中文摘要:
      为解决当前单一的弯曲/ 伸展辅助运动的软体康复手套不能提供手部完整的运 动动作支持,对脑卒中后肌张力异常导致的手部运动障碍康复效果欠佳,设计了一种新的 纤维强化并联腔道式软体驱动器(SPA)结构,该结构能够在三路组合压力驱动下实现三维方向致动,实现 对手部伸展/ 弯曲、外展/内收、对掌/复位及其复合动作的支持。 通过对手部基本动作元的分析,设计了新的驱动器结构,利用有限元工具对设计参数进行了验证,并建立了运动学描述模型;给出了新驱动器的制备方法,并对制备的新驱动器进行了加载测试和软体康复手套样机操作测试。 测试结果表明,所设计的驱动器能够实现复合运动模式下的多指协同动作,支持手部运动多模式的辅助康复,并显著提升患者手部敏捷交互操作能力。
英文摘要:
      To solve the issue that the existing soft rehabilitation gloves only with flexion/ extension function cannot provide full range motion support, which is not good for the rehabilitation of hand movement disorders caused by abnormal muscle tone after stroke. A new fiber-reinforced parallel cavity-type soft pneumatic actuator (SPA) is designed. The new SPA can realize three-dimensional actuation under 3-channel pressures, supporting complex motion of ex-tension/flexion, abduction/ adduction and adduction/ abduction. In this research, first, based on the analysis of ac-tion elements of human hand, a SP A structure is designed, then design parameters are verified using a finite ele-ment analysis tool and kinematic modeling is also established. Then, the preparation method of SPA is given. Load tests of SP A and manipulation tasks of a fabricated soft glove are conducted. The results show that a glove with the designed SP As can realize cooperative finger motions under complex actuation mode, and supports full range of fin-ger motion assistance, which significantly improves patients' manipulation dexterity.
