摘要
针对在骨科手术中,骨钻削时超过55℃会导致骨组织坏死甚至发生氧化,影响手术效果的问题,采用在针尖表面设计分屑槽等微结构的方法可以有效降低钻削温度。选用圆弧槽克氏针对骨进行钻削实验,通过单因素实验和多因素正交实验法,研究得出了圆弧槽长度、圆弧槽深度、圆弧槽与尖端距离3个圆弧槽克氏针结构参数对骨钻削温度及骨钻削力的影响规律及主次关系。建立了骨钻削温度及骨钻削力的预报模型,对经验模型的回归方程及系数进行了显著性检验,并对其进行参数优化,得出了结构参数的最优组合。
In orthopaedic surgery,bone drilling over 55 C will lead to bone tissue necrosis and even oxidation,affecting the effect of surgery.The drilling temperature can be effectively reduced by designing micro-structures such as chip grooves on the tip surface.By choosing Kirschner wire with arc groove for bone drilling experiment,single factor experiment and multi-factor orthogonal experiment method,the influence of structural parameters of Kirschner wire with arc groove(length of arc groove,depth of arc groove,distance between arc groove and tip)on bone drilling temperature and bone drilling force was studied and the primary and secondary relations were obtained.The prediction model of bone drilling temperature and force is established.The regression equation and coefficient of the empirical model are tested and optimized.The optimal combination of structural parameters is obtained.
