Abstract: Vascular puncture interventional surgery is a modern minimally invasive treatment method, which punctures the target vein and inserts guide wire to accurately reach the affected area for treatment. It has the characteristics of little trauma, fast recovery and high safety. However, due to the different depth of the vessel, it is difficult to locate and accurately puncture the target vessel in puncture interventional surgery. Current puncture devices are not suitable for emergency vasculature access in non-clinical settings due to their size and weight. We designed a portable ultrasound-guided robot for venous puncture. The robot observed the venous tube through ultrasonic equipment, aligned the ultrasonic image, puncture needle and target venous tube through mechanical structure, and realized venous puncture at different depths by adjusting the moving distance up and down. The robot is small and lightweight, making it portable for use in non-clinical conditions. Experiments show that compared with conventional puncture methods, the robot can reduce patient trauma, reduce the difficulty of operators, and improve the success rate of vascular puncture.

Key words: minimally invasive surgery, vascular puncture, ultrasonic guidance, portable surgical robot
