The purpose of this study was to determine the influence of surgeon's tying technique on knot security using O and 2-O monofilament and multifilament nylon sutures. By use of 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. By use of the portable tensiometer, their knot tying techniques were judged to be superior to those used by a cohort of obstetricians and gynecologists. 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O号和2-O号单丝及多股尼龙缝线，确定外科医生的打结技术对结安全性的影响。通过使用英斯特朗拉伸试验机和便携式张力计，使用四叠方结（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，教导医学生使用双手打结法或器械打结法来打四叠方结。通过使用便携式张力计，判断他们的打结技术优于一组妇产科医生的打结技术。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。
