An image guided orthopedic surgery robot system

Abstract

In long bone fracture therapies performed by robotic surgical systems,the locking of intramedullary nails has presented a major challenge.To improve results,an orthopedic robot system and image navigation technology were studied.After correcting the distortion of X-ray images,the local contrast was enhanced,and a targeting method was proposed that is based on a geometric model to get a 3D path in order to guide the series robot to lock the intramedullary nail. Additionally,this system includes virtual surgery simulation software and a tele-operation subsystem,which can monitor the surgery process and allow surgeons to control robots remotely.Experimental results indicate this system has sufficient positioning accuracy and stability,and can dramatically decrease operating time and radiation doses.
