二、背景技术2. Background technology
随着我国人口老龄化逐渐严重，生活环境的污染与恶化，生活节奏加快，中风患者在逐年增加，并且呈现年轻化趋势，同时各种交通工具的增多、工业的快速发展，造成脑外伤、手部外伤患者也在增加，康复训练对患者脑神经的代偿和重组起着至关重要的作用。With the aging of the population in our country, the pollution and deterioration of the living environment, and the accelerated pace of life, the number of stroke patients is increasing year by year, and they are showing a younger trend. Patients with internal trauma are also increasing, and rehabilitation training plays a vital role in the compensation and reorganization of patients' cranial nerves.
现有的手指康复器械大部分采用驱动患者的远端指关节，而中间指关节和掌指关节没有被束缚，导致患者在手指康复运动过程中，手指变形，降低康复效果，甚至在手指变形的康复训练过程中较小的拉力就会拉伤患者四指。本两关节牵引手指康复训练器采用牵引掌指关节和远端指关节，中间指关节处于两关节中间被带动一起运动，不仅手指康复训练过程中不会变形，而且提高了患者四指康复训练的舒适度。Most of the existing finger rehabilitation devices use to drive the patient’s distal knuckles, while the middle knuckles and metacarpophalangeal joints are not restrained, causing the patient’s fingers to deform during the finger rehabilitation exercise, reducing the rehabilitation effect, and even when the fingers are deformed. A small pulling force in the rehabilitation training process will strain the patient's four fingers. This two-joint traction finger rehabilitation training device adopts the traction of the metacarpophalangeal joint and the distal knuckle. The middle knuckle is in the middle of the two joints and is driven to move together. Not only does the finger not deform during the rehabilitation training process, but also improves the patient's four-finger rehabilitation training. comfort.
