. . . In robotic-assisted surgery, the da Vinci robot is an extension of the surgeon’s hands in a way not previously possible with minimally invasive surgery via laparoscopy, he said.

“And that’s the key to its success,” Boggess added. “The robot takes us a big step beyond traditional laparoscopy. It allows us to operate more naturally, the way we do in open surgeries, but still preserve a minimally invasive approach with small incisions.”

As in laparoscopy, robotic surgery involves small incisions of one-fourth to three-fourths of an inch, into which sleeves are inserted as ports for placement of specialized instruments and a video camera.

“Robotic surgery allows us to virtually place our hands inside the patient without the need for large incisions,” Boggess said.

After sleeve placement, the robot, much like a post with three arms, is wheeled over and its center arm docked to a port that holds the camera and the other arms docked to the instrument ports.

However, surgery with the da Vinci does not mean close proximity to the patient. Unlike with laparoscopy, the surgeon is seated across the room from the patient, with arms inserted into the nearby console, fingers on stirrup-like holders and eyes fixed on lenses for sharp magnified images of the surgical site. Focus is adjusted via foot pedals.

While laparoscopy allows manipulation of instruments up, down and side-to-side, surgery with the da Vinci allows more natural wrist movement.

The robot’s arms have wrists with eight degrees of freedom that allow the surgeon “to bend around corners and work in ways that are much more natural,” said Boggess. This allows full range of motion and the ability to rotate instruments 360 degrees through tiny incisions. Direct and natural hand-eye instrument alignment is similar to open surgery, with “all-around” vision and the ability to zoom in and out.

Another advantage with da Vinci is the elimination of tremor. Surgeons can scale, or ratio, their finger movement to that of the robotic instrument. A movement of inches at the console can be scaled down to centimeters in the patient.

“This can re-introduce precision in an elderly surgeon, who has all those years of experience but has lost some dexterity,” Boggess said. . .

    On of Jackson’s (Mississippi) hospitals has the da Vinci. Personally, I’d love to see the safety traps and underpinnings of a mechanism of this nature not to mention the hands and minds that interface with it.

    […] The advantage of the system is numerous to both patient and surgeon. It allows the surgeon to virtually place their hands inside the patient without the need for large incisions. This minimizes the chances of the surgeon making a mistake that could harm the patient or even cause fatality. At the same time, it also helps patient to heal faster due to the smaller incisions. Another advantage is that surgeons can now scale, or ratio, their finger movement to that of the robotic arms. A movement of inches at the console can be scaled down to centimeters in the patient. This gives great control and precision to the surgery. The system also re-introduces precision to an elderly surgeon, who has all those years of experience but has lost some dexterity. The world first surgery using this system could be viewed here . via:1, 2 […]

    My fiance is 46 and has been diagnosed with prostate cancer. With his age and genetics a big factor we are looking at a radical prostatectomy. We live in Louisville, Kentucky and their is one da Vinci robotic arm. Surgeons have only been using it for one year here and I would like to know if there are more experienced surgeons in the US. I would like a better rate of success than 75%. I would appreciate any positive or negative comments and perhaps a surgeon’s name to contact.

    Thank You, Joni

    With almost 50% of all prostatectomy’s being done this year by the da Vinci robot it is hard to say that it is not effective. Docotrs who have done nothing but open surgery for years are now converting 100% of all of their cases to da Vinci surgery and this is not just in urology, but GYN, Bariatric Surgery, and CV surgery. This is a proven technology that allows the surgeons to be better than they already are (3d vision, fully articulating instruments, and intuitive movement) and allows patients to have the results of open surgery (water tight anastomosis, nerve sparing, etc.) with the minimally invasive benefits (less blood loss, reduced length of stay) of laparoscopy. I would not have any surgery these days without first asking if there is a robotic approach.
