摘要：
A tracheal tube assembly includes an outer cannula configured to be positioned in a tracheal passageway and a first inner cannula configured to be disposed inside the outer cannula. The tracheal tube assembly further includes a flange member secured about the outer cannula, and a connector coupled to a proximal end of the outer cannula or of the first inner cannula. The outer cannula includes a length suitable for only minimally protruding outside of the tracheal passageway, if at all, to improve phonation.
