【摘要】:隨著經(jīng)濟(jì)的快速增長(zhǎng),工礦企業(yè)增多,交通運(yùn)輸事業(yè)迅速發(fā)展,發(fā)生事故增多,由此每年會(huì)產(chǎn)生大量的四肢骨折及骨干畸形患者。目前,內(nèi)固定是治療四肢骨折的主要方式之一,內(nèi)固定會(huì)破壞骨端愈合的微環(huán)境,干擾骨的生理性愈合及骨改進(jìn),存在內(nèi)固定失效及二次骨折的風(fēng)險(xiǎn)。當(dāng)對(duì)多種原因?qū)е碌闹w畸形及肢體殘疾進(jìn)行治療時(shí),內(nèi)固定多數(shù)變得無(wú)能為力,不能獲得滿意的矯正效果。因此研發(fā)一種復(fù)位、固定的微侵襲性骨外固定器提供快速有效的治療,順應(yīng)骨外科發(fā)展趨勢(shì),具有廣闊的市場(chǎng)前景。 文章介紹了一種新型的骨外固定器順應(yīng)性多功能骨外固定器。主要包括以下兩方面內(nèi)容:(1)高精度順應(yīng)性多功能骨外固定器,對(duì)支撐桿、骨外固定針的固定夾進(jìn)行了優(yōu)化設(shè)計(jì),調(diào)節(jié)精度達(dá)到0.33mm,,同時(shí)減輕了患者痛苦,提高了治療效果;(2)配套軟件的開(kāi)發(fā),提出了一種正解算法并應(yīng)用于處方的計(jì)算,該算法具有方法簡(jiǎn)便、編程易實(shí)現(xiàn)、初值易選取、計(jì)算速度快、求解精度高等優(yōu)點(diǎn)。 通過(guò)實(shí)驗(yàn)室的框架演練證明了軟件系統(tǒng)的有效性及實(shí)用性;最終,通過(guò)初步的臨床驗(yàn)證得到了預(yù)期的治療效果。
[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.
