The Bakes Gall Duct Dilator (also commonly referred to as a Bakes Common Bile Duct Dilator) is a specialized general surgery and gastroenterology instrument designed to safely widen narrowed bile ducts and probe for retained gallstones. It features an ovoid, bulb-shaped or "rosebud" tip attached to a thin, malleable shaft. This flexibility allows surgeons to gently bend and guide the instrument through the natural curves of the biliary tree without causing accidental perforations or tissue lacerations.
