【摘要】：背景:目前足部有限元模型的材料特性和参数大多参考国外文献,尚未见国内开展材料参数的测试研究工作的报道。国内常用的方法用游标卡尺测量韧带、肌腱的宽度和厚度计算截面积。目的:设计一种测量韧带横截面积的新仪器,提高测量精度。方法:通过设计一种新型韧带横截面积测量仪器,分别应用该新型仪器与传统游标卡尺对5具新鲜尸体踝关节韧带横截面积进行测量,然后对两种测量方法进行对比分析。结果与结论:1游标卡尺测量组距腓前韧带、跟腓韧带、胫舟韧带、胫跟韧带的横截面积平均值分别为(20.61±7.52)、(22.38±11.49)、(33.09±9.91)、(28.20±10.88)mm2,新型韧带横截面积测量仪器为(17.59±4.03)、(20.77±7.91)、(28.08±8.14)、(30.39±7.98)mm2,两种方法测量结果差异均无显著性意义,结果相当。2结果说明,该新型韧带横截面积测量仪操作简便,测量结果较准确可靠,填补了韧带横截面积测量实验无专用仪器的空白,其应用价值值得进一步研究。
[Abstract]:Background: at present, most of the material characteristics and parameters of the foot finite element model refer to the foreign literature, but there is no domestic report on the testing and research of the material parameters. The common methods used in China are measuring ligaments with Vernier calipers. The width and thickness of tendon were calculated. Objective: to design a new instrument to measure the cross-sectional area of ligaments in order to improve the measuring accuracy. Methods: a new instrument was designed to measure the cross-sectional area of ligaments. The new instrument and traditional Vernier caliper were used to measure the cross-sectional area of ankle ligament in 5 fresh cadavers. The results and conclusions: 1 Vernier caliper measured the anterior talofibular ligament, calcaneal ligament and tibial scaphoid ligament. The average cross-sectional area of tibial ligament was 20.61 卤7.52 and 22.38 卤11.49, respectively (33.09 卤9.91). The new apparatus for measuring the cross-sectional area of ligamentum was 17.59 卤4.03mm2, 20.77 卤7.91mm2, 28.08 卤8.14). There was no significant difference between the two methods (30.39 卤7.98 mm ~ 2), and the results were equivalent to .2. The results showed that the new type of ligament cross-sectional area measuring instrument was easy to operate. The measurement results are accurate and reliable, which fill the blank in the experiment of ligament cross-sectional area measurement without special instrument, and its application value is worthy of further study.
