目的:通过离体猪后足屈肌腱修复模型评估一种新型内置式肌腱连接器修复肌腱效果。方法:用猪后足趾深屈肌腱模型，对于同一猪后足的第2、3趾分别采用内置可吸收连接器(实验组)或双津下法(对照组)予以缝合，采用Instron5848微观力学实验系统记录和分析2 mm间距形成时拉力负荷、屈服点负荷、最大抗拉负荷、修复刚度。对于取材自同一猪后足的第2、3趾测试差值采用配对n t检验分析。n 结果:内置连接器法抗拉强度显著高于双津下法，其中2 mm间距形成负荷差值为(17.93±8.66) N(n t＝7.169，n P<0.01)，屈服点负荷差值为(12.73±6.66) N(n t＝6.148，n P<0.01)，最大抗拉负荷差值为(22.06±12.43) N，差异均有统计学意义(n t＝6.622，n P<0.01)。n 结论:这种内置式连接器法是一种比较可靠的新型肌腱修复技术，为早期主动功能锻炼提供强有力的保障，有望减轻肌腱粘连。“,”Objective:To evaluate the efficacy of a new type of internal tendon connector in repairing tendon by porcine hindfoot flexor tendon model.Methods:The deep flexor tendon of pig hind toe was used as the object of repair, and the two flexor tendons of the same pig hindfoot were sutured with internal tendon connector method or modified double Tsuge method, respectively. The tension load of 2 mm spacing, yield point load, maximum tensile load and repair stiffness were recorded and analyzed by Instron5848 micromechanics experimental system. The difference between two tendons taken from the same pig hindfoot was analyzed by paired n t test.n Results:The tensile strength of the internal connector method was significantly greater than that of the modified double Tsuge method, in which the average load difference of 2 mm spacing, yield point and maximum tensile load were (17.93±8.66) N (n t=7.169, n P<0.01), (12.73±6.66) N (n t=6.148, n P<0.01) and (22.06±12.43) N (n t=6.622, n P<0.01), but there was no significant difference in tendon stiffness.n Conclusion:This internal tendon connector method is a new, reliable tendon repair technique, and may provide a strong guarantee for early active functional exercise, which can ameliorate the adhesion of tendon.
