临床上应用的缝线,无论在缝合伤口时或在手术后阶段很少仍保持干燥,缝线和身体脂肪、体液接触,改变了表面特性并影响其摩擦性能。为了充分了解影响外科结安全的因素,需要研究改变作用的本质,本研究用二种液体,一种含盐溶液,一种为浓缩甘油,此处分别称为润滑剂A和B,前一种是模拟机体环境中常规广泛应用的液体,后者是一种为了解高粘稠的液体对摩擦力影响适宜的润滑剂。试验分二阶段,首先作许多预备的试验,以建立用润滑剂能重复出结果的方法,缝线用messilene(聚酯纤维)。随后用这些方法作最后试验,目的为研究润滑剂对不同缝线摩擦性能的作用。资料与方法 Clinically applied sutures, which remain dry, sewed with body fat and body fluids rarely at the time of suturing a wound or at a post-operative stage, alter the surface properties and affect the tribological properties. In order to fully understand the factors affecting the safety of the surgical knot, we need to study the nature of the change. In this study, two liquids, one salt solution and one glycerin concentrate, are referred to herein as lubricants A and B, respectively Simulates liquids commonly used in the body environment, the latter of which is a lubricant that is suitable for understanding the effect of highly viscous liquids on friction. The test was divided into two phases, starting with a number of preliminary tests to establish a method of repeating the results with a lubricant, using a messilene (polyester fiber) suture. These methods were then used as a final test to study the effect of lubricants on the frictional properties of different sutures. Materials and Methods
