There is a lack of information regarding the forces required for suturing human wounds. The knowledge of suturing forces serves as complementary information for setting up the limiting geometry when using tissue adhesives and it might also be used in robot-assisted surgery. The main purpose of this paper was to evaluate the forces required for suturing selected skin wounds. An elliptical wound was chosen for our study. In this study a numerical analysis and in vivo experiments were performed. Regarding the numerical models, the maximum forces occurred in the middle of the elliptical wound in all cases. In the case of highest pre-stress used in these analyses the maximal force varied from 0.5 N for the smallest wound (30 × 5 mm) to 1.5 N for the largest wound (30 × 15 mm). The maximum peak force for the wound with a size of 46 × 13 mm was 3.2 N. The minimum peak force for the wound with a size of 36 × 5 mm was 1.1 N.
关于缝合人体伤口所需的力的信息还很缺乏。缝合力的知识是使用组织粘合剂时设置限制几何形状的补充信息，它也可能用于机器人辅助手术。本文的主要目的是评估缝合选定皮肤伤口所需的力。我们选择了椭圆形伤口进行研究。在这项研究中，进行了数值分析和体内实验。关于数值模型，在所有情况下，椭圆形伤口的中间处出现了最大的力。在这些分析中使用的最高预应力度下，最大力从最小伤口（30×5mm）的 0.5N 变化到最大伤口（30×15mm）的 1.5N。尺寸为 46×13mm 的伤口的最大峰值力为 3.2N。尺寸为 36×5mm 的伤口的最小峰值力为 1.1N。
