Abstract：Objective To research and develop the effect of a new type of semi-closed fine pleural cavity drainage tube. Methods A closed pleural cavity simulation system was used to simulate puncture leakage. Experimental group was treated with new semi-enclosed fine pleural cavity drainage tube, control group was treated with pig-tail drainage tube with the same diameter. The volume of air leakage during the operation of the pleural cavity enclosed was recorded, 20 times for each group. Bama miniature pigs was used to simulate the operational performance and safety experiments. Twenty puncture sites with good observation were selected under thoracoscopy, and each puncture site was numbered 3 catheterization sites from bottom to top. Pig tail drainage tube of 12F was used in control group (No.1), a new type of semi-closed fine pleural cavity drainage tube with a tip puncture guide needle of type A was used in experimental group (No.2), a new type of semi-closed fine pleural cavity drainage tube with a tip puncture guide needle of type B was used in experimental group (No.3). The operational performance and the rate of lung injury were observed under thoracoscopy, 20 times for each group. Results The average amount of puncture leakage in the experimental group was significantly lower than that in the control group, and the difference was statistically significant (P < 0.05). All the groups were able to successfully placed into the pleural cavity of bama miniature pig, and the rupture in parietal pleura of experimental group (No.2) and experimental group (No.3) was the same as that of the control group (No.1). When needling at the depth of 10 mm, the rate of injury in the experimental group was lower than that in the control group, the difference was not statistically significant (P > 0.05). When needling at the depth of 20 mm, the rate of injury in the experimental group was lower that in the control group, the difference was statistically significant (P < 0.05). Conclusion The new semi-enclosed fine pleural cavity drainage tube has the advantages of simple structure and accurate prompt, and can effectively reduce the risk of iatrogenic pneumothorax and visceral injury. At the same time, one-step catheterization is simple, safe and has good clinical value.
