Abstract：Objective To explore the clinical value of MAXIOTM robotic three-dimensional targeting system in lung puncture biopsy guided by CT.Methods Between August and September 2017, 40 patients were randomly divided into the experimental group and control group. The experimental group adopted the MAXIOTM robotic three-dimensional targeting positioning system in the CT guided descending pulmonary puncture biopsy, while the control group was guided by the traditional grid locator to conduct the puncture biopsy. The average length of operation, one-time puncture success rate, scanning frequency, complication rate and biopsy pathological diagnosis rate were compared between the two groups.Results The average length of operation of lung puncture in the experimental group and control group was (24.0±3.9) min and (27.3±4.1) min respectively, so the difference between the two groups was not statistically significant(t=-1.91,P>0.05). The one-time puncture success rate of the experimental group and control group was 75% (15/20) and 25% (5/20)respectively, suggesting that the difference between the two groups was statistically significant(χ2=8.10,P<0.05). The average scanning times of the experimental group and the control group were (4.1±0.5)times and (6.0±1.3)times respectively, and the difference between the two groups was statistically significant(t=-4.65,P<0.05). The incidence of complications was 10% (2/20) and 40% (8/20) respectively in the experimental group and the control group so that the difference between the two groups was statistically significant(χ2=4.68, P<0.05). The positive rate of test in the experimental group and the control group was 100% (20/20) and 90% (18/20) respectively, so the difference between the two groups was not statistically significant (χ2=2.05,P>0.05).Conclusions The MAXIOTM robotic 3D targeting system can accurately plan the puncture path before CT-guided lung biopsy. The real-time stereotactic operation of the robot arm can improve the success rate of disposable puncture, thus reducing the times of scans, radiation dose and complications.
