OBJECTIVE
To design and develop a disposable superfine catheter system for visual examination of bile and pancreatic ducts and predict its clinical application value.
METHODS
The superfine triple-lumen catheter and miniature photography technology were used to design and produce a disposable superfine catheter for visual examination of bile and pancreatic ducts, and animal experiments were conducted to compare said catheter and SpyGlass™.
RESULTS
The designed and developed disposable superfine catheter for visual examination of bile ducts with a diameter of 2.4 mm could enter the third-order and fourth-order bile ducts in the animal liver and also the gallbladder via the cystic duct for observation. The said catheter has a water injection rate of 0.8 mL/s, 0.16 megapixels, a resolution of 400 × 400, a depth of field of 0.3 to 20 mm, and a tilting up angle >90°.
CONCLUSION
The new disposable catheter for visual examination of bile ducts has a superfine diameter, easier operation, and clearer imaging, and is expected to have a higher clinical practical value.
目的
设计并研发一种用于胆管和胰管可视检查的一次性超细导管系统，并预测其临床应用价值。
方法
采用超细三腔导管及微型摄像技术，设计制作一种用于胆管可视检查的一次性超细导管，并进行动物实验，将该导管与SpyGlass™进行比较。
结果
所设计研发的用于胆管可视检查的一次性超细导管直径为2.4 mm，可进入动物肝脏的三级和四级胆管，还可经胆囊管进入胆囊进行观察。该导管注水速度为0.8 mL/s，像素为0.16兆，分辨率为400×400，景深为0.3至20 mm，上倾角>90°。
结论
新型一次性胆管可视检查导管直径超细，操作更简便，成像更清晰，有望具有更高的临床实用价值。
