The purpose of this study was to determine the influence of the surgeon's tying technique on knot security using 0 and 2-0 monofilament and multifilament nylon sutures. Using an Instron Tensile Tester and a portable tensiometer, knot security was achieved with these sutures using four-throw square knots (1 = 1 = 1 = 1). After didactic and psychomotor skill training, medical students were taught to construct the four-throw square knot using either a two-hand tie or an instrument tie. Using the portable tensiometer, their knot tying techniques were judged to be superior to those used by surgeons. The surgeon's faulty technique can easily be corrected by didactic information and psychomotor skill training.
本研究的目的是使用0号和2-0号单丝及多丝尼龙缝线，确定外科医生的打结技术对结安全性的影响。使用英斯特朗拉伸试验机和便携式张力计，通过四叠方结（1 = 1 = 1 = 1）实现了这些缝线的结安全性。在进行理论和操作技能培训后，医学生学习了使用双手打结或器械打结的方法来构建四叠方结。使用便携式张力计判断，他们的打结技术优于外科医生。通过理论知识和操作技能培训，可以轻松纠正外科医生的错误技术。
