Abstract
A single stage instrument is used to insert a chest drainage tube into the inter-pleural space to facilitate drainage. The instrument is scissor-like with cylinder-like channels to slidably enclose the distal section of the tube therein when closed. The tip of the instrument is curved to enter the skin incision and the offset pleural incision whereafter the instrument is rotated 180 degrees to align the curved tip with the pleural space. The curved tip facilitates sliding the chest drainage tube through the instrument to effect sufficient insertion length. Once the instrument is in place, the tube is slid along the instrument to ensure that all drainage holes in the chest drainage tube are within the pleural cavity. Thereafter, the instrument is withdrawn leaving the chest drainage tube in place. After withdrawal of the instrument, it is opened laterally for lateral disengagement with the chest drainage tube.
