Establishment of acquired tracheoesophageal fistula using a modified magnetic compression technique in rabbits and its postmodeling evaluation

Figure 1 Schematic of the modified magnetic compression technique. A: Inserting 3.5 mm and 5.5 mm tracheal intubation into the trachea and esophagus respectively; B: Placing the daughter magnet (DM) and parent magnet (PM) inside the tracheal intubation and pushing them to the intubation's end using a guide wire; C: Gently pushing the PM towards the end using the guide wire; D: Under the influence of magnetic force, the DM and PM attract each other, detach from tracheal intubation, and adhere to the tracheal and esophageal mucosa; E: Removing the tracheal intubation and guide wire; F: Separation of the magnets, entry into the esophagus, and expulsion from the body through the digestive tract. Tr: Trachea; TI: Tracheal intubation; E: Esophagus; DM: Daughter magnet; PM: Parent magnet.
