摘要
介绍了一种长管骨干骨折治疗用微动外固定架的设计方案。该装置采用微型直流减速电机和螺杆传动,由单片机控制微动的幅度和频率,使骨折断端受到微动应力刺激,促进骨痂的形成和钙化,加速骨折愈合。该装置将被用于微动骨折治疗的研究。
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.
