手术器械的质量除外观质量是电镀、机械加工等合适外,还要求具有一是的强度、硬度、弹性、冲击韧性等力学性能,这些性能的获得,决定于用料与热处理工艺的正确与否,也就是内在质量。热处理这个不改变器械外形,只改进器械内在质量的工种,往往为人们所忽视。当前我们医疗器械工业产品内在质量的不稳定,“三类品”的形成,很多就是因为热处 The quality of surgical instruments in addition to the appearance of the quality of electroplating, machining and other suitable, but also requires one with the strength, hardness, elasticity, impact toughness and other mechanical properties, these properties are obtained, depending on the material and heat treatment process is correct or not , That is, intrinsic quality. Heat treatment does not change the shape of the instrument, only to improve the inherent quality of the instruments, often overlooked by people. At present, the inherent quality of our medical device industrial products is unstable. The formation of “three types of products” is often caused by heat
