Application of pelvic-style docking in robotic surgery for lower-middle mediastinal tumors.

For robotic surgery, in a field of view looking upwards, the target lesion to be operated on should lie between the camera port and the robot. The ports are placed at the bottom of the chest wall. If the tumor is located below the inferior pulmonary vein, it is necessary to devise alternative port placement and robot docking methods. In 4 patients who had lower middle mediastinal tumors, the "Pelvic" setting on the visual pad of the patient cart was used, which allows easy access for lower middle mediastinal manipulation and results in minimal issues with robotic arm collisions.
