The cryoablation-robot features an organ positioning scanning device that scans the patient's organs in real time, identifies tumors, generates a three-dimensional image of the data, and guides the puncture robotic arm in position. Doctors can perform preoperative planning and surgery on a removable iPad, and can also view scanned 3D images in real time, perform surgical operations, and view ablation progress in real time. The device greatly improves the operating efficiency of doctors and reduce the consumption of medical resources.
