Brief Summary

As the detection of small pulmonary nodules continuously grows, the intraoperative localization of small pulmonary nodules is in great demand. The intraoperative localization nowadays is usually done under local anesthesia before surgery. There is a certain rate of failure and complication. The result of our early animal experiments show that the pulmonary surgery marker system can deliver the intraoperative localization safely and precisely under anesthesia, and the average distance between the localization and the simulated lesion is less than 5mm during surgery. Therefore, the safety and feasibility of the system require further evaluation in patients

Conditions

Lung Neoplasm

Keywords

Lung Neoplasm; localization of lung nodules; ground glass opacity; sublobar resection

Outcome Measures

Primary Outcomes (1)

• Positioning success rate

  When the distance between the LungBrella marker and the Pulmonary nodule is less than 10mm, the marker position is successful. The success rate is the proportion of successful cases to all operation cases

  Immediately after resection

Secondary Outcomes (1)

• Procedure time

  Duration of procedure

Study Arms (1)

Arm 1

EXPERIMENTAL

LungBrella marker implanted into a predetermined position in the lung assisted by JediVision software and successfully marked the pulmonary nodules which needs to undergo Video-assisted thoracoscopic surgery

Device: LungBrella marker implantation and VATS partial lobe resection

Interventions

LungBrella marker implantation and VATS partial lobe resection DEVICE

The enrolled patients will receive a plain chest CT scan,then the data be loaded into JediVision software. The JediVision software can navigate the location of nodule and facilitate the implantation of LungBrella marker in the operating room after general anesthesia,then the patients will receive VATS partial lobe resection .
