An articulated T tube has been devised to simplify percutaneous replacement. Because the crosspiece and the stem are held together with sutures, they can be aligned over a catheter and guide wire for atraumatic insertion into the bile duct. By pulling the suture taut, the articulated T tube is easily reconstituted. A second suture can be attached to the proximal limb of the crosspiece to extract it end-on at a latter date without enlarging the tract. This articulated tube has been found very useful for safely replacing T tubes that have fallen out of immature tracts (n = 2) and inserting T tubes in tumor-encased bile ducts either via an existing T-tube tract (n = 1) or transhepatically (n = 1). This design extends the usefulness of T tubes for efficient intra- or extrahepatic bile duct drainage.
一种可弯曲的T形管已被设计出来，以简化经皮置换。由于横档和杆部通过缝线固定在一起，它们可以在导管和导丝上对齐，以便无创伤地插入胆管。通过拉紧缝线，可弯曲的T形管很容易重新组装。可以在横档的近端肢体上连接第二根缝线，以便日后将其端部拔出，而无需扩大通道。这种可弯曲的管子已被发现对于安全替换从未成熟通道脱出的T形管（n = 2）以及通过现有的T形管通道（n = 1）或经肝（n = 1）在肿瘤包裹的胆管中插入T形管非常有用。这种设计扩展了T形管在肝内或肝外胆管有效引流方面的用途。
