, at For a kind of primary treatment selection for currently controlling portal hypertension bleeding and difficultly curing ascites, divide through jugular vein liver inside door vena systemica Stream art needs determine operating time according to patient body situation and need to do the work of a large amount of Preoperative Method, need number at As carrying out under angiography machine (DSA), operating time is long, can not be operated by bed；Therefore alimentary canal is gone out greatly The emergency case TIPS of blood is simultaneously not suitable for, and currently still mainly takes traditional Sengstaken-Blakemore tube hemostasis by compression for such patient And gastroscope lower hemostasia scheme emergency, if life danger will likely occur in hemostasis failure, patient.
