【摘要】：脊柱三維運動的研究對正確了解與評估脊柱的損傷及對脊柱的植入物手術(shù)等有重要的臨床指導意義。由于脊柱運動是三維空間六個自由度的耦合運動，模擬在體脊柱三維運動存在很大的挑戰(zhàn)。目前國內(nèi)外很多實驗室都研制了款式各異的脊柱三維運動試驗機，尚沒有統(tǒng)一的標準和規(guī)范。脊柱三維運動試驗機經(jīng)歷了從二維到三維，從手動控制到自動控制的發(fā)展過程。近年來，隨著脊柱外科學的發(fā)展，涌現(xiàn)出越來越多的脊柱運動測量方法與工具。根據(jù)脊柱的運動特性、生理特點及研究目的，選擇符合脊柱運動規(guī)律的的脊柱三維運動試驗機是非常必要的。本文旨在南方醫(yī)科大學南方醫(yī)院脊柱和脊髓損傷研究實驗室現(xiàn)有的脊柱三維運動試驗機的控制及檢測裝置等硬件基礎(chǔ)上，基于LabVIEW研制了一套脊柱三維運動試驗機控制系統(tǒng)，用來產(chǎn)生脊柱的前屈、后伸、側(cè)彎、側(cè)旋運動，實現(xiàn)脊柱六個自由度的運動特點，達到準確和便利的測量目的。 本文介紹了脊柱三維運動試驗機裝置的工作原理及應(yīng)用范圍;設(shè)計了基于阿爾泰采集卡、扭矩傳感器及力川伺服電機為基礎(chǔ)的脊柱三維運動試驗機裝置，基于LabVIEW開發(fā)平臺研制了脊柱三維運動裝置控制系統(tǒng);解決了三維運動試驗機的扭矩控制及角速率控制，并設(shè)置了控制系統(tǒng)的安全范圍，達到脊柱三維運動試驗機的使用目的。 實驗結(jié)果表明：基于LabVIEW的脊柱三維運動試驗機控制系統(tǒng)具有采樣速率快，，扭矩控制準確，使用方便，界面簡潔，具有可靠性高和易于維護等優(yōu)點。
[Abstract]:The study of three-dimensional motion of spine has important clinical significance in understanding and evaluating the injury of spine and in the operation of spinal implant. Because the spine motion is a coupling motion of six degrees of freedom in three dimensional space, there is a great challenge in simulating the three dimensional motion of the spine in vivo. At present, many laboratories at home and abroad have developed different types of spine three-dimensional motion testing machine, there is no unified standards and specifications. The three-dimensional motion testing machine of spine has experienced the development from two-dimensional to three-dimensional, from manual control to automatic control. In recent years, with the development of spinal surgery, more and more spinal motion measurement methods and tools have emerged. According to the motion characteristics, physiological characteristics and research objectives of the spine, it is necessary to select a three dimensional spine motion testing machine which accords with the spine motion law. The purpose of this paper is to develop a control system of spine three-dimensional motion testing machine based on LabVIEW based on the existing control and detection device of spine and spinal cord injury research laboratory in Nanfang Hospital of Southern Medical University. It is used to produce flexion, extension, lateral bending and lateral rotation motion of the spine, so as to achieve the motion characteristics of six degrees of freedom of the spine and to achieve accurate and convenient measurement. This paper introduces the working principle and application scope of the spine three-dimensional motion testing machine, and designs the spine three-dimensional motion testing machine device based on Altay acquisition card, torque sensor and Lichuan servo motor. Based on the LabVIEW development platform, the control system of spine three-dimensional motion device is developed, the torque control and angle rate control of three-dimensional motion testing machine are solved, and the safety range of control system is set up to achieve the purpose of using the three-dimensional spine motion testing machine. The experimental results show that the control system based on LabVIEW has the advantages of high sampling rate, accurate torque control, convenient use, simple interface, high reliability and easy maintenance.
