ABSTRACT
<p><b>OBJECTIVE</b>To verify the feasibility and safety of the vascular interventional vascular interventional surgical robot system applied to vascular interventional operation.</p><p><b>METHODS</b>From March to September 2013, 10 patients had undergone robot-assisted cerebral angiography. There were 6 male and 4 female patients; aged from 19 to 58 years, with an average age of 38.4 years. The operation were carried out by neurosurgeons and vascular interventional robot. After successfully implanted of femoral artery sheath by hand, the catheter was fixed on the robot, under the guidance of navigation image the surgeon manipulate the master part and control the slave part of robot by sending command through network transmission, finally finished the whole cerebral angiography. The operation time was recorded from placing the sheath into femoral artery to finishing cerebrovascular selective angiography, simultaneously the time of staff under exposure of X ray was recorded, and the position difference between the setted targets and the actual position(positioning accuracy).</p><p><b>RESULTS</b>It took 25-41 minutes to finish the cerebral angiography, the average time was (31 ± 5) minutes, and the robot-assisted angiography went quickly and smoothly without surgical complications. The remote positioning accuracy was (1.03 ± 0.23) mm. The time of staff under exposure of X ray was 0 minute, the entire experimental process was basically implemented mechanization and automation.</p><p><b>CONCLUSION</b>This system basically achieves initial medical purposes, such as reducing the radiation, facilitating interventional procedures on the basis of enhancing the image navigation, shorting the operation time, and improve the quality of operation.</p>

Objective To investigate the technical feasibility of medical robot in application to vascular intervention. Methods The independent-developed medical robot was used in the glass vessel model and vascular intervention experiments in a dog. Results The process of experiments were smooth,the system movement did not have any malfunction,and the animal experiments did not have any operative complications. The operative time was 50 minutes.Conclusions The medical robot can basically meet the requirements of cerebral angiography. It has laid a foundation for further development of intracranial vascular interventional procedures and clinical application.
