What is a Robotic Surgery?  


Robotic surgery is a method to perform surgery using very small tools attached to a robotic arm. The surgeon controls the robotic arm with a computer. Dr. Kolachalam would like his patients to be well informed about the decisions that they make regarding their overall health and the options for surgery. da Vinci® Single-Site® Surgery introduces several key features that allow Dr. Kolachalam to operate through one small opening or port.

  • Single-Site port: The port is the opening your surgeon creates in your body that allows him/her to remove your gallbladder. With da Vinci Single-Site, the port is in your belly button.

The animation video below will show you how da Vinci Single-Site works.



Features of da Vinci Surgery


The da Vinci Surgical System offers the latest in surgical and robotics technologies. The da Vinci System is beneficial for performing routine and complex surgery. Dr. Kolachalam is 100% in control of the da Vinci System, which translates his hand movements into smaller, more precise movements of tiny instruments inside your body.

The da Vinci Surgical System features a magnified 3D high-definition vision system coupled with flexible Single-Site instruments. These features enable Dr. Kolachalam to operate with enhanced vision and precision.

What is Minimally Invasive Surgery (MIS)?


MIS is surgery typically performed through small incisions, or operating ports, rather than large incisions, resulting in potentially shorter recovery times, fewer complications, reduced hospitalization costs and reduced trauma to the patient.

Why do we need a new way to do minimally invasive surgery?


Despite the widespread use of minimally invasive or laparoscopic surgery in today’s hospitals, adoption of laparoscopic techniques, for the most part, has been limited to a few routine procedures. This is due mostly to the limited capabilities of traditional laparoscopic technology, including standard video and rigid instruments, which surgeons must rely on to operate through small incisions.

In traditional open surgery, the physician makes a long incision and then widens it to access the anatomy. In traditional minimally invasive surgery – which is widely used for routine procedures — the surgeon operates using rigid, hand-operated instruments, which are passed through small incisions and views the anatomy on a standard video monitor.


What are the benefits of da Vinci Surgery compared with traditional methods of surgery?


Some of the major benefits experienced by surgeons using the da Vinci Surgical System over traditional approaches have been greater surgical precision, increased range of motion, improved dexterity, enhanced visualization and improved access. The surgical site heals quicker and with less pain with recovery. da Vinci Surgical System offers many potential benefits to patients facing surgery.

To learn more about the benefits of specific da Vinci procedures, go to Since surgery is unique to each patient and procedure, benefits cannot be guaranteed.


Where is the da Vinci Surgical System being used now?


Currently, The da Vinci Surgical System is being used in hundreds of locations worldwide, in major centers in the United States, Austria, Belgium, Canada, Denmark, France, Germany, Italy, India, Japan, the Netherlands, Romania, Saudi Arabia, Singapore, Sweden, Switzerland, United Kingdom, Australia and Turkey.


Has the da Vinci Surgical System been cleared by the FDA?


The U.S. Food and Drug Administration (FDA) has cleared the da Vinci Surgical System for a wide range of procedures. Please see the FDA Clearance page for specific clearances and representative uses.


Is da Vinci Surgery covered by insurance?


da Vinci Surgery is categorized as robot-assisted minimally invasive surgery, so any insurance that covers minimally invasive surgery generally covers da Vinci Surgery. This is true for widely held insurance plans like Medicare. It is important to note that your coverage will depend on your plan and benefits package.

For specifics regarding reimbursement for da Vinci Surgery, or if you have been denied coverage, please call the Reimbursement Hotline at 1-888-868-4647 ext. 3128. From outside the United States, please call 33-1-39-04-26-90.


Will the da Vinci Surgical System make the surgeon unnecessary?


On the contrary, the da Vinci System enables surgeons to be more precise, advancing their technique and enhancing their capability in performing complex minimally invasive surgery. The System replicates the surgeon’s movements in real time. It cannot be programmed, nor can it make decisions on its own to move in any way or perform any type of surgical maneuver without the surgeon’s input.


Is a surgeon using the da Vinci Surgical System operating in “virtual reality”?


Although seated at a console a few feet away from the patient, the surgeon views an actual image of the surgical field while operating in real-time, through tiny incisions, using miniaturized, wristed instruments. At no time does the surgeon see a virtual image or program/command the system to perform any maneuver on its own/outside of the surgeon’s direct, real-time control.


Is this telesurgery? Can you operate over long distances?


The da Vinci Surgical System can theoretically be used to operate over long distances. This capability, however, is not the primary focus of the company and thus is not available with the current da Vinci Surgical System.


While using the da Vinci Surgical System, can the surgeon feel anything inside the patient’s chest or abdomen?


The system relays some force feedback sensations from the operative field back to the surgeon throughout the procedure. This force feedback provides a substitute for tactile sensation and is augmented by the enhanced vision provided by the high-resolution 3D view.


What procedures have been performed using the da Vinci Surgical System? What additional procedures are possible?


The da Vinci System is a robotic surgical platform designed to enable complex procedures of all types to be performed through 1-2 cm incisions or operating “ports.” To date, approximately 1.5 million procedures including general, urologic, gynecologic, thoracoscopic, and thoracoscopically-assisted cardiotomy procedures have been performed using the da Vinci Surgical System.


Why is it called the da Vinci® Surgical System?


The product is called “da Vinci” in part because Leonardo da Vinci invented the first robot. He also used unparalleled anatomical accuracy and three-dimensional details to bring his masterpieces to life. The da Vinci Surgical System similarly provides physicians with such enhanced detail and precision that the System can simulate an open surgical environment while allowing operation through tiny incisions.


What are the risks associated with this type of surgery?


All surgery presents risk, including da Vinci® Surgery and other minimally invasive procedures. Serious complications may occur in any surgery, up to and including death. Examples of serious or life-threatening complications which may require hospitalization include injury to tissues or organs, bleeding, infection or internal scarring that can cause long-lasting dysfunction or pain. Temporary pain or nerve injury has been linked to the inverted position often used during abdominal and pelvic surgery. Risks of surgery also include potential for equipment failure and human error.

Risks specific to minimally invasive surgery may include: A long operation and time under anesthesia, conversion to another technique or the need for additional or larger incisions. If your surgeon needs to convert the procedure, it could mean a long operative time with additional time under anesthesia and increased complications. Temporary pain or discomfort may result from pneumoperitoneum, the presence of air or gas in the abdominal cavity used by surgeons in minimally invasive surgery. Research suggests that there could be an increased risk of incision-site hernia with single-incision surgery. Results, including cosmetic results, may vary. Patients who bleed easily, who have abnormal blood clotting, are pregnant or morbidly obese are typically not candidates for minimally invasive surgery, including da Vinci® Surgery. Other options may be available.

Patients should talk to Dr. Kolachalam about their surgical experience and to decide if da Vinci Surgery is right for them. We encourage patients to review all available information on surgical options and treatment in order to make an informed decision. Clinical studies are available through the National Library of Medicine at For more complete information on surgical risks, safety, and indications for use, please refer to
