How the da Vinci Si Works

The da Vinci Si

The da Vinci Si has two separate but connected sections:

The tower, which is positioned directly over the patient during surgery, contains the robot’s four arms—three that can hold a multitude of different surgical instruments, and a fourth that holds the system’s 3-D cameras. These arms are controlled by a computer that exactly replicates the movements of the operating surgeon.

The console is where the surgeon sits and operates the robot’s controls while looking into a stereoscopic monitor that provides a magnified, high definition 3-D view of the surgical site. The surgeon manipulates the robot’s four arms by maneuvering two master controls that provide fingertip precision of movement.

The surgeon also operates a footswitch that provides additional options, such as the ability to switch between two different energy sources. Touchpads allow the surgeon to easily adjust video, audio and system settings, while the ergonomic console and the alignment of the controls and monitor are designed to keep the surgeon in a relaxed, focused position at all times.

Finally, additional video screens link in the rest of the surgical team by providing a two-dimensional view of what the surgeon is looking at through the da Vinci’s stereoptic monitor.
