robotic surgery
Laparoscopic cameras and robotic hands performing coronary artery bypass surgery in place of open-heart surgery.
In robotic surgical systems, such as the widely used da Vinci Surgical System, the surgeon controls the operation from a remote console rather than standing directly over the patient.
The surgeon operates using "master controllers" at this console to manipulate the robotic instruments and a binocular camera. These systems function as "slave" units, where the computer processes the surgeon's hand movements and translates them into precise actions performed by the robotic arms at the patient's side.
Key features of this control method include:
- Dexterity: The instruments are designed to mimic the movement of human wrists, allowing for greater precision in tight spaces.
- Tremor Elimination: The system scales the surgeon's movements, which helps eliminate unwanted hand tremors.
- Visualization: The surgeon views the procedure through a monitor that provides a three-dimensional image, with computer processing linking the visual field to the spatial positioning of the instruments.1
