How does the surgeon see what he or she is doing?
The surgeon is able to visualize what he or she is doing through the da Vinci robot's vision system. One of the da Vinci system's robotic arms is created to hold the endoscopic cameras (it is like a flexible tube with camera and light at the end), which are introduced into the body through a tiny incision and send real-time images to the surgeon, seated at the system console.
The da Vinci robot is using two fiber optic cameras with 3D lens and high resolution, creating a real 3D color picture with a magnification of up to 10 times.
The surgeon seated at the console uses foot pedals to control the central robotic arm, which positions the cameras and lighting where it is needed. He can use two different cameras: a straight one and a 30-degree oblique camera to have better visibility.
Furthermore, the whole surgical team can see the operating field on the vision cart with the help of a large monitor, which provides a great visualization of the operation to the surgical assistant who is next to the patient.
The vision system of the da Vinci provides more than 1000 frames/sec of the instrument position and there is also a background noise filter for each image made by a video processor.
