| 摘 要： | 目的通过对天鹅型记忆加压接骨器(swan-likememorycompres-sionconnector,SMC)进行力学测定,分析相关记忆生物力学意义。方法分别选取成人尸体湿肱骨,制作骨折模型,包绕压敏胶片后以SMC固定,测定加压支和环抱支固定骨折时的应力值。结果环抱支与肱骨接触部位的应力范围是2.42～22.68N,而SMC加压支在骨折断面产生的应力较大区的压应力为13.6MPa左右。结论SMC的环抱支应力有利于固定骨折两断端,加压支在骨折断面形成的应力场有利于骨折的愈合。

| Abstract: | Aim To analyze the memeory biomechanica l significance of swan-like memory compression connector(SMC)by means of biomechanical determination of SMC.Meth ods Twenty wet corpse adult humerus from a man dying of acute cranial brain inj u ry were used to make fracture mod-els.The fracture humerus was fixate d with SMC surrounded by prescale to find out the stress of holdong part an d compress ion part.Results The stress range of holding part contacting with humerus was 2.42-22.68N,and the stress in the fracture surface produ ced by compr ession part was about 13.6MPa.Conclusion The holding part plays a role in f ixating the fracture part of humerus,and the compression part produces the stre ss in the fracture surface which enhances the healing o f fracture. |
