Used for cannulation of the ductal system and for sphincterotomy, if preloaded, also aids ERCP operation in the stenosis of bile duct difficult stricture.
Tapered tip enables easy cannulation.
Insulating coating minimizes the risk of tissue damage as well as endoscopic contact.
Pre-curved tip assists cannulation efficiency and reduce operation time.
Colored markers for precise positioning under endoscopic view.
Double-lumen and triple-lumen are both available.

Endoscopic Sphinctetotomy - EST,is developed on the basis of ERCP and endoscopic high frequency electroresection of digestive polyps. Since Classen (Germany) and Kawai (Japan) first carried out in 1974, this method has become a typical representative of minimally invasive treatment of digestive endoscopy.
The most frequent complications of endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic biliary sphincterotomy are pancreatitis(4.3%), cholangitis(0.9%), hemorrhage(0.9%), and duodenal perforation(0.2%).
Endoscopic Sphincterotomy is performed after selective deep ductal cannulation, is regulary performed with the duodenoscope. Normally, to let the cutting wire to be forced toward the roof of the papilla, it is necessary for assistant nurse to bow the sphincterotome. To ensure the cutting wire keep its preferred angle during procedure, sphincterotome with locking mechanism is an ideal function for most nurses.
