The security of six different laparoscopic clips was investigated using 60 kryopreserved specimens of human cystic ducts. After fixation of the cystic duct the cross placed clips were distracted in axial direction and the maximum forces to remove the clip were registered. The mean dislocation-force was 4.6 Newton for titanium clips and 9.3 Newton for absorbable clips with a highly significant difference (p < 0.001, Wilcoxon-test). Additional to the advantage of complete biodegradibility these data favour the use of absorbable clips, because of a better hold force compared to titannium clips.
使用60个冷冻保存的人胆囊管标本，对六种不同的腹腔镜夹的安全性进行了研究。在固定胆囊管后，将交叉放置的夹子沿轴向拉开，并记录移除夹子所需的最大力。钛夹的平均脱位力为4.6牛顿，可吸收夹为9.3牛顿，差异极显著（p < 0.001，Wilcoxon检验）。除了完全可生物降解的优点外，由于与钛夹相比具有更好的夹持力，这些数据支持使用可吸收夹。
