目的：探讨CT三维立体全身穿刺定位装置的研发以及用于经皮肺穿刺的临床意义。方法：构思CT三维立体全身穿刺定位装置，将88例经皮肺穿刺患者随机分为观察组和对照组，每组44例。观察组应用研制的CT三维立体全身穿刺定位装置引导穿刺，对照组采用传统的CT引导徒手穿刺，两组由同一位经验丰富的医师操作。穿刺后留针CT扫描，观察穿刺一次命中率、穿刺时间、确诊后的阳性率对照、气胸和肺组织出血情况以及CT重复扫描次数情况，并进行对比分析。结果：观察组穿刺一次成功率为100%，平均穿刺时间为5.5 min，确诊后的阳性率为97.7%，气胸发生率为15.9%，肺组织出血发生率为36.4%，平均CT扫描3.0次。对照组穿刺一次成功率为52.3%，平均穿刺时间为11.3 min，确诊后阳性率为68.2%，气胸发生率为35%，出血发生率为52%，平均CT扫描5.0次。结论：CT三维立体全身穿刺定位装置设计新颖，操作简单，精确度高，应用于临床可提高穿刺成功率，缩短穿刺时间，减少CT扫描次数和并发症的发生，值得推广。

Objective:To investigate the development of needle positioning device of three-dimensional body was guided in the CT and applied in lung puncture of the clinical research. Methods: To develop a device of three-dimensional concept of body which used puncture location under the precise guided by CT. 88 cases of lung biopsy patients were divided into two groups randomly: observation group and control group were 44 cases. Observation group used CT which used three-dimensional body device to puncture location, Control group used conventional CT-guided puncture. Two groups were operated by the same experienced physician. Observe puncture hits, puncture time, the contract of positive rate which had diagnosed, pneumothorax, pulmonary tissue hemorrhage by CT scan, analyzed different CT scan results.Results: One success rate reached 100 percent in observation group, the average puncture time were(excluding preoperative preparation, counting the puncture time after completed disinfection) 5.5 minutes, of which were diagnosed the positive rate reached 97.7%, pneumothorax was 15.9%, lung tissue bleeding rate 36.4% ,the average CT scan were 3 times; one success rate of control group was 52.3%, the average puncture time were 11.3 minutes, of which were diagnosed the positive rate reached 68.2%, pneumothorax was35%, bleeding rate was52%, the average CT scan were 5 times.Conclusion: CT-guided needle positioning device of three-dimensional body is novel design, simply operation and high accuracy. It is worth promoting to clinic by improve the success rate, shorten the puncture time, reduce the number of CT scans and complications.
