摘要：
The utility model relates to medicine, namely to endobiliary minimally invasive interventional surgery and can be used for position correction percutaneous transhepatic external drainage catheter at their proximal migration in the surgical treatment of obstructive jaundice different nature. The object of the utility model is to increase reliability reposition percutaneous transhepatic external drainage catheter at their proximal migration of the bile duct, the reduction time of the repositioning of said catheter, and also reducing the risk of traumatizing the liver parenchyma. Technical result is a useful model: providing simultaneous execution reposition percutaneous transhepatic external drainage catheter and staining of bile ducts improving visualization of the working part of the tool during ultrasonography increased probability of returning percutaneous transhepatic external drainage catheter at its proximal migration of bile ducts to the initial position. This is achieved in that the utility model is a hollow rod rigidly connected to the working part of the tool which is in the form of steel wire and conically tapered in the distal direction. In the hollow rod provided with an opening for the injection of contrast into the channel of the liver parenchyma and bile ducts. From the junction of the hollow rod is applied with the working part ultrasonic notching. At the proximal end of a hollow rod connector disposed to a standard syringe.Полезная модель относится к области медицины, а именно к миниинвазивной эндобилиарной интервенционной хирургии и может использоваться для коррекции положения наружных чрескожных транспеченочных дренажных катетеров при их проксимальной миграции при хирургическом лечении механической желтухи различной природы. Задачей полезной модели является повышение надежности репозиции наружных чрескожных транспеченочных дренажных катетеров при их проксимальной миграции из желчных протоков, сокращение времени проведения репозиции указанных катет
