Electrosurgical unit (ESU) analyzers automate the testing and inspection of the output circuits and safety features of ESUs. They perform testing that would otherwise require several other pieces of equipment, as well as considerably more time and greater technician expertise. They are used largely by clinical engineering departments for routine inspection and preventive maintenance (IPM) procedures and, less often, for accident investigations and troubleshooting. In this Evaluation, we tested three ESU analyzers from three suppliers. We rated all three analyzers Acceptable and ranked them in two groupings. In ranking the units, we placed the greatest weight on ease of use for routine ESU inspections, and gave additional consideration to versatility for advanced applications such as ESU research. The unit in Group 1 was the easiest to use, especially for infrequent users. The units in Group 2 were satisfactory but require more frequent use to maintain proficiency and to avoid user errors.
电外科设备（ESU）分析仪可自动对ESU的输出电路和安全特性进行测试与检查。它们能执行的测试，若用其他几件设备来进行，则需要更多时间，且对技术人员的专业知识要求也更高。临床工程部门主要使用它们进行常规检查和预防性维护（IPM）程序，较少用于事故调查和故障排除。在本次评估中，我们测试了来自三家供应商的三款ESU分析仪。我们将这三款分析仪均评为“可接受”，并将它们分为两组。在对这些设备进行排名时，我们最看重常规ESU检查的易用性，并额外考虑了其在ESU研究等高级应用中的通用性。第1组的设备最易于使用，尤其对于不常使用的用户。第2组的设备令人满意，但需要更频繁地使用以保持熟练程度并避免用户出错。
