椎弓根手术中电子导航系统的研制

摘要

This paper introduces the design and implementation of electronic navigation in the operation of pedicle based on bio-impedance method The system can detect the resistance between the two electrodes in order to provide navigation for the operation of pedicle. A low consumption and portable type instrument was designed based on MSP430 Micro Controller Unit (MCU). Animal experiment has proved that it can make better performance in the reduction of interference noise.%本文介绍了椎弓根手术中电子导航系统的设计与实现.系统采用生物阻抗法,通过检测两电极间的电阻值的变化,为椎弓根手术提供导航.样机基于MSP430单片机,实现了低功耗便携式设计.对样机的动物实验表明,系统运行稳定,抗干扰能力强.
