Oesophageal Probang This is an Oesophageal Probang. It features a long, spiral metal stem that ends on one side with a blunt metal tip, encapsulating white horsehair. The other end has a finger ring, which is detachable thanks to a screw-in bolt. The instrument shows signs of wear and tear. By pulling the finger ring, the internal metal rod pulls the horsehair and can rotate it, creating a web-like structure to trap and remove foreign objects from the throat. 1875-1925
