?:definition
  • Surgical dilators designed for mechanically augmenting the caliber of tracheal strictures/passages by passing them through the mouth and vocal apparatus into the trachea during surgery. These surgical dilators typically consist of an elongated instrument having a distal blunt end and a proximal open end comprising a hollow mouth with sidewalls for receiving and holding the distal end of an endotracheal tube. Endotracheal dilators may have a solid or hollow proximal end that can hold a distal end of a nasal endotracheal tube in place. Endotracheal dilators are used to maintain an open airway, to serve as a conduit through which to administer certain drugs, and sometimes for passing tracheal tubes.
