Abstract The purpose of this study is to improve the cutting performance of the scalpel by imitating the micro-structures of miscanthus leaves. Four different types of micro-serrated edges were designed, and these micro-serrations were then successfully processed on the edges of the scalpels by laser induced plasma micromachining (LIPMM). Subsequently, cutting tests were carried out to explore the effect of micro-serrations on the cutting performance. Compared to the unprocessed commercial scalpel, the micro-serrated scalpels could significantly reduce the cutting force and actual cutting depth. The type of blended serration without spacing scalpel had the best performance during cutting soft tissue due to the induced serration effect, which was also verified by the cutting process images and finite element simulation.

基于芒叶仿生微锯齿手术刀的制备及切割性能

摘要 本研究旨在通过模仿芒草叶片的微观结构来提高手术刀的切割性能。设计了四种不同类型的微锯齿边缘，然后通过激光诱导等离子体微加工 (LIPMM) 在手术刀的边缘成功加工这些微锯齿。随后，进行了切削试验，以探索微锯齿对切削性能的影响。与未加工的商业手术刀相比，微锯齿手术刀可以显着降低切割力和实际切割深度。由于诱导锯齿效应，无间距混合锯齿型手术刀在切割软组织时性能最佳，切割过程图像和有限元仿真也验证了这一点。
