一种用于膝关节前交叉韧带损伤辅助测量装置的研制

Design and development of auxiliary measurement device for knee anterior cruciate ligament injury

目的 :设计一种用于膝关节前交叉韧带损伤的辅助测量装置,用于提高专科查体准确率和术后生物力学功能康复评估。方法:该辅助测量装置基于病理解剖学与机械力学原理设计,由主架、支撑垫块2个部分组成。主架作为"桥梁"结构,平行横于胫骨上方,在其垂直方向上负载测量尺,为数据测量提供支持;支撑垫块作为"桥墩",分别固定于胫骨和髌骨,主要作用是提供反向用力,辅助测量。结果:使用该装置辅助测量,初诊成功率高于传统专科查体方法,效果显著。结论:该装置具有简单、实用、制作成本低廉等特点,值得在广大医院骨科推广应用。

Objective To design an auxiliary measurement device for anterior cruciate ligament injury in order to improve the accuracy of specialist examination and postoperative functional assessment. Methods The device consisted of a main frame and support pads, which was designed based on the principles of anatomopathology and mechanical mechanics. The frame was set above and paralleled to the tibia, and the measurement scale was put at the vertical direction of the frame. The support pads were fixed to the tibia and patella respectively to execute auxiliary measurement by providing opposite acting force. Results The success rate of preliminary diagnosis by the device was higher than that by traditional method. Conclusion The device gains advantages in convenience, practicality, low cost and etc, and is worthy promoting in the orthopedics department.
