The 4 steps of chest tube insertion into a cadaver using the new trocar.

A, The creation of an incision in the skin with a surgical scalpel. B, The puncturing of the thoracic wall with the trocar, which is then pushed into the thoracic cavity. C, The drawing of the stylet out of the mold and the insertion of the chest tube through the mold. D, The removal of the mold from the thoracic wall.

In general, a chest tube is inserted for drainage to treat conditions such as pneumothorax, hemothorax, and pyothorax. Because of the clinical usefulness of closed thoracostomies, the ability to perform this procedure is an essential skill for not only physicians who treat trauma patients but also general surgeons and emergency physicians [1–2]. In this method, there is a lengthy period between incision and chest tube insertion (CTI); as a result, air within the thoracic cavity can leak out to reexpand the lung, which may increase the possibility of lung injury caused by the chest tube.
