【摘要】：隨著人口老齡化的推進(jìn),生活節(jié)奏的加快,交通事故、自然災(zāi)害、工傷事故使人類遭受外部傷害概率大大提高。而脛骨骨折是最為常見的骨折病例。本課題針對脛骨骨折康復(fù),開發(fā)了一套用于康復(fù)訓(xùn)練的智能支具(包括負(fù)重支具和智能鞋墊),并探究了一種骨折愈合程度的測量系統(tǒng)。首先,根據(jù)小腿解剖學(xué)特征、骨折康復(fù)要求,設(shè)計(jì)了一款負(fù)重可調(diào)支具。并通過對接受腔建模,探究了摩擦力在承重中的作用。其次,根據(jù)足底力分布和人體行走步態(tài)規(guī)律,提出了智能鞋墊方案用于檢測支具減重效果。采用薄膜傳感器檢測足底力,分別設(shè)計(jì)上位機(jī)與下位機(jī)。經(jīng)過必要的傳感器標(biāo)定后,通過正常行走步態(tài)驗(yàn)證智能鞋墊可行性。隨后,利用超聲橫波作為評價(jià)骨折愈合程度的方案。根據(jù)超聲折射理論選取儀器、探頭與配套電路。并對發(fā)射功率電路中各元器件的選型對激勵效果的影響做了探究。通過實(shí)驗(yàn)驗(yàn)證了系統(tǒng)可激勵出能在骨中傳播的超聲橫波。最后,通過實(shí)驗(yàn)驗(yàn)證了各子系統(tǒng)的功能。采用智能鞋墊對兩種異常步態(tài)和正常步態(tài)做對比,獲取了每種異常步態(tài)與正常步態(tài)足底力的差異；通過智能鞋墊驗(yàn)證了負(fù)重支具在站立相和行走相中的減重效果；利用超聲波檢測離體牛股骨,驗(yàn)證了超聲評價(jià)骨愈合的可行性。綜上,本文設(shè)計(jì)了由負(fù)重支具和智能鞋墊組成的智能支具,并設(shè)計(jì)了一款超聲波檢測骨折愈合的系統(tǒng)。通過實(shí)驗(yàn)探究了上述系統(tǒng)的可行性與實(shí)用性。
[Abstract]:With the advance of population aging, the quickening of life rhythm, traffic accidents, natural disasters and industrial accidents, the probability of human being suffering from external injury is greatly increased. Tibial fractures are the most common fracture cases. For the rehabilitation of tibial fractures, a set of intelligent brace (including load-bearing brace and intelligent insole) was developed for rehabilitation training, and a measuring system of fracture healing degree was explored. First of all, according to the anatomical characteristics of the leg and fracture rehabilitation requirements, a load adjustable support is designed. By modeling the acceptance cavity, the effect of friction on load bearing is explored. Secondly, according to the foot force distribution and human walking gait rule, the intelligent insole scheme is put forward to detect the weight loss effect of braces. The plantar force was measured by thin film sensor, and the upper and lower computers were designed respectively. After the necessary sensor calibration, the feasibility of intelligent insole was verified by walking gait. Subsequently, ultrasonic transverse wave was used as a method to evaluate the degree of fracture healing. According to the theory of ultrasonic refraction, the instrument, probe and matching circuit are selected. The influence of the type selection of each component on the excitation effect in the transmission power circuit is also discussed. The experimental results show that the system can excite the ultrasonic transverse wave which can propagate through the bone. Finally, the function of each subsystem is verified by experiment. Two kinds of abnormal gait and normal gait were compared with intelligent insole, and the difference of foot sole force between each abnormal gait and normal gait was obtained, and the weight loss effect of weight-bearing brace in standing phase and walking phase was verified by intelligent insole. Ultrasonic detection of isolated bovine femur proved the feasibility of ultrasonic evaluation of bone healing. In summary, an intelligent bracing consisting of load-bearing braces and intelligent insoles is designed, and a ultrasonic detection system for fracture healing is designed. The feasibility and practicability of the system are explored through experiments.
