In order to guarantee its clinical use safety, this paper designed a quality control detection method for ultrasonic scalpel. Methods Based on the analysis of the structure of ultrasonic scalpel and the mechanism of biological effect on human body, this paper selected key performance parameters and detected by waveform analysis. Results The test parameters were calculated and compared with the design standard, and a complete set of quality control check sample was given in this paper. Conclusion This method is practicable and the test results are repeatable. Key words: ultrasonic scalpel; quality control test; driving frequency; electric safety; thermal effect of ultrasound [中图分类号] TH777 [文献标识码] B doi：10.3969/j.issn.1674-1633.2017.10.024 [文章编号] 1674-1633(2017)10-0089-04 引言 生产的Harmonic 超声刀以及日本Olympus 生产的SonoSurg 超声手术刀具有出血少、对周围组织伤害少、术后恢 手术刀等。本论文以Harmonic超声手术刀作为研究对象， 复快等特点，其作用于人体组织以蛋白质凝固为效果终点， 其换能形式为压电式，谐振频率55.5 kHz。目前新型号的 不会引起组织干燥、灼伤等副作用，刀头工作时也没有电 超声刀可以同时连接超声刀头和高频刀头，分别输出超 流通过人体，在手术室中有着广泛的应用。
