文题释义
经皮椎间孔镜技术:是目前治疗腰椎间盘突出症创伤最小的方法之一,对脊柱的稳定性破坏最小,在局麻下进行。使用一种逐级钻孔器扩大椎间孔,将上关节突外侧缘部分骨质绞除扩大椎间孔从而建立手术通道,使术者能够直接通过椎间孔到达椎管内从而取出突出的椎间盘组织。由于这种手术是在内镜下的直视操作,避免了各种经皮穿刺技术的盲目性,所以操作十分安全,而且疗效可靠。
自制经皮椎间孔镜穿刺导向器:椎间孔镜定位导向器的研制是依据直角三角形几何学原理,直角三角形的2条直角边长度可决定斜边的长度及角度大小。定位导向器由滑动架、滑动螺栓、旋钮、锁定螺栓及导向套5部分组成。滑动架是具有线性延伸的导向架身,标尺上有清晰的长度。穿刺导向套管通过滑动轨道及锁止部连接并固定于滑动架,并可在标尺上移动。穿刺导向套管可借助锁止部改变穿刺方向。
 
摘要
背景:经皮椎间孔镜手术是目前治疗腰椎间盘突出症最微创的术式,确保穿刺针能准确到达目标靶点是手术成功的关键。但经皮椎间孔镜技术有陡峭的学习曲线,初学者徒手穿刺容易导致穿刺不到位。
目的:评价自行设计椎间孔镜穿刺导向器的穿刺导向准确性和安全性。
方法:利用“直角三角形”原理设计出经皮椎间孔镜穿刺导向器。选择2014年1月至2016年7月在济宁医学院附属滕州市中心人民医院脊柱外科接受经皮椎间孔镜手术的单节段腰椎间盘突出症患者60例,随机分为2组,其中导向器组33例手术中辅助经皮椎间孔镜穿刺导向器完成手术,徒手组27例则采用徒手穿刺完成手术。比较2组患者穿刺次数、穿刺时间、透视次数及术后1年日本骨科协会评分、Oswestry功能障碍指数。
结果与结论:①2组患者均顺利完成手术;②导向器组的穿刺次数、穿刺完成前透视次数、定位穿刺时间均小于徒手组,差异均有显著性意义(P < 0.05);③2组患者术后1年随访,日本骨科协会评分及Oswestry功能障碍指数均较术前显著改善(P < 0.05);2组之间日本骨科协会评分及Oswestry功能障碍指数相比,差异无显著性意义(P > 0.05);④提示根据“直角三角形”原理设计出的穿刺导向器可提高经皮椎间孔镜穿刺操作的准确性,尤其适用于初学者。

Abstract:

BACKGROUND: Percutaneous transforaminal endoscopic discectomy is currently the most minimally invasive treatment of lumbar disc herniation. It is essential to operation success that the puncture needle can accurately reach the target. But percutaneous transforaminal endoscopic discectomy has steep learning curve. Free hand can easily result in inadequate puncture.

OBJECTIVE: To evaluate the puncture accuracy and safety of percutaneous puncture guidance instrument for percutaneous transforaminal endoscopic discectomy.
METHODS: The design principle of puncture guidance instrument for percutaneous transforaminal endoscopic discectomy was right triangle. From January 2014 to July 2016, 60 patients with lumber disc herniation were randomly divided into navigation group (n=33, percutaneous transforaminal endoscopic discectomy with a novel puncture guidance instrument) and free hand group (n=27, percutaneous transforaminal endoscopic discectomy with a free hand method).The times for puncture, puncture time, times for fluoroscopy, Japanese Orthopaedic Association score and Oswestry Disability Index at 1 year postoperatively were recorded and compared between two groups.
RESULTS AND CONCLUSION: (1) All patients underwent the operation successfully. (2) The average puncture times, the average fluoroscopic exposure time and the preoperative location and puncture-channel time in the navigation group were significantly less than those in the free hand group (P < 0.05). (3) Japanese Orthopaedic Association scores and Oswestry Disability Index at 1 year postoperatively in both groups were significantly improved compared with the baseline (P < 0.05). The scores showed no significant differences between two groups (P > 0.05). (4) Our results indicate that the puncture guidance instrument for percutaneous transforaminal endoscopic discectomy can improve the puncture accuracy, especially for a beginner.
