The Efficacy of Intraoperative Pulmonary Nodules Localization Guided by Virtual Reality Technology

Study on the Localizing of Intraoperative Pulmonary Nodules Guided by Virtual Reality Technology

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

Study Overview

• Status: Withdrawn
• Conditions: Lung Neoplasm
• Intervention / Treatment: Device: LungBrella marker implantation and VATS partial lobe resection

Detailed Description

This is a prospective, mulitiple-center clinical trial initiated by the investigator. LungBrella marker can be accurately 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. The study is expected to enroll 90 patients. Finally, the effectiveness and safety of the method will be evaluated. This method not only can complete pulmonary nodule localization in the operating room without occupying the resources of radiology department, but also can let patients receive pulmonary nodule location after anesthesia. Thereby the risks during transportation are avoided and the suffering of patients is reduced.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Arm 1; 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; 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 .

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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 Outcome Measures
