Definition : Trocars designed for percutaneous puncture of the tracheal tube through the skin and cricothyroid membrane. These instruments typically consist of a manual, handheld device with a sharp pyramidal strong, short, and curved pointed rod at the distal end and a proximal large handle. Tracheal trocars are usually fitted into a metal cannula and are used to pierce the skin and the cricothyroid membrane reaching the trachea and are then removed, leaving the cannula in place (i.e., to perform a tracheotomy or cricothyrotomy). Tracheal trocars (e.g., Ueckermann trocars) are intended to provide access to the trachea in emergency situations, providing an opening for the insertion of a tracheotomy tube.
