Abstract

本发明属于医疗器械领域，涉及膝关节的固定及其实际功能评估，具体涉及用于评估膝关节功能的膝关节角度固定器。本发明将红外标记球应用于膝关节角度固定器中，通过电脑收集红外信号，通过对信号的分析评估膝关节的实际功能，结果客观公正，为法医鉴定膝关节实际功能丧失程度提供科学判断证据。

Description

一种用于评估膝关节功能的膝关节角度固定器
技术领域
本发明属于医疗器械领域，具体涉及用于评估膝关节功能的膝关节角度固定器。
背景技术
对比国内外下肢各大关节功能评定的方法，如果下肢各大关节的功能作用总和等价于下肢整体的功能作用，则意味着各大关节的功能作用互相独立，彼此没有交集，各自的作用整合在一起才相当于下肢整体的功能作用（见图2）。然而，事实上下肢各大关节的功能作用应当具有协调性与互补性，下肢整体的功能作用可能同时依赖于各大关节的功能作用，即膝关节的功能作用一定程度上可能影响髋关节或（和）踝关节的功能作用，如此设想则下肢各大关节的实际功能作用可能会大于原先“互相独立”的关节功能作用，也就是说此时下肢整体的功能作用并不等于下肢各大关节功能作用的简单相加（见图3），下肢各大关节的功能作用可能都非常重要，不因为髋关节功能的重要而使踝关节功能的重要性降低。这一理念从国外对于复合型损伤的功能丧失评估计算公式中可以猜想，即复合值=A+B×（100%-A）。因此，希望直接对各大关节的实际功能作用进行评估、测算。本发明首次引入红外技术对膝关节的实际功能进行评估测算。
发明内容
本发明的目的是提供一种用于评估膝关节功能的膝关节角度固定器及其使用方法。
本发明的技术方案如下：
1、一种用于评估膝关节功能的膝关节角度固定器，其特征在于，所述固定器包括固定臂（1），分布于固定臂两端的固定带（2），所述固定带用于绑定大腿和小腿，在固定臂的中间位置设有用于调节固定角度的中央刻度盘，中央刻度盘的中间及固定臂两端的最外侧设有红外标记球凹槽（4）。
2、一种如权利要求1所述的膝关节角度固定器在评价膝关节实际功能中的用途。
3、一种使用如权利要球1所述的膝关节角度固定器进行膝关节实际功能测定的方法，其特征在于，所述方法包括以下步骤：（1）将配备有红外标记球的膝关节角度固定器固定于受试者膝关节，并将角度先调节至膝关节功能位；（2）嘱其完成.以Fugl-Meyer下肢运动功能评价表为基础设计的运动方案；（3）再将角度分别调节至膝关节极屈位与伸直位，分别完成上述运动方案；（4）通过膝关节角度固定器上的红外标记球将红外信号传输至计算机，导出角度、位移等数据，评价膝关节对于下肢的功能作用。
有益效果：本申请首次将红外线技术引入法医膝关节功能评估领域，动态监测并评估下肢关节的协调运动功能。和传统的评估方法相比，本申请程序简单易操作，成本低，所获得的数据可信度高，且整个评估过程耗时短，可以快速完成评估，，满足法医鉴定要求。

具体实施方式
实施例1
（1）将配备有红外标记球的膝关节角度固定器固定于受试者膝关节，并将角度先调节至膝关节功能位；
（2）嘱其完成.以Fugl-Meyer下肢运动功能评价表为基础设计的运动方案；
（3）再将角度分别调节至膝关节极屈位与伸直位，分别完成上述运动方案；
（4）通过膝关节角度固定器上的红外标记球将红外信号传输至计算机，导出角度、位移等数据，评价膝关节对于下肢的功能作用。
（5）将导出的角度、位移数据与Fugl-Meyer下肢运动功能评价表正常值范围进行比较，以正常值作对照，计算出活动功能的丧失比例，即为该膝关节在下肢的功能作用。
