Simulation of VATS for Lobectomy Using a Lifelike Chest Model

A life-sized chest model with a lifelike texture was developed to simulate thoracoscopic surgery. Video-assisted thoracoscopic surgery (VATS) for right lower lobectomy was performed using the model.<div>This novel model was developed using a computed tomography (CT) data obtained from a healthy Japanese man. A mold of the chest organs was created by three-dimensional printing, and then used to cast the model using industrial methods. The major blood vessels and bronchi within the lungs are anatomically correct and continuous with the mediastinum, which was cast as a plate. The lung parenchyma was cast from polyvinyl alcohol foam and incudes water and air, which gives it a soft, elastic texture and renders it electrically conductive. The sensations of cutting, suturing, and surgical stapling are similar to live surgery. It is also possible to use powered instruments.<br></div><div>Disclosure<br>This model was co-developed with FASOTEC Co. Ltd., Chiba, Japan.<br></div>
