NE-Ⅳ型碎石机是由科达公司生产的。碎石机打一个结石病人,电极就报废,消耗量大。能否把电极放电端的间隙重新调整(标准:0.38mm±0.02mm),继续使用呢?先做模拟体外碎石试验,发现不但使电极再生利用,而且碎石效果也不差。下面介绍自制电极间隙微调器的方法。 NE-Ⅳ type lithotripter is produced by Kodak Company. Crusher hit a stone patient, the electrode scrapped, consumption. Can the electrode discharge end of the gap readjustment (standard: 0.38mm ± 0.02mm), continue to use it? First do simulation of extracorporeal gravel test and found that not only the electrode regeneration and utilization, and the gravel effect is not bad. The following describes the homemade electrode gap trimmer method.
