摘　　要：骨穿针外固定技术是治疗骨折、严重的肢体损伤和残缺及重建患肢功能的一种主要方法,而应用最多最广的、以六自由度并联结构为基础的泰勒固定架仍存在无法实现数字化调节、数字化测量,以及本身结构缺陷等问题。设计了一种六连杆式数字化骨外固定器控制系统,使用了不同于泰勒支架结构的六自由度并联结构,利用PLC运动控制器、光栅传感器对骨外固定架进行改造设计,从而实现固定器的数字化调节及测量,由此解决当前临床使用中遇到的各种问题。Bone piercing external fixation technique is one of the main methods to treat fracture,severe limb injury and disability and to rebuild the function of the affected limb,but the most widely used Taylor bracket based on the six degrees of freedom parallel structure is still unable to achieve digital adjustment,digital measurement,and its own structural defects and other problems.A six-link digital external bone fixator control system is designed,which uses a six-degree-of-freedom parallel structure different from the Taylor bracket structure,and uses a PLC motion controller and encoder sensor to modify the design of the external bone fixator,so as to realize the digital adjustment and measurement of the fixator,thus solving the various problems encountered in current clinical use.

关 键 词：骨外固定 数字化调控 六自由度并联
