背景 天鹅记忆接骨器在临床使用中取得了良好的疗效,并出现了"无骨痂、无应力遮挡"新的骨愈合现象.目的 电测分析天鹅记忆接骨器的临床作用.方法 通过贴片、标定,得到天鹅记忆接骨器的载荷-应变曲线,然后根据天鹅记忆接骨器固定新鲜人体肱骨的应变值,计算天鹅记忆接骨器的动态记忆持骨力值.结果与结论 天鹅记忆接骨器的鹅颈加压部、鹅体接骨板部、鹅翼持骨部三部相互协调,记忆持骨,其动态记忆持骨的生物学力值为110.35 N.提示天鹅记忆接骨器产生的动态记忆持骨力保证了早日去除外固定,早期功能锻炼,促进患肢康复.%BACKGROUND: Swan-like memorably-compressive connector (SMC) has received good efficiency in clinical application, and appears with new phenomenon of bone healing with no callus and no stress-shielding. OBJECTIVE: To electrometric analyze the clinical application of SMC.METHODS: Load-strain curve was obtained by sticking slice and standardization, then according to the strain value showed by strain gauge when the fresh humerus was fixated by SMC, the value of dynamic memorial force for holding bone was calculated.RESULTS AND CONCLUSION: The swan-neck compressive part, swan-body connective part, swan-wing holing part of the SMC were harmonized with each other, biological force values of the dynamic memorably holding the bone was 110.35 N. It is indicated that SMC has the dynamic memorably holding force providing guarantee for promoting external fixation removal, postoperative functional exercises and limb rehabilitation.
