声面肌电图监测系统是将肌电反应放大,通过扩音器变成声信号反馈到医生,术中对面神经功能进行监测保护面神经。1984年开始在听神经瘤手术中应用。监测系统有二个电极,一个手持的阴极探头,另一个为阳极,放在对侧耳部前方,用每秒6次,0.01ms短脉冲刺激。面肌活动记录从放入肌内的双极电极引出,肌电反应经放大后引入手术室的扩音器发出声音,用电视磁带将手术步骤、声音反应和
Surface EMG monitoring system is to enlarge the EMG response, through the microphone into a sound signal feedback to the doctor, surgery to monitor facial nerve function to protect the facial nerve. 1984 started in the application of acoustic neuroma surgery. The monitor system has two electrodes, one hand-held cathode probe and the other an anode, placed in front of the contralateral ear, with a short pulse of 0.01 ms, six times per second. Facial muscle activity records from the bipolar electrode into the muscle leads to EMG amplification by the introduction of the operating room loudspeaker to make a sound, the use of television tape to the surgical procedures, the sound response and
