In robot–assisted surgery, with the da Vinci System (da Vinci Robot), a surgeon is able to manipulate the robot to perform controlled, surgical procedures, such as dissection and suturing. The main components of the da Vinci System include:
 

• A microscope that produces magnified 3D imagery so that the surgeon can see a high-definition representation of the internal organs, muscle tissues, and nerve endings.

• An ergonomically designed console, which allows the surgeon to sit before a 3D monitor to manipulate the robot during surgery.

• Wristed instruments that can bend and rotate in up to 7 directions. When used in surgery, a regular laparoscope is only able to move in 4 directions. The da Vinci System, therefore offers greater freedom of movement than the human hand, and as well offers higher precision and stability due to its anti-tremor technology.

• A patient-side cart, where the patient is positioned during surgery, designed especially for use with the da Vinci System.

To introduce the robotic instruments to the body, the surgeon will make 5 small incisions in the patient’s abdomen, around the navel area. The surgeon will then sit at the console for the duration of the surgery, and manipulate the arms of the robot via a monitor. The da Vinci System will transmit micro-scaled signals from the movement of the surgeon’s hands, which will then translate into microscopic, controlled movements of the robot arms operating in the patient’s body.

The da Vinci System has 4 arm instruments: Arm 1 is used to hold the 3D microscope that transmits images of the patient’s internal organs to the monitor; arms 2 and 3 are responsible for dissecting and suturing tissues; and arm 4 is responsible for moving the surrounding tissues, if necessary, to prevent interference and obstruction.
