医用电子仪器广泛应用于神经外科手术,如脑电图机、A、B型脑超声波诊断仪、颅内压监护仪、高频电刀机等。由于医务人员往往对电器设备性能不够熟悉,手术室没有专用地线系统和屏蔽室,遇有意外情况时,就会引起严重电击事故,或损坏精密电子仪器设备。鉴于上述情况,手术中使用电子仪器时,应具有基本要求和注意事项: (一)医用电子仪器使用不当,会发生几种电流生理效应。 1.高频电刀机使用不当,高频电流以热量
Medical electronic instruments are widely used in neurosurgery, such as EEG, A, B-type brain ultrasound diagnostic apparatus, intracranial pressure monitor, high frequency electric knife machine. As medical staff are often not familiar with the performance of electrical equipment, the operating room does not have a dedicated ground system and shielded room, in case of unexpected circumstances, it will cause serious electric shock, or damage to precision electronic equipment. In view of the above, the use of electronic instruments in surgery should have the basic requirements and precautions: (A) medical electronic devices used improperly, there will be several current physiological effects. 1. High-frequency electric knife improper use of high-frequency current to heat
