目的：到目前为止，还没有一种诊断工具可以客观地评估妊娠期间宫颈的体内生物力学特性。方法：我们首次在临床上应用抽吸装置来评估妊娠期宫颈的生物力学特性，目的是描述妊娠期间的生理生物力学变化，以最终发现有宫颈功能不全(CI)的孕妇。结果：在15次抽吸测量中，12次获得有效结果。刚度值在0.013到0.068巴/毫米之间。结果表明，抽吸试验重复性较好。在我们之前关于非妊娠宫颈的测试系列中，我们的重复测量显示，与
Objective: To date no diagnostic tool is yet available to objectively assess the in vivo biomechanical properties of the uterine cervix during gestation.Methods: We show the first clinical application of an aspiration device to assess the in vivo biomechanical properties of the cervix in pregnancy with the aim to describe the physiological biomechanical changes throughout gestation in order to eventually detect pregnant women at risk for cervical insufficiency (CI).Results: Out of 15 aspiration measurements, 12 produced valid results. The stiffness values were in the range between 0.013 and 0.068 bar/mm. The results showed a good reproducibility of the aspiration test. In our previous test series on non-pregnant cervices our repetitive measurements showed a standard deviation of > 20% compared to
