摘　　要：目的针对手功能障碍患者,改进设计一种新型筷子辅具,以解决因肌力不足、精细动作困难等原因造成的用筷困难。方法采用掌控式横握操作、一体化结构设计、折弯冲压加工工艺,改进折弯连接处、筷柄等关键部位。进行有限元仿真分析,制作样机进行力学测试,由一例3岁男童试用。结果筷子辅具握持操作所需握力与折弯半径、材料、截面积和握持位置相关;握持操作对特定手指肌力和灵巧度的要求不高,使用时不易滑脱,两筷间有确定的相对运动,左右筷头能自动弹开,便于左手使用。结论本设计可解决手功能障碍患者就餐用筷问题,有助于患者提高生活质量,也适合于用筷经验不足的人士。Objective To design a new type of assistive chopsticks for the hand disorders,such as hand weakness and poor fine movement,etc.Methods The assistive chopsticks were palm-control operative,integrated structure designed,and bending stamping processing technology was adopted.The key parts such as the bends and joint,holding parts were improved.The prototype was tested with finite element analysis and mechanical testing,and used on trial by a three years old boy.Results The gripping force needed was related to the bending radius,material,section size and holding position.It required less dexterity and force for particular fingers,and was not easy to drop down.They could bounce off automatically and were suitable for left hand.Conclusion The new type of assistive chopsticks may help the patients with hand dysfunction to have meals with chopsticks,to improve the quality of life.However,it is also suitable for Westerners with less experience.
