Details of the “margin localizer” clamps. Two size clamps have been designed for nodules up to 1 and 1.5 cm, respectively. The inner diameters are measured based on the most recent literature-based recommendations on tumor-free margins for primary and secondary lung cancers. (Color version of figure is available online.)

Schematics of the “tattooing” technique (from upper left to bottom right). After removing the clamp, the remaining tattoo around the nodule guides the resection at a safe distance from the tumor.
