Kryopreserved specimens of cystic ducts were used for displacement tests to investigate the security of different laparoscopic clips. The cystic duct was fixed, and the transverse placed clips were distracted in axial direction and the forces registered. The median values of the six investigated clips ranged between 4.1 N and 11.2 N with a highly significant difference (P < 0.001, Kruskal-Wallis ANOVA). In detail, both resorbable clips (polydioxanone, polyglyconate/polyglycol acetate) were superior to the four titanium clips (P < 0.005, Wilcoxon test). In addition to the advantage of complete biodegradibility, these data favour the use of absorbable clips because holding force is better than that of titanium clips.
采用经低温保存的胆囊管标本进行移位试验，以研究不同腹腔镜夹的安全性。将胆囊管固定，对横向放置的夹子沿轴向进行牵拉并记录所施加的力。所研究的六种夹子的中位数力值在4.1 N至11.2 N之间，差异具有高度显著性（P < 0.001，Kruskal-Wallis方差分析）。具体而言，两种可吸收夹（聚二氧六环酮、聚甘醇酸/聚乙醇酸醋酸酯）均优于四种钛夹（P < 0.005，Wilcoxon检验）。除了完全可生物降解的优点外，这些数据支持使用可吸收夹，因为其夹持力优于钛夹。
