Description
Brief introduction: bile is inserted into the common bile duct through duodenoscope and bile is drawn from the nostril at the other end.
After prolonged immersion of bile and other liquids, it is not easy to break and degrade, the surface friction coefficient is low, and the inherent lubricity is low. The development effect is remarkable, and it can distinguish its position clearly in the process of dynamic use, and its performance is superior to that of the foreign products of the same kind.
Excellent springback recovery performance.
