摘要/Abstract

摘要： 高频电刀因其优良的切割效率和止血性能在微创手术中得到了广泛的应用，但组织粘刀和创面碳化，不利于术后愈合引发手术事故。如何解决高频电刀的粘刀和创面碳化损伤是载能手术器械面临的重要技术难题，超声振动优异的减粘降附性能为本研究提供了创新灵感。首先通过分析超声振动对高频电刀与切割组织极间电场和多能场组织去除机制的影响，提出超声振动的机械作用会加速组织去除。通过软组织载能切削试验测试了超声振动辅助高频电刀的防粘性能以及组织热损伤，试验结果证实了超声振动辅助高频电刀的组织粘附量减少了约80%，无黑色焦痂组织，切割伤口齐整，热损伤面积减小了约50%，满足了微创载能器械的手术技术要求。

Abstract: The electrosurgical electrode has been widely used in minimally invasive surgery due to its excellent cutting efficiency and hemostatic properties. However, tissue adhesion to the electrode and carbonization of the wound surface are not conducive to postoperative healing. Inspiration from the excellent anti-adhesion performance of ultrasonic vibration gives new insights into the design of a novel electrosurgical electrode to minimize tissue adhesion to the electrode. Firstly, by analyzing the mechanism of the influence of the ultrasonic vibration on the electric field and the mechanism of tissue removal under multi-energy fields, it was found that the mechanical force of ultrasonic vibration will accelerate tissue removal. Finally, the energy-based cutting experiments reveal that the cutting performance of ultrasonic vibration assisted electrosurgical electrode is significantly improved, for example tissue adhesion mass decline by 80%, 50% for thermal damage area reducing. The ultrasonic vibration assisted electrosurgical electrode satisfied the surgical technical requirements of energy-based minimally invasive devices.
