在2018版医疗器械分类目录中，结构组件为刀片和刀柄，用途为对人体或动物体组织进行切割的特制刀具，称为手术刀，作为外科手术中的手术工具不可或缺，至关重要。下面就让小编带您了解一下手术刀的发展历史和结构用途。

手术刀的发展历史

1973年，经专家考证，世界上zui早的手术刀为出土于河北藁城台西村商代遗址的第4号墓葬中的“砭镰”，到今天为止已经有大约3400年了。

19世纪末和20世纪初，由于不断完善的麻醉和输血技术，现代外科手术的质量也获得了显著的提高，手术器械持续得到改进，制作工艺的进步也相当大，材质也从铁质演变成不锈钢、钛、铬、钒等。

手术刀的结构用途

一般由刀片和刀柄共同构成手术刀，刃口以及与手术刀柄对接的安装槽一般会为刀片所具有，纯钛、钛合金、不锈钢或碳钢材料一般为刀片所采用的材质，通常为一次性的。将皮肤和肌肉切开为解剖时刀刃的用途，修洁血管和神经为刀尖的用途，钝性分离为刀柄的用途。按照创口大小需要对刀片及刀柄的型号进行选择，选择适合的。因为切割后对组织“零”损伤的特性为普通手术刀所具有，所以在各种手术中均能够被应用，然而其切割后创面出血活跃，应当在出血较多的手术中控制性的应用。

以上即为手术刀的发展历史和结构用途。
