Description
技术领域
本发明属于医疗器械领域,涉及纠正膝关节失稳状态的装置,尤其是一种多位同步施力的膝康机。
背景技术
膝关节病是我国发病率较高的疾病之一,在气候寒冷的北方地区尤甚。中老年人由于骨骼退行性改变,双膝关节完全健康的占比相当之低;年轻人由于运动损伤或运动方式不当、运动过量,患有膝关节病的也有一定数量。膝关节病的主要症状表现为疼痛、积液、关节卡顿、骨刺增生、活动受限等,严重的表现为骨骼变形、行走困难、难以自主蹲起、不能正常上下楼梯,以至于生活质量下降,甚至生活不能自理。
纠正膝关节失稳通常采取药物或手术治疗方式,药物及微创手术治疗着眼于消除炎症、去除骨刺、积液、创伤破坏等病变,以达到缓解病情,减轻疼痛、一定程度恢复功能的目的,但是没有针对膝关节失稳的纠正。只能采用膝关节置换手术,通过对股骨胫骨进行截骨后植入假体来达到纠正失稳解除病痛的目的。但是,膝关节病是反复发作的顽症,每逢天气转冷或有一定诱因就会发作,每次治疗病人既要承受巨大的痛苦,又要负担少则数千多则上万的医药费,只是鲜有治愈的希望。
对于膝关节的病害顽症,需要反复长时间的药物治疗,对于身体脏器的损害是不可避免的。手术治疗的身体伤害如骨骼截断、筋膜肌肉的破坏,手术后遗症如感染、深静脉血栓、关节松动不稳等,都会严重影响生活质量。关节假体使用寿命为15年,病人有再次置换的可能,而且10万-30万的手术费用和手术后遗症对患者是个很大的经济压力和精神压力。因此,对于膝关节的保健康复的技术创新,是十分必要的,社会需求量很大。
通过公开专利文献的检索,发现如下五篇与本专利申请相关的专利:
1、膝关节康复仪(cn110494111A),包括:大腿固定单元,***需要康复的腿中的大腿部分来进行固定;小腿固定单元,与上述大腿固定单元相邻配置,***上述需要康复的腿中的小腿部分来进行固定;以及膝盖位置引导件,配置于上述大腿固定单元与上述小腿固定单元之间,当向上述大腿固定单元和上述小腿固定单元***上述需要康复的腿时,引导膝盖的位置。
2、一种膝关节康复装置(cn105853147B)。涉及理疗器械领域,尤其涉及针对膝关节康复装置的改进。提出了一种结构精巧、使用方便且稳定性好,使用时可针对不同腿长的人进行适当调节,并辅以小腿肌肉按摩的膝关节康复装置。所述脚板撑架竖直设置、且滑动连接在基座的顶面上,所述脚板的脚跟部铰接在脚板撑架的顶端;所述主驱动装置包括相互连接的驱动杆和动力源,所述动力源固定连接在基座内,所述驱动杆竖直设置、且其顶端伸出至基座上方,所述膝关节托板固定连接在驱动杆的顶端、且在动力源的驱动下沿竖直方向做直线往复运动;在进行膝关节康复时,可对小腿肌肉进行良好、有效的按摩。本发明整体上具有结构精巧、使用方便且稳定性好的特点。
3、一种膝关节康复器(cn208372101U),其包括:安装架;摆动臂,其可转动地连接在所述安装架上,所述摆动臂的一端连接有第一伸缩杆,所述摆动臂的另一端连接有第二伸缩杆,所述第二伸缩杆的端部连接有至少一个脚部固定器;锁紧定位结构,其具有定位盘及锁紧机构,在所述锁紧机构锁紧固定于所述定位盘的状态下,所述摆动臂能相对所述安装架被锁紧固定。本发明的膝关节康复器,能为患者进行膝关节弯曲练习和膝关节压直练习,其结构简单,操作使用方便。
4、一种膝关节康复仪(cn104771304B)。其特征在于包括膝关节按摩支架、护膝轮盘支架、护膝轮盘驱动电机、驱动齿轮、从动齿轮、驱动轴、护膝驱动轮盘、护膝摆动轮盘和抓手,膝关节按摩支架插接设置在前支架上,护膝轮盘驱动电机设置在膝关节按摩支架中部驱动两侧的驱动齿轮,一对护膝摆动轮盘对称设置在护膝轮盘驱动电机两侧,抓手设置在护膝摆动轮盘下方。本发明通过抓手对膝关节按摩理疗,能够促进血液循环和放松肌肉;该膝关节康复仪实用性强,可进行广泛推广使用;该膝关节康复仪核心元件为机械部件,可靠性好,寿命长。
5、一种膝关节康复装置(cn208388944U),涉及膝关节康复技术领域,包括牵拉装置、角度测量装置、牵引固定装置和悬吊器;所述牵拉装置用于安装在患肢上,所述角度测量装置用于测量患者的弯曲角度;所述悬吊器用于悬吊患肢;所述牵引固定装置固定在人体上,所述牵拉装置上设置有与牵引固定装置连接的牵拉绳。本发明提供的膝关节康复装置的牵拉装置与牵引固定装置连接,患者将患肢悬吊在悬吊器上,牵拉装置改变牵拉绳放卷的长度,实现对患者的膝关节的牵拉,同时角度测量装置能够测量患者膝关节屈曲的角度,精确控制膝关节的屈曲的角度,对恢复和锻炼膝关节的灵活性有很大的帮助。
通过技术特征的对比,上述的公开专利与本专利申请的发明目的及技术方案不相同。

下面结合实施例对本发明进一步说明:下述实施例是说明性的,不是限定性的,不能以下述实施例来限定本发明的保护范围。
一种多位同步施力的膝康机,由底箱11、立箱1及悬箱2构成,底箱一侧端竖直设置立箱,该立箱上端横向固装悬箱;底箱下底四角安装有万象滚轮10,以实现整个机构的移动;在底箱外侧设置有一连接桌9,用于患者8躺卧;底箱内安装有按压单元摆杆机构,立箱内安装有震动单元、牵拉单元及按压单元的传动机构;悬箱上安装有活动绑带3,该活动绑带用于捆扎患者小腿;在悬箱外端同轴安装一固定轴辊4,在该固定轴辊上安装一固定绑带5,该固定绑带用于固定捆扎患者大腿,参见图4。此外,在底箱上还安装有患者膝盖两侧对称设置的两个按压竖杆6及大腿两侧的两个横向拉紧卡扣7。
本发明的总体内部结构参见图4,立箱内的震动单元通过减速电机12驱动拨叉13摆转,拨叉上端固装一同轴安装在悬箱内的辊筒15,辊筒随同拨叉的摆转而同步摆动,活动绑带固装在该辊筒上随同摆转,摆转角度为0°±60°,最佳的摆动角度为±25°-±40°度。由于固定绑带固定住患者大腿,活动绑带产生角度摆转,不但实现了患者大腿的悬吊,促进血液循环,还使得患者膝盖部位得到有规律的扭转及震动,促进患者膝关节的锻炼及恢复。此外,立箱内的牵拉单元由减速电机20驱动,同时牵拉两个牵引带杆16来轴向扯拉患者小腿,而患者大腿两侧的两个横向拉紧卡扣连接大腿轴向定位绑带18,可以捆扎患者大腿而使之轴向定位,实现膝关节的拉直锻炼恢复。在立箱内的按压单元的传动结构是采用辊筒摆转驱动底箱内的按压单元的摆杆机构,通过摆转患者小腿两侧对称设置的两个按压竖杆,该两个按压竖杆共同卡扣连接一仿形膝关节的魔术扣17扣住患者膝关节方式,实现对患者膝关节部位的按压,纠正膝关节的失稳状态,消除由其带来的各种不适,阻止了膝关节病的发生。因此,本发明申请是将悬吊、震动、牵拉、按压对患者膝关节进行同步施力,克服了现有技术中,仅对膝关节的单一施力可能造成的患者膝关节损伤,实现对膝关节的有效康复训练,综合康复效果十分完美。
下面对上述各单元的具体结构,进行详细描述。
一、震动单元的结构,参见图5、6,减速电机安装在立箱内所固装的支架26上,该减速电机的驱动轴27同轴固装一转盘25,该转盘的盘面外侧平行向固装一销轴24,该销轴的外端同轴安装一转轮23;在悬箱内横向安装轴辊,该轴辊的里端通过固装在悬梁内的轴承座21采用轴承22安装,轴辊的外端安装在悬箱上,且该位置的悬箱外与轴辊同轴固装固定轴辊;在轴辊里端固装一拨叉,该拨叉的下部制有一导向长通孔28,该长通孔内可导向运行销轴的转轮,转轮可采用轴承或者类似产品制作,由此实现在转盘转动时,拨叉随销轴的圆周运动而实现向两侧的摆转,由此带动轴辊的摆转运动。
二、按压单元的结构,参见图7、8,在震动单元拨叉外侧的轴辊上,同轴固装一凸轮盘29,该凸轮盘为倒心型结构;在凸轮盘下端安装一竖直移动杆35,该竖直移动杆的下端铰装在一铰架横梁33上,该铰架横梁的两侧分别铰装一下摆杆31,该两个下摆杆的里端分别通过铰轴32铰装在铰架19上,该下摆杆的外端通过铰轴30分别与按压竖杆铰装。为了保证竖直移动杆的竖直位移,该竖直移动杆加装一竖直导套34;为保证竖直移动杆保持与凸轮盘的柔性贴合位移,竖直导套上端的竖直移动杆上还套装一回复弹簧14。
当辊筒摆动时,凸轮盘同时摆动,凸轮盘的凸起部位按压竖直移动杆并使在回复弹簧的作用下竖直移动杆贴合凸轮表面,竖直移动杆上下位移由此带动下摆杆以铰架为轴上下摆动,下摆杆外端铰装的两个按压竖杆也竖直上下位移,实现对患者膝关节部位的按压训练及恢复。
三、牵拉单元的结构,参见图9、10、11,在立箱内还固装另一减速电机20,该减速电机的输出轴同轴安装一主动齿轮36,该主动齿轮还啮合一相同结构的从动齿轮43,主动齿轮及从动齿轮的外盘面上均固装一绳轮盘37,该两个绳轮盘上均缠绕有一牵拉带40;在绳轮盘下方的横向支架42端部悬臂固装有一横梁,该横梁的端部均固装一导向轮39;绳轮盘的两条牵拉带分别通过该两个导向轮分别与小腿两侧的牵引带杆卡扣连接。为了保证牵引带运行的导向顺畅,在两个导向轮与各自的绳轮盘之间均还安装有一竖向导向套38,在导向轮与牵引带杆之间也安装有一横向导向套41。
上述结构可实现:减速电机旋转,带动相互啮合的两个齿轮旋转,安装在齿轮上的绳轮盘旋转,此时安装在绳轮盘上的牵拉带向上拉动,由于导向轮的作用,使牵拉带拉伸患者的膝关节部位,以调理训练膝关节的失稳状态。
