文题释义:
三维建模:是指设计人员直接从三维概念和构思入手,借助三维设计软件构建虚拟的三维模型来仿真分析和评价设计方案的可行性与可靠性等问题。通过三维建模设计产品,一方面可将抽象的概念和构思快速转化为可视化的图形;另一方面,通过可行性分析和评价能够显著提高方案设计、改进的效率。文章借助Creo三维设计软件设计了虚拟的手部康复训练装置,并利用该软件中的运动分析模块对模型的运动性能进行了仿真分析,通过虚拟技术验证了设计方案的可行性。
康复训练:康复训练是康复医学的一个重要手段,主要是通过训练方法使患者患肢恢复正常的自理功能,达到治疗效果。传统的康复训练采用的是人工康复训练方法,需要康复治疗师对患者进行手把手的重复性训练,训练效率较低且会占用治疗师大量的时间,使治疗师无法专注于治疗方案的改进和优化。文章针对康复训练中存在的上述问题,开发设计了一种自动化的康复训练装置,以期实现对患者手部的康复训练并将治疗师从繁重的康复训练中解脱出来。
 
摘要
背景:现有的人工康复训练方法效率较低,且会占用治疗师大量的时间,使治疗师无法专注于治疗方案的改进和优化。
目的:针对存在手部运动障碍的患者,设计了一种用于康复训练的手部康复训练装置。
方法:基于对手部的运动功能分析,得出了掌指关节与指间关节的活动范围,并在此基础上对手部康复训练装置进行设计,主要包括外骨骼执行系统的设计和控制检测系统的设计,最后对设计完成的训练装置进行了运动学仿真分析。

结果与结论:①仿真结果表明,虽然手部康复训练装置的指节活动范围与人手的测试轨迹之间存在一定的误差,但最大差值仅为5.13 mm,且结构设计中预留有调节余量,可有效弥补上述差值;②此外,该手部康复训练装置的每个指部件均由气缸单独控制,可用于辅助患者完成某些简单的日常生活活动能力;③试验设计的手部康复训练装置能够帮助患者完成简单的抓握动作和拿捏动作,且与现有的康复设备相比,传动机构较简单、质量较轻、穿戴轻便,具有较强的实用性特点,可用于患者的手部康复训练。

Abstract:

BACKGROUND: The existing artificial rehabilitation training method has low efficiency, and it would take a lot of time, so the therapist cannot focus on the improvement and optimization of treatment.

OBJECTIVE: To design a hand rehabilitation training device for the patient who has hand movement disorder.
METHODS: Based on the analysis of hand movement function, the range of motion of the metacarpophalangeal and interphalangeal joints was obtained, and the hand rehabilitation training device was designed. The device mainly included the exoskeleton executive system and control test system. Finally, the designed device was used for kinematics simulation.
RESULTS AND CONCLUSION: (1) The simulation results showed that the hand rehabilitation training robot’s knuckle range and trajectory had a certain error to human, but the maximum difference was only 5.13 mm. Moreover, the designed adjustment allowance could effectively compensate for the difference. (2) Moreover, each component of the hand rehabilitation training device was controlled by cylinder, and could help patients to complete simple daily life activities. (3) The designed hand rehabilitation training device could help patients to complete simple grasping, holding and kneading. Compared with modern rehabilitation device, the hand rehabilitation training device was simple, lighter weight and wearable. It has good practicability and can be used for hand rehabilitation training.
