[0003] 5见有的手术刀具为了实现照明效果， 通常采用外部照明的技术方案。 换而言之
， 在手术刀柄的外部接近电极位置处安装 1个或多个 LED灯珠， 从而将光线投射 到手术部位。 然而， 上述外部照明的技术方案存在缺陷， 简述如下。
[0004] 其一， 无论在手术刀柄的外部安装多少个 LED灯珠， 由于各个 LED灯珠均为点 射， 因此叠加形成的照明环境仍然存在阴影。
[0005] 其二， 如需提高照明亮度， 需要安装较多的 LED灯珠， 直接提高手术刀具的占 用空间， 影响手术视野。
[0006] 其三， LED灯珠固定安装于手术刀柄， 因此 LH）灯珠无法随电极伸缩而同步伸 缩。 LED灯珠距离电极的有效作用部位较远。 如果更换长电极或者电极伸出之后 ， 照明效果直线下降并且阴影更为严重。
[0007] 其四， 5见有的手术刀具无法同时解决无阴影、 照明、 吸烟、 伸缩的共存问题。
常见的手术刀具只能在照明、 吸烟， 照明、 伸缩或者吸烟、 伸缩的三种功能搭 配之间选择。
