Abstract

Objective To evaluate the efficacy and safety of a novel CT-guided memory alloy puncture localization needle (with a spring-coil tip at the front end) in thoracoscopic resection of pulmonary nodules. Methods A retrospective analysis was conducted on 40 patients who underwent thoracoscopic pulmonary nodule resection between June 2023 and January 2025. Ten patients received CT-guided localization using a new needle before the operation (localization-assisted group), while 30 patients underwent conventional thoracoscopic surgery (conventional surgery group). Localization success rate, operative time, intraoperative blood loss, hospital stay, and complication rates were recorded and compared between the two groups. Results The localization technique and nodule resection success rates of the 10 patients were both 100% in the localization-assisted group (10 patients). Compared with the conventional surgery group, the localization-assisted group demonstrated significantly shorter operative time and significantly reduced intraoperative blood loss (all P<0.05). The complication rate was lower in the localization-assisted group (1 case of mild pneumothorax/subcutaneous emphysema; 1 case of transient intraoperative pain). There was no statistically significant difference in hospital stay between the two groups (P=0.201). Conclusions The novel CT-guided memory alloy puncture localization needle is safe and effective for thoracoscopic pulmonary nodule resection. It is precise and reliable in localization, can significantly shorten the operative time, reduce intraoperative bleeding, and has fewer complications.
