摘　　要：医用高频电刀通过刀头尖端电弧放电并产生热量完成组织的切割和止血工作,是外科手术中的重要工具。在手术过程中,高频电刀温度过高会使血液和软组织脱水结痂甚至炭化,粘连并包覆刀头,进而对手术过程和医疗效果产生严重影响。为能够有效解决医用高频电刀表面的生物组织粘连问题,国内外诸多学者开展了电刀表面的脱附性研究,具有明显疏血、散热降温、抗组织粘附等效果的仿生脱附性医用高频电刀已成为该领域的研究热点和重要发展方向。按照现有脱附性医用高频电刀的结构特点进行归纳分类并详细介绍其研究和应用现状,着重介绍和分析仿生高频电刀的动植物脱附模型,总结国内外关于高频电刀表面脱附结构或涂层的制造方法,分析讨论目前脱附性医用高频电刀所存在的问题,最后对其未来的发展趋势进行展望。As an important tool in surgical operation,surgical electromes are used to perform tissue cutting and hemostasis by discharging arc at the tip of the electromes and generating heat.In the process of surgery,over-high temperature of electromes make the blood and soft tissue dehydrate to form a scab even carbonize.Therefore,the electromes’head are adhered and covered,making a serious impact on the surgical process and medical effects.In order to effectively solve these problems,many scholars at home and abroad carry out studies on the surface adhesion of electrotomes.Some bionic desorption surgical electrotomes with obvious effects of anti-blood,thermolysis,anti-tissue-adhesivity and so on become a research hotspot and an important development direction in this field.The existing desorption electrotomes are classified according to the structural characteristics,and its research and application status are introduced in detail.Then the animal and plant desorption models of bionic electromes are emphatically introduced and analyzed,as well as the manufacturing methods of desorption microstructures on electromes’surface are summarized.Furthermore,the problems on exist the current desorption electromes are analyzed and discussed,and it is also proposed that more endeavors should be attempted to what in the future.
