Abstract

See full text

This invention relates to a small bell-shaped latex rubber protector that is designed to be placed over the top of, e.g., an endoscope prior to its passage into a body cavity through a tract thereof. Once it is passed in a folded back position, a sharp, pointed or cutting foreign object can be retrieved from the cavity using a forceps or other accessory. The protector hood is then flipped into the open position by pulling the instrument back through, e.g., the lower esophageal narrowing. The bell-shaped latex protects, for example, the esophagus and posterior pharynx from the foreign body during its removal.
