ABSTRACT
Objective To design a CT-guided puncture positioning device to shorten puncture time while increase the accuracy. Methods The device realized 3D positioning by the principle of plane geometry, which was composed of a positioner,a fixation mechanism and a direction guiding mechanism for puncture needle.The positioner and direction guiding mechanism were made of transparent plastic, and the fixation mechanism was made of elastic cloth. Results The device gained advantages over the traditional means in puncture time,times of needle insertion and times of CT scanning,and had the puncture success rate in one time being 90%. Conclusion The device behaves well in focal positioning and puncture needle guiding,and thus decreases the probability of failed puncture and the patient pains.
