摘　　要：目的设计小腿残肢负重压力取型系统实现全面承重的小腿假肢在取型中合理分配残肢末端的承重量。方法设计制作小腿假肢接受腔负重压力取型系统。6例患者均穿戴该方法制作的接受腔和传统手法取型制作的髌韧带承重接受腔,对比接受腔界面压力,评价取型效果。结果与髌韧带承重接受腔相比,使用本系统制作的接受腔承重更加均匀,在取型时就能完成对残肢的压缩和对残端压力的控制。结论负重压力取型技术可以制作全面负重的小腿假肢,提高接受腔适配性。Objective To design a weight-bearing pressure casting system for transtibial prostheses to make the total surface bearing socket and to control the stump and bearing during the casting process.MethodsThe weight-bearing pressure casting system was designed.6 cases weared the socket by this method and traditional patellar tendon bearing socket by hand casting.Socket interface pressure was compared,and the effect of casting was assessed.ResultsCompared with patellar tendon bearing socket,the socket pressure in the socked by this method was distributed more equally throughout the transtibial residual limb during the casting process,and completed the stumps compression and stump-end pressure control.ConclusionWeight-bearing pressure casting system can make the total surface bearing socket,and improve the fit of the socket.
