| 摘要: |
| 目的：设计一种简单便携的脊柱手术实时监测工具并初步评价其应用效果，减少战地脊柱脊髓损伤救治的医源性损伤。方法：自行设计并制备手柄式脊柱内固定导引器。离体脊柱标本随机分为对照组（n=10）和实验组（n=10），对照组采用常规方法进行椎弓根开道，实验组采用自行设计的手柄式脊柱内固定导引器进行椎弓根开道。记录两组各标本的操作时间，术后将标本沿椎弓根平面水平剖开，比较两组标本的开道位置及进针深度。结果：对照组和实验组处理单个椎体时间分别为（0．5±0．2）min、（0．6±0．1）min，两组无统计学差异；对照组穿刺道边缘距离椎弓根壁平均距离（mm）明显短于实验组（1．1±0．3vs1．8±0．2，P=0．037）。结论：手柄式脊柱内固定导引器携带方便，操作简单，体外初步应用效果尚可，能够为早期手术提供可靠参考。 |

| Abstract: |
| Objective: To design a portable real-time monitoring tool for spine surgery and to preliminarily evaluate its application, so as to reduce the iatrogenic injury during the treatment of battle field spinal cord injury. Methods: A portable spine guiding device for spinal fixation was designed and prepared. The spinal specimens were randomly divided into control group (n=10) and experimental group (n=10). In the control group the way was cleared for the pedicle according to the doctor's experience; in the experimental group the way was cleared using our self-designed guiding device. The operation time was recorded in the two groups. After manipulation the specimens were opened along the pedicle level; the location and the depth of the needle were compared. Results: The manipulation time of a single vertebral body was (0.5±0.2) min in the control group and (0.6±0.1) min in the experimental group (P>0.05). The edge of the puncture to the pedicle wall in the control group was significantly shorter than that in the experimental group([1.1±0.3] vs [1.8±0.2]mm,P=0.037).Conclusion:The designed portable guiding device for spinal fixation is easy to carry, simple to operate; and initial in vitro application is satisfactory and can provide reliable reference for early operation. |
