Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a biliary tract contrast agent injection device through a T tube.
Background
Since the age of 70, cholangiography is used as an auxiliary diagnosis and treatment technology before, during and after the biliary tract diseases, and the efficiency of diagnosis and treatment of biliary tract diseases is greatly improved. For a long time, the X-ray examination is an important examination method for biliary diseases, but some biliary diseases cannot be clearly developed on a common X-ray film, and at the moment, the biliary tract contrast technology can solve the problems.
The current biliary tract radiography method which is most commonly used in clinic is direct biliary tract radiography with accurate development and high efficiency, and comprises Endoscopic Retrograde Cholangiopancreatography (ERCP), intraoperative biliary tract radiography (IOC), Percutaneous Transhepatic Cholangiography (PTC) and T-tube angiography (T-CG). However, these direct biliary tract imaging methods all require that the doctor exposes to X-ray fluoroscopy and injects the contrast agent directly into the patient's biliary tract via different routes, and despite protective measures such as lead clothes, the high-intensity workload is accompanied by high-density ray contact frequency, which still causes a certain iatrogenic radiation damage to the doctor, threatening the health of the doctor; magnetic resonance pancreaticocholangiography (MRCP), a non-invasive magnetic resonance imaging technique that can display the cholepancreatic duct system without a contrast medium, has been widely used in clinical practice in recent years, but it is expensive, not suitable for patients with internal metal stents, metal dentures, etc., who may interfere with the magnetic resonance effect, and cannot perform therapeutic procedures, so it cannot replace direct cholangiography. The medical teams at home and abroad try to design remote injection equipment (such as BerkeRalph and the like) or use the existing remote injection technology to replace doctors to carry out the biliary tract radiography operation, but the structure of the equipment mostly does not meet the biliary tract radiography requirement, the equipment is horizontally designed, and has no bubble pumping action and can not well simulate the actual biliary tract radiography process; in the traditional contrast medium injection process, doctors mostly operate to 'push blindly' by hand feeling, the speed is poor in controllability, the pushing speed is high, the pressure in the biliary tract is easy to suddenly rise, and symptoms such as abdominal distension, abdominal pain and cholangitis are caused. In conclusion, a device for injecting a biliary tract contrast agent through a T tube, which can be remotely controlled, can highly restore the biliary tract contrast agent injection process and can control the speed to change, is urgently needed in clinic.
