Robotic Surgery is different in several ways.
First, the Camera used in Robotic surgery is a High definition 4K - 3D Camera. This enables the surgeon to have a precise and clear view of the operating field. The surgeon is also in control of the camera at all times. In traditional laparoscopic surgery an assistant holds the camera and runs it for the surgeon.
Second, the instruments used by the surgeon can move and maneuver in a more precise manner than even the human hand. The instruments can turn and rotate in ways our hands and laparoscopic instruments cannot.
Lastly, given the improvement in visualization and instrumentation we can do difficult and complex cases that were not as feasible laparoscopically. These can be done safer and faster leading to improved recovery time and less use of pain medication and return to work faster.
