The success rate of lung biopsy under CT guidance is always a serious difficulty in clinical work, especially the focus of a special part, if the biopsy operation is incorrect or fails, the accuracy of the biopsy is affected, and the probability of complications is increased. The success or failure of the puncture is determined by two factors, namely the depth of penetration and the angle of penetration.
The optimal needle insertion point and the optimal needle insertion depth and angle can be determined on the chest wall after CT scanning, but the actual needle insertion angle is often judged by intuition of an operator, and when a smaller or deeper focus is punctured, the target point cannot be accurately punctured due to slight deviation of the needle insertion angle, and at the moment, the needle insertion angle is adjusted again, so that the risks of bleeding, pneumothorax and the like are greatly increased. In addition, the puncture method is easily affected by the breathing motion of the patient, and the puncture needle swings due to unstable fixation after entering the tissue, so that repeated puncture and CT scanning are required in the operation, and the structure of the auxiliary fixing device for the puncture operation is necessary to be researched and improved.
