How Robotic Surgery Works

The Methodist Hospital offers robotic surgery using the da Vinci® Surgical System. This state-of-the-art system enables surgeons to perform major surgeries through a minimally invasive approach.

Using the da Vinci® Surgical system, the surgeon makes very small incisions, about the size of a dime, and inserts small surgical instruments attached to robotic arms. A tiny camera is attached to one of these instruments.

Sitting at a nearby console, with a magnified, 3D image of the operating field, the surgeon performs the surgery by controlling the robotic arms. The robotic arms mimic every movement of the surgeon’s hands, wrists and fingers, but with greater dexterity, precision and control than a human hand can achieve.

Leading-Edge Technology

The da Vinci® Surgical System is made up of 3 main components:

da Vinci Surgical System

  • The patient-side cart. Located next to the patient, this cart holds the robotic arms the surgeon uses to perform the procedure. Every movement is controlled by the surgeon.
  • The surgeon's console. There is where the surgeon sits to perform the surgery and view the image of the surgical site.
  • A 3-D Vision System. This component provides the surgeon a magnified, high-resolution, 3-D image of the surgical area, including an excellent view of the delicate tissue and organs, with the ability to zoom in and out.

Surgeon Benefits

The da Vinci® Surgical System enhances surgeons’ capabilities through benefits that include:

  • Enhanced view of the surgical site
  • Improved dexterity through the robotic arms
  • Greater surgical precision and accuracy
  • Improved access, eliminating the need for large, traumatic incisions
  • Increased range of motion, including the ability to rotate instruments more than 360 degrees through tiny incisions
  • Reproducibility, enabling the surgeon to repetitively perform technically precise maneuvers
