根据病变大小、病变外缘与胸壁内缘距离、病变肺叶等条件应用配对设计分组法，将64例直径≤3.0 cm、病变与相邻胸膜不接触的孤立肺结节患者分为行自制导引器引导针定位法穿刺活检（引导组）和常规法穿刺活检（常规组），每组各32例。引导组和常规组首次穿刺成功率分别为97％(31/32)和72％ (23/32)，穿刺成功所用时间分别为(13.5±4.9)和(18.7±5.7)min，并发症发生率分别为9％ (3/32)和28％ (9/32)，两组间差异均有统计学意义(P＜0.05)。采用该导引器引导针定位法可明显提高肺内小病灶的首次穿刺成功率，减少操作时间和并发症发生率。

Sixty-four patients with solitary pulmonary nodules were included in this study. The diameter of pulmonary nodules was equal or less than 3.0 cm and no contact with the adjacent pleura. They were divided into study group( with acuductor locating method)and conventional group (with conventional method). The results showed that the one-time success rates were 97％ (31/32)in study group and 72％(23/32) in conventional group, the diagnostic accuracy were 94％ ( 30/32 ) and 88 ％ ( 28/32 ), respectively,while the successful puncture time were( 13. 5 ±4. 9)min and( 18. 7 ±5. 7) min, respectively. In study group,the complication rate was 9％ (3/32), while 28％ ( 9/32 ) in conventional group. There were statistical differences between the two groups. CT-guided aspriation biopsy for solitary pulmonary nodules with self-made acuductor can obviously improve one-time success rate and reduce the complication rate and operative time.
