Abstract

Background: Surgeons face numerous choices in selecting sutures for skin closure, with potential adverse effects such as tissue tearing.

Objective: To investigate the influence of needle design and suture gauge on tissue tearing during suturing procedures.

Materials and methods: The authors tested the tear-through force in Newtons for 3 needle types and 3 suture gauges using an artificial skin model and a professional-grade tensiometer. Suture material was secured into the skin model, and force was applied to the suture at a constant rate, resulting in tearing. Force-displacement and force-time curves were generated. Evaluation included conventional cutting (PC-3), reverse cutting (PS-3), and taper point (BB) needles with a 5-0 polypropylene suture. In addition, nylon sutures with a reverse cutting needle (PS-2) were tested at 3 suture gauges (5-0, 4-0, 3-0).

Results: The mean tear-through forces for PC-3, PS-3, and BB were 3.26 N, 3.75 N, and 4.07 N, respectively. For the 5-0, 4-0, and 3-0 nylon sutures, the mean tear-through forces were 3.44 N, 3.81 N, and 4.04 N, respectively. Statistical analysis revealed a significant impact of suture gauge size ( p < .001) and needle geometry ( p < .001) on tear-through force.

Conclusion: Larger suture diameter and taper needles minimize tissue tearing.

缝针设计和缝线规格对皮肤缝合时组织撕裂的影响：对比分析

背景：外科医生在选择缝合线进行皮肤缝合时面临多种选择，可能会造成组织撕裂等不良影响：研究缝合针设计和缝合线规格对缝合过程中组织撕裂的影响：作者使用人工皮肤模型和专业级张力计测试了 3 种针型和 3 种缝线规格的撕裂力（以牛顿为单位）。将缝合材料固定在皮肤模型上，以恒定的速度向缝合线施加力，导致撕裂。生成力-位移和力-时间曲线。评估包括使用 5-0 聚丙烯缝合线的传统切割针 (PC-3)、反向切割针 (PS-3) 和锥尖针 (BB)。此外，还对使用反向切割针（PS-2）的尼龙缝合线进行了 3 种缝合线号（5-0、4-0、3-0）的测试：结果：PC-3、PS-3 和 BB 的平均撕裂力分别为 3.26 N、3.75 N 和 4.07 N。5-0、4-0 和 3-0 尼龙缝合线的平均撕脱力分别为 3.44 N、3.81 N 和 4.04 N。统计分析显示，缝合线规尺寸（p < .001）和缝针几何形状（p < .001）对撕脱力有显著影响：结论：较大的缝合线直径和锥形针能最大程度地减少组织撕裂。
