Description
技术领域technical field
本发明涉及一种踝关节挛缩牵伸支具，它是一种可自动调节关节角度治疗踝关节挛缩的康复支具，属于康复医疗设备技术领域。The invention relates to an ankle contracture stretching brace, which is a rehabilitation brace capable of automatically adjusting joint angles to treat ankle contracture, and belongs to the technical field of rehabilitation medical equipment.
背景技术Background technique
踝关节肌肉、韧带、骨骼发生损伤或者中枢神经系统损伤时，踝关节往往会因为长时间制动或废用而导致踝关节挛缩、变形，为了解决这一问题，需要通过牵引、拉伸踝关节周围的肌肉、韧带，以恢复踝关节的活动度。常用的康复医疗方式是靠自己牵伸或者在医生帮助下进行踝关节牵伸训练，也可以通过医疗器械的辅助进行康复训练。When the ankle muscles, ligaments, bones are injured or the central nervous system is injured, the ankle joint will often be contracted and deformed due to prolonged braking or disuse. In order to solve this problem, it is necessary to use traction and stretching of the ankle joint surrounding muscles and ligaments to restore ankle mobility. The commonly used rehabilitation medical method is stretching by oneself or with the help of a doctor for ankle stretching training, and rehabilitation training can also be performed with the assistance of medical equipment.
现有的踝关节康复医疗器械通常有两种形式：机械式和电气式。机械式能够很好地贴合人体关节，但通常需要人手动调节关节的活动量，这一工作一般由医生来完成，医生需要不断根据肌肉、韧带康复时间调整关节角度，不能够有效地大量使用；电器式往往结构简单，操作简单，不能很好地控制调整的幅度，不能保护踝关节的生理结构，牵伸过度往往造成肌腱和韧带的损伤。Existing medical devices for ankle joint rehabilitation generally have two forms: mechanical and electrical. The mechanical type can fit the joints of the human body very well, but usually requires people to manually adjust the amount of joint activity. This work is usually done by doctors. Doctors need to constantly adjust the joint angle according to the recovery time of muscles and ligaments, so they cannot be used effectively in large quantities. ; The electrical type is often simple in structure and simple in operation, and cannot control the adjustment range well, and cannot protect the physiological structure of the ankle joint, and excessive stretching often causes damage to tendons and ligaments.
在目前的研究中，河南中医学院的张斌等人在专利CN 203354852U中发明了一种电动液压踝关节校正板，该校正板可以有效解决提高牵伸小腿三头肌和跟腱的效果，增强疗效，提高工作效率，该校正板的两个液压伸缩杆上安装有一个控制手柄，可通过控制手柄控制关节角度在0～35°内可调，但该结构过于简单，不能很好地贴合人体踝关节，在使用中可能产生松脱的现象；吉林大学的李秋菊等人在专利CN 203425085 U中发明了可调式踝关节康复支具，该康复支具包括小腿固定器、足托组成，该结构踝关节处存在一个带螺孔的圆盘，可以通过该圆盘处的紧定螺钉固定关节小腿固定器和足托，控制一定的角度，该固定期的特点是能够很好地体和人体下肢的外形，通过固定带将肢体固定在支架上，但该康复支具需要靠医生手动调节关节角度，调节的过程中费时费力，比较复杂。综合以上现状，踝关节康复支具尚无一款可自动调节适用于实际医疗中的产品，本专利申请针对踝关节康复需求，设计了一种可自动调节踝关节角度实现牵伸踝关节周围韧带和肌肉，改善踝关节挛缩的康复支具，该支具能够自动调节踝关节牵引拉伸的角度，并锁定在相应的位置，帮助患者改善踝关节关节活动度、治疗踝关节挛缩。In the current study, Zhang Bin and others from Henan College of Traditional Chinese Medicine invented an electro-hydraulic ankle joint correction board in the patent CN 203354852U. Curative effect, improve work efficiency, a control handle is installed on the two hydraulic telescopic rods of the correction plate, and the joint angle can be adjusted within 0-35° through the control handle, but the structure is too simple to fit well Human ankle joints may become loose during use; Li Qiuju of Jilin University and others invented an adjustable ankle joint rehabilitation brace in the patent CN 203425085 U, which consists of a calf fixer and a foot support. Structure There is a disc with a screw hole at the ankle joint, through which the set screw at the disc can be used to fix the joint calf fixer and the foot support to control a certain angle. The shape of the lower limbs is fixed on the bracket through the fixing belt, but the rehabilitation brace requires the doctor to manually adjust the joint angle, and the adjustment process is time-consuming, laborious and complicated. Based on the above current situation, there is no product that can automatically adjust the ankle joint rehabilitation brace and is suitable for actual medical treatment. This patent application is aimed at the needs of ankle joint rehabilitation, and designs a device that can automatically adjust the angle of the ankle joint to achieve stretching of the ligaments around the ankle joint. And muscles, a rehabilitation brace for improving ankle joint contracture, which can automatically adjust the angle of ankle joint traction and stretching, and lock it in the corresponding position to help patients improve the range of motion of the ankle joint and treat ankle joint contracture.
