Description

一种可更换电极刀体的手术电刀笔 技术领域
本发明涉及医疗器械附属装置的技术领域，特别是涉及一种电极可更换的手术电刀笔。
背景技术
手术电刀笔，是通过电流来摧毁病变组织的高频电刀，并不是单纯的加热电极或刀头造成的，它是将高电流密度的高频电流聚集起来，直接摧毁处于与有效电极尖端相接触一点下的组织，当与有效电极相接触或相邻近的组织或细胞的温度上升到细胞中的蛋白质变性的时候，便产生凝血，这种精确的外科效果是由波形、电压、电流、组织的类型和电极的形状及大小来决定的。
常规手术中使用的手术电刀笔是带有普通电极的，不进行吸烟操作。
在进行某些手术操作例如切割凝血的过程中往往会产烟雾，因此有些手术电刀笔上连通有吸烟管。为了满足对可吸烟电刀笔的技术使用需求还特别推出了吸烟管可伸缩的手术电刀笔，其临床意义是为了满足不同深浅的手术部位的需求，可以方便医生在手术过程中根据手术部位的不同随时调节吸烟管的长度，保证吸烟效果。但同时为了保证医生手术操作视野，一般来说，吸烟手术电刀笔的电极长度比普通电极短。
因此，基于不同的手术要求和手术环境，需要使用不同种类的手术电刀笔。但是现有的手术电刀笔结构要么是带有普通电极的手术刀，要么是常规的吸烟手术电刀笔，没有可方便更换的非吸烟的普通电极手术电刀笔和吸烟手术电刀笔，从而影响手术方便快捷使用，而且造 成吸烟管的浪费。
