TUBE ASSEMBLY FOR USE IN BILE DRAINAGE AFTER BILIARY SURGERY

摘要

A drainage tube assembly for use in a bile drainage after biliary surgery has a flexible drainage tube having a distal end and a proximal end. The drainage tube has an outer diameter capable of being inserted into the common bile duct via the cystic duct. A handling block provided at the distal end of the drainage tube defines a first passage and a second passage branched from the first passage. The first passage is communicated at its one end with the distal end of the drainage tube. The second passage is connected with a side tube. In particular, a metal sleeve is secured around the drainage tube so that a part of the drainage tube covered by the metal sleeve still maintains an original inner diameter thereof.
