Summary

This study aims to conduct a large-sample randomized controlled clinical trial, using traditional CT-guided thoracic puncture localization as a comparison, to explore the accuracy, safety and clinical advantages of Intelligent AR glasses in assisting preoperative localizing of small pulmonary nodules.

Conditions

  • Pulmonary Nodule

Interventions

PROCEDURE

AR glasses-assisted pulmonary nodule puncture localization

Combined with placing positioning marks on the patient's body surface and tracing the needle entry point with the assistance of a CT scan gantry laser. Disinfect the area around the puncture needle point, and use 2% lidocaine for local infiltration anesthesia. The doctor wears augmented reality (AR) glasses, completes the connection between the AR glasses and the puncture target, and clicks on the puncture point plane through the puncture target needle tip. Calibrate the puncture position at any two points. After confirming that the patient has held his breath, quickly puncture the needle into the pleura and advance it to the planned puncture position according to the screen prompts. After the second CT scan is performed to confirm that the puncture needle is positioned at a reasonable position, the positioning hook wire is released and the puncture needle sheath is withdrawn.

PROCEDURE

CT-guided pulmonary nodule puncture localization

Positioning markers are placed on the patient's surface and the first CT scan is performed. The needle insertion point and needle insertion depth are designed based on the two-dimensional CT scan image and the positioning marks. The location of the needle entry point was traced with the laser assistance of the CT gantry. Disinfect and puncture around the needle point, and use 2% lidocaine for local infiltration anesthesia. According to the designed needle path angle, the needle is first inserted under the skin, and a second CT scan is performed to confirm that the extension line of the puncture needle is within the nodule range. Then the needle is inserted to the target depth, and the third CT scan is performed. After confirming that the puncture needle is positioned at a reasonable position, the positioning hook wire is released and the puncture needle sheath is withdrawn.
