Compared with traditional lumens, robotic surgery has the advantages of precise operation, good flexibility, good visual imaging and comfortable operation. 1. Precise operation: the robotic surgical system utilizes a mechanical arm for operation, which can avoid the occurrence of hand tremor during manual operation, and the operation is more precise and can be carried out in a more subtle way. 2. Flexibility: It can avoid the problem of collision of instruments, and can realize automatic suturing and other operations, which saves the operation time. 3. Good visual imaging: 3D imaging technology is used in robotic surgery, with more accurate spatial positioning and clearer imaging. 4. Comfortable operation: During robotic surgery, the surgeon can sit on the operating table, avoiding the fatigue caused by standing for a long time and making the operation more comfortable.
