Developmentof micromovement external fixture for treatment of bone fracture / 医疗卫生装备

ABSTRACT

The s tr ucture of a micromovement external fixture for treatment of diaphyseal long bo ne fracture is presented in this paper.Minisize DC geared motor and screw drive are used to transmit the power.Micro controller is used to control the micromove ment extent and frequency.This device can give the fractured bone ends micromo vement stress stimulation,so as to improve the forming and calcifying of the ca llus,and to accelerate the fracture healing process.This device can be applied t o the research on micromovement treatment of bone fracture.
