Abstract

Abstract:

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.

Key words: hand dysfunction, assistive chopsticks, structure design
