Surgeon's Console: This is where the surgeon sits and operates the robot. It provides a high-definition 3D view of the surgical field and allows the surgeon to control robotic arms with precision.
-
Robotic Arms: These are the mechanical arms equipped with surgical instruments. The surgeon's movements are translated into precise movements of these robotic arms.
-
Patient-side Cart: This cart is positioned next to the patient during surgery and houses the robotic arms and surgical instruments. It is controlled remotely by the surgeon.
-
Vision System: The vision system provides a magnified, high-resolution, 3D view of the surgical area. It captures images in real-time and relays them to the surgeon's console.
