新型定位穿刺方法在椎间孔镜手术初学者中的应用

Application of a new positioning and puncture methods in beginner of percutaneous endoscopic lumbar discectomy

目的探讨个体化术前设计结合定位穿刺导向器在椎间孔镜手术初学者中的应用价值。方法选取2019年10月-2020年4月在娄底市中心医院行侧后方入路椎间孔镜手术的椎间盘突出患者32例,由同一名初学者按照常规组与实验组对应方法完成定位穿刺步骤,比较两组透视次数、穿刺成功所需的穿刺针调整次数。结果常规组与实验组透视次数的中位数及极值分别为23.50 (14~32)次和10.00 (8~14)次,穿刺针调整次数分别为5.50 (2~13)次和1.00 (0~2)次,两组比较,差异均有统计学意义(P <0.05)。结论椎间孔镜手术初学者应用个体化术前设计结合定位穿刺导向器可减少透视次数,提高穿刺准确性。

Objective To explore the application value of individualized preoperative design combined with localization puncture guide in beginner of percutaneous endoscopic lumbar discectomy.Methods 32 patients with disc herniation who underwent percutaneous endoscopic lumbar discectomy of posterior lateral appropach from October 2019 to April 2020.The same beginner completes the positioning puncture step according to the corresponding method of the regular group and the experimental group.Compare the fluoroscopy times and the puncture needle adjustment times required for successful puncture between the two groups.Results The median and extreme values of the fluoroscopy frequency of the routine group and the experimental group were 23.50(14~32)times,10.00(8~14)times,and the puncture needle adjustment times were 5.50(2~13)times,1.00(0~2)times(P<0.05).Conclusion For beginners of percutaneous endoscopic lumbar discectomy,the application of individual preoperative design combined with positioning puncture guide can reduce the number of fluoroscopy and improve the accuracy of puncture.
