| Abstract: | The structure of a micromovement device for treatment of diaphyseal long bone fracture was presented in this paper. Mini DC motor and edge-cam gearing is used for power transmission. This device can quantitatively control the interfragmentary movement,so as to improve the forming and calcifying of callus and to enhance fracture healing. Edge-cam's working face is at the end of the cylinder. Edge-cam gearing is compact and reliable. When transmission force is low,the cam material may use plastic. In this paper,we choose polyethylene as the cam material. Because the friction coefficient between polyethylene and steel is low,0.05 only,the transmission efficiency is relatively high. We also analyzed the pushing stage of edge-cam gearing by way of modeling,and checked the transmission efficiency and axial force output. |
