Development and calibration of an instrument for measuring the fatigue life of prostheses Part(Ⅰ)——Development of the instrument / 医疗卫生装备

Using eccentric wheel and spring, an instrument was developed in this study. Relative information of the instrument were clearly explained, including its structure and running principle. The instrument can be widely used in fatigue measurement of fixed prostheses and capability of resisting break, and provide the experimental gist of the using of prostheses.
