【摘要】：随着经济的快速增长，工矿企业增多，交通运输事业迅速发展，发生事故增多，由此每年会产生大量的四肢骨折及骨干畸形患者。目前，内固定是治疗四肢骨折的主要方式之一，内固定会破坏骨端愈合的微环境，干扰骨的生理性愈合及骨改进，存在内固定失效及二次骨折的风险。当对多种原因导致的肢体畸形及肢体残疾进行治疗时，内固定多数变得无能为力，不能获得满意的矫正效果。因此研发一种复位、固定的微侵袭性骨外固定器提供快速有效的治疗，顺应骨外科发展趋势，具有广阔的市场前景。文章介绍了一种新型的骨外固定器顺应性多功能骨外固定器。主要包括以下两方面内容：（1）高精度顺应性多功能骨外固定器，对支撑杆、骨外固定针的固定夹进行了优化设计，调节精度达到0.33mm，，同时减轻了患者痛苦，提高了治疗效果；（2）配套软件的开发，提出了一种正解算法并应用于处方的计算，该算法具有方法简便、编程易实现、初值易选取、计算速度快、求解精度高等优点。通过实验室的框架演练证明了软件系统的有效性及实用性；最终，通过初步的临床验证得到了预期的治疗效果。
[Abstract]:With the rapid growth of economy, the increase of industrial and mining enterprises, the rapid development of transportation and accidents, there will be a large number of limb fractures and deformities every year. At present, internal fixation is one of the main methods for the treatment of extremities fracture. Internal fixation will destroy the microenvironment of bone end healing, interfere with the physiologic healing and bone improvement of bone, and risk the failure of internal fixation and the risk of secondary fracture. When various causes of limb deformity and limb disability are treated, most of the internal fixation becomes powerless and can not obtain satisfactory results. Therefore, the development of a reduction, fixation, micro-invasive external fixation device to provide rapid and effective treatment, follow the development trend of bone surgery, has a broad market prospects. In this paper, a new type of external bone fixator for compliance with multi-function external fixation is introduced. The main contents include the following two aspects: (1) High precision compliance multifunctional external fixator, the support rod, the fixation clip of external fixation needle were optimized, the adjusting precision reached 0.33 mm, at the same time, the pain of the patients was alleviated and the therapeutic effect was improved. (2) A forward solution algorithm is put forward and applied to the calculation of prescription. The algorithm has the advantages of simple method, easy programming, easy selection of initial value, high calculation speed and high precision. The effectiveness and practicability of the software system are proved by the framework exercise in the laboratory. Finally, the expected therapeutic effect is obtained through preliminary clinical verification.
