该句主干是there be结构，there are already robot systems，后面跟了定语从句that can perform some kinds of brain and bone surgery with sub-millimeter accuracy来修饰robot systems， thanks to the continual miniaturization of electronics and micro-mechanics为原因状语，而后面的破折号引出一个补充说明部分来修饰sub-millimeter accuracy。

由于电子和微型机械仪器不断小型化，现在已有一些机器人系统能够进行精确到亚毫米的.脑部和骨科手术，其精确性远远超过熟练的医生仅用他们的双手所能达到的水平。
