BACKGROUND@#With the extensive development of minimally invasive surgery for pulmonary nodules, preoperative localization becomes more and more critical. There are some defects in traditional localization methods, so it is necessary to improve. The aim of this study was to compare and analyze the safety and effectiveness of two new methods, namely four-hook needle and memory alloy coil, in the localization of pulmonary nodules.@*METHODS@#A retrospective analysis of 152 patients was performed. 76 cases were in four-hook needle group, and 76 cases were in memory alloy coil group. Pulmonary nodules were located before operation, and then video-assisted wedge resection was performed. The average procedure time, localization complications and nodule resection time were counted.@*RESULTS@#The target pulmonary nodules were successfully removed in both groups. In four-hook needle group, 76 patients found localization devices, all the pulmonary nodules were successfully removed, and one case was transferred to open the chest for wedge resection of pulmonary nodules due to severe thoracic adhesion. All 76 patients in memory alloy coil group were successfully resected with pulmonary nodules, and one patient underwent compromising enlarged resection because no lesion was found after the specimen was removed during the operation. There was no significant difference in the incidence of pneumothorax and pulmonary hemorrhage, the success rate of localization and nodule wedge resection time between the two groups. The average time of localization in four-hook needle group was (13.66±3.11) min, lower than that of memory alloy coil group (15.51±3.65) min, and the difference was statistically significant (P=0.001). In memory alloy coil group, when the distance from the nodule to the pleura was ≥1.5 cm and <1.5 cm, the average localization time was (17.20±4.46) min and (14.91±3.15) min, respectively, and there was a statistical difference between the two distance (P=0.044).@*CONCLUSIONS@#Four-hook needle and memory alloy coil have good safety and effectiveness, and the localization time of four-hook needle is shorter. When using memory alloy coil, the effect of the method is better for pulmonary nodules with a distance less than 1.5 cm to pleura.

The rapid development of minimally invasive surgery in thoracic surgery has significant advantages over traditional surgery.At the same time, problems such as the difficulty in obtaining specimens from small incisions and the increase in operating costs due to special medical consumables have also emerged. Therefore, how to remove surgical specimens safely, efficiently and cost-effectively is an important issue faced by thoracic surgeons during surgery. Operating room sterile gloves are often used as specimen collection bags and widely used in thoracic surgery and many other departments because of their easy availability, low cost, and good flexibility. At present, most of the glove specimen collection bags are based on sterile gloves, and various manufacturing methods have evolved by the combination with instruments and sutures.This article will briefly review the application of various forms of glove specimen retrieval bags in thoracoscopic surgery reported in existing research, analyze their advantages, disadvantages and scope of application, so as to provide references for future clinical applications and technological innovation researches.
