医疗用电动工具常见的有电动骨钻、牙钻、石膏电锯和电动胸骨锯等。这些医疗用电动工具基本上是借鉴手电钻功能改型设计而成,其电动机多数属于专用电动机,直接作用于各种功能工具,在使用时往往用手直接接触,为确保安全,必须采取可靠的接地保护,在检修时,除保持电动机原有的参数外,必须严格保持原有的绝缘水平与结构。因此,维修医疗用单相电动工具时,双重绝缘受损部位必须处理,并经耐压试验合格后方能进行重绕工序。不同极性的带电零件或带电体与非带电体之间应 Medical electric tools common electric bone drilling, dental drills, gypsum chainsaw and electric sternum saw and so on. These medical power tools are basically based on the modified design of a hand drill. Most of the motors are special motors and work directly on various functional tools. When in use, they often come into direct contact with hands. To ensure safety, a reliable Ground protection, overhaul, in addition to maintaining the original parameters of the motor, you must strictly maintain the original level of insulation and structure. Therefore, the maintenance of medical single-phase power tools, double insulated damaged parts must be dealt with, and after the pressure test passed before rewinding process. Live parts of different polarity or between live and non-live parts
