1从AO传统加压接骨板到新型内固定器原则显示文摘骨折内固定中生物学的重要性和保护骨和软组织,作为AO的第4项原则已受重视。AO传统加压接骨板对骨面的压迫会干扰骨皮质的血运,引起接骨板下方骨的结构性改变。有限接触动力加压接骨板(LC-DCP)可减小接骨板和骨的接触面积。锁定螺丝钉(LHS)、点接触固定器(PCFix)及微创固定系统(LISS)设计则因接骨板与骨面无接触和压迫,是新的一次变革。这种内固定器原理的概念可以用外固定支架来理解,可以防止任何对骨血运的破坏,其稳定性依赖于螺丝钉-接骨板组合的成角稳定性。带有锁定螺丝钉的新型微创固定系统(LISS)和锁定加压接骨板(LCP)可以为现代骨折手术治疗提供新的选择方法,是微创经皮接骨板技术(MIPO)的理想材料,并可以在疏松骨质内得到相当好的固定强度。然而,必须指出这些新型接骨板和螺丝钉并不能解决所有的问题,特别是在处理干骺端和骨干部骨折时,它们每一步的操作都需要有非常仔细的计划,包括重温AO经典的原则。Thomas P.Rüedi(托马斯.鲁迪) Christoph Sommer(克利斯托夫.邵墨) 罗炯 顾立强 2003中华创伤骨科杂志2003,5,3:169
2PDC钻头的水力设计和轮廓是减少泥包的关键显示文摘通过大量的实验数据论述PDC钻头的水力设计和轮廓造型与钻头产生泥包的关系。提出具有抛物线轮廓和刮刀式水力设计的聚晶金刚石(PDC)钻头在页岩地层中不易产生泥包,而采用脊式布齿或开放式表面水力设计的PDC钻头或平/圆轮廓PDC钻头则相反。同时,指出PDC钻头的水力设计对钻头泥包的产生具有更大的影响。赵佩华 P.R Hariharan 1997国外石油机械1997,8,5:10
3Wettability Modification for Biosurface of Titanium Alloy by Means of Sequential Carburization显示文摘Microporous titanium carbide coating was successfully synthesized on medical grade titanium alloy by using sequentialcarburization.Changes in the surface morphology of titanium alloy occasioned by sequential carburization were characterizedand the wettability characteristics were quantified.Furthermore,the dispersion forces were calculated and discussed.The resultsindicate that sequential carburization is an effective way to modify the wettability of titanium alloy.After the carburization thesurface dispersion force of titanium alloy increased from 76.5×10-3J·m-2 to 105.5×10-3 J·m-2,with an enhancement of37.9 %.Meanwhile the contact angle of titanium alloy decreased from 83° to 71.5°,indicating a significant improvement ofwettability,which is much closer to the optimal water contact angle for cell adhesion of 70°.Yong Luo~(1,2) Shi-rong Ge~1 Zhong-min Jin~21.Institute of Tribology and Reliability Engineering,School of Material Science and Engineering,China University of Mining and Technology,Xuzhou 221008,P.R China2.Institute of Medical and Biological Engineering,School of Mechanical Engineering,University of Leeds,Leeds LS2 9JT,UK 2009Journal of Bionic Engineering2009,6,3:6
