研究目的:

1.主要目的:探索穿刺定位导航机器人在术前辅助定位肺结节位置的安全性和有效性。 2.次要目的:通过穿刺定位导航机器人辅助定位方法,探索胸腔镜肺楔形切除术可否获得安全边界。  

Objectives of Study:

1. Main objective: To explore the safety and effectiveness of the puncture positioning navigation robot in preoperative localization of pulmonary nodules. 2.Secondary objective: To explore whether a safe margin can be achieved in thoracoscopic wedge resection of the lung through the puncture positioning navigation robot-assisted localization method.

药物成份或治疗方案详述:

根据患者CT图像中肺磨玻璃结节的位置,术者选择便于穿刺的体位,体位固定后,患者首先接受第一次CT扫描以成像肺部图像,然后将CT图像传输到RC 120导航系统。操作者在RC 120导航系统的操作界面上规划垂直于胸膜的最短穿刺路径,确定穿刺针的进针位置、方向和深度,RC 120导航系统自动完成机械臂的运动轨迹规划,然后机械臂变换姿态移动到目标穿刺点的上方位置。局部浸润麻醉,然后使用穿刺针沿着预定的穿刺路径手动完成最后的穿刺定位。随后,通过第二次CT扫描来验证穿刺针头端的位置是否达到预期目标位置,CT扫描确定位置无误后,取下穿刺针的保险扣,按压推杆释放四钩定位针,拔出穿刺针并包扎穿刺点,立即重复 CT扫描确认定位针的位置及有无气胸等并发症。 在穿刺定位术后24小时内均接受喉罩全麻下单孔VTAS肺楔形切除术,术中肉眼观察定位针是否脱钩,并通过脏层胸膜表面三色定位线的颜色和长度来评估目标肺结节的深度,然后采用卵圆钳头端测量切缘距离,电凝勾灼烧标记切缘后,利用直线切割闭合钉(Endo-GIA)楔形切除肺结节。立即切开标本,记录定位针与结节外缘的距离以及切缘距离,随后立即送检快速冰冻检查。 

Description for medicine or protocol of treatment in detail:

Based on the location of the GGN in the patient's CT images, the surgeon chose a suitable position for puncture. After positioning, the patient underwent the first CT scan to image the lungs, and the CT images were then transmitted to the RC120 navigation system. The operator planned the shortest puncture path perpendicular to the pleura on the RC120 navigation system interface and determined the puncture point, direction, and depth. After sending the confirmation command, the RC120 navigation system automatically completed the motion trajectory planning for the robotic arm. The operator then used 2% lidocaine for local subcutaneous infiltration anesthesia and performed the final puncture manually using a 4-hook soft-wire puncture needle along the planned puncture path. Subsequently, a second CT scan was performed to verify whether the tip of the puncture needle reached the intended target position. After confirming the correct position with CT scanning, the safety latch of the puncture needle was removed, the push rod was pressed to release the 4-hook localization needle, the puncture needle was withdrawn, and the puncture site was bandaged. A repeat CT scan was immediately performed to confirm the position of the localization needle and check for complications such as pneumothorax. Within 24 hours after the localization procedure, all patients underwent single-port VATS wedge resection under laryngeal mask anesthesia. Intraoperatively, the surgeon visually assessed whether the localization needle had dislodged and evaluated the depth of the target nodule based on the color and length of the tricolored suture outside the pleura. The margin distance was measured using the tip of a sponge forceps, and the resection margin was marked with an electric coagulation hook before wedge resection using a linear stapler (Endo-GIA). The specimen was immediately incised, and the distance between the claw and the nodule edge, as well as the margin distance, were recorded. The specimen was then sent for rapid frozen pathological examination.
