Description

踝关节松弛测定仪
技术领域
本实用新型涉及一种医疗诊断器械,具体来讲涉及一种踝关节松弛测定仪。
背景技术
踝关节不稳是踝关节损伤的常见症状,常见于踝关节损伤急性期没有得到正确的诊断及及时治疗的患者。如果不进行及时正确的处理,踝关节周围的韧带得不到修复而松弛,整个踝关节周围的肌力下降,以及本体感受器的损伤导致患踝出现反复扭伤的“恶性循环”,严重影响运动员的训练、比赛和普通人的生活质量。
踝关节扭伤是在外力作用下,关节骤然向一侧活动而超过其正常活动度时,引起关节周围软组织如关节囊、韧带、肌腱等发生撕裂伤,称为关节扭伤。轻者仅有部分韧带撕裂、重者可使韧带完全断裂或韧带及关节囊附着处的骨质撕脱,甚至发生关节脱位;因此怎样及时反馈踝关节稳定程度是有效避免发生踝关节扭伤的重点。
实用新型内容
本实用新型所要解决的技术问题是提供一种结构简单合理,能及时诊断出踝关节稳定程度的踝关节松弛测定仪。
本实用新型所提出的技术问题是这样解决的:一种踝关节松弛测定仪,所述测定仪主要由基座以及分别安装于基座两端端部的主机和位移测定机构构成,所述主机上设置有力传感器和位移传感器。
所述力传感器设置于主机面向传动测定机构的一侧,与该力传感器位于同一侧的主机上还设置有固定人体胫腓骨下端的固定支架,主机的另一侧设有摇臂,摇臂由传动螺杆连接于主机上。
所述位移测定机构主要是由脚部承托板、滑轨和滑轨固定座连接构成,所述滑轨固定座固定于基座上,滑轨连接固定于滑轨固定座之间,所述脚部承托板下端设有与滑轨相连接滑动配合的滑动座。
所述脚部承托板上端的两侧设有侧板,该侧板上开设有调节脚部承托板倾斜高度的高度调节槽,该高度调节槽上设有调节旋钮。
所述主机的顶部设有控制面板。
本实用新型的工作原理是:踝关节松弛测定仪是根据踝关节前抽屉试验原理设计,模拟踝关节前抽屉试验,得出前抽屉试验的定量结果。固定支架固定胫腓骨下端,以恒定的速度转动摇臂带动传动螺杆,其上的力传感器向跟骨施压,推动跟骨和距骨同时前移,力传感器测定所施加的力量,位移传感器测定跟骨和距骨相应的位移,MVAD卡采集力传感器和位移传感器信号,采样频率50Hz,计算机以图形方式实时显示关节所加外力及位移。
综上所述,本实用新型结构简单合理,能够快速、定量、无创测试踝关节稳定程度;为病患踝关节不稳的诊治提供有力的依据。
