Da Vinci Xi Surgical System

An ideal assistant in prostate cancer surgery


The Da Vinci Xi robotic surgical assistant features flexible robotic arms designed to move and rotate in 7 directions. Acting like the surgeon’s extra arm, the system provides high-definition 3D views through a small opening of internal organs including the prostate gland, located in a hard-to-reach area behind the pelvic bones. The images can be magnified up to 10 times their actual size. The system’s efficiency and precision makes it ideal for procedures that are complex or involve difficult-to-reach areas of the body.


The Da Vinci Xi’s characteristics make it suitable for complex prostate surgery, where the operative field is difficult to reach, as well as for patients with high BMI and body weight. With its robotic arms and working mechanisms, it enables surgeons to make incisions that are smaller than traditional open surgery incision. This helps minimize the risk of nerve trauma during surgery, which can lead to erectile dysfunction, and reduces blood loss and recovery time.

  • Miniature robotic arms designed to move and rotate in any direction enables surgeons to separate the prostate gland from the surrounding nerves, preventing nerve trauma and minimizing sexual dysfunction following surgery.
  • Robotic assistance during minimally invasive surgery (MIS) results in less operative time, smaller incisions, less pain and fewer complications after surgery.
  • One of the robotic arms functions as a miniature camera capable of delivering high-definition 3D images and magnifying them by up to 10 times. This allows the surgeon to completely remove the malignant tumor while preserving the sexual nerves surrounding the prostate gland.



  • Suitable for complex surgical procedures in difficult-to-reach areas of the body e.g. prostate cancer, colorectal cancer, gallbladder and hernia surgeries.
  • Suitable for minor surgery. The minimal incisions lead to faster recovery time and little abdominal scarring, even in surgery to remove uterine or ovarian tumor.
  • Suitable for overweight and metabolic patients seeking minimally invasive gastric (bypass) surgery (bariatric surgery?]

The Da Vinci Xi Surgical System features flexible robotic arms that can rotate and pivot in 7 directions. One arm is equipped with a tiny camera that provides surgeons with high-definition 3D views of the surgical area at 10 times magnification of what the naked eye can see. Its high precision makes the system suitable for prostate surgery, a complex procedure due to fact that the prostate gland is located in a narrow, hard-to-reach space under the pelvic bones. With the Da Vinci Xi, surgeons can separate the prostate gland from the surrounding sexual nerves, preventing nerve damage and minimizing sexual dysfunction problems following surgery.


Acting as a surgical assistant, the Da Vinci Xi replicates the hand movements of your surgeon, who is seated at the console in front of a 3D screen. The system features 4 robotic arms. The first arm functions as a camera, capturing and sending images to the screen, to provide the surgeon with high-definition 3D views of the surgical area including details such as tissue and nerves. The other arms serve as wrist instruments that can rotate and bend up to 120 degrees in 7 directions, which is more than a human hand can achieve.


The Da Vinci Xi’s robotic arms and operating mechanisms effectively facilitate surgical procedures in complex or difficult to reach areas of the body, as well as in patients with high BMI and body weight. These procedures include organ surgery, tumor and cancer surgery, gastric bypass (bariatric?) surgery and medical implants of devices such as a surgical mesh for hernia repair. In every type of procedure, using the Da Vinci Xi results in incisions that are much smaller than the traditional open incision, reducing blood loss and ensuring a smooth operation and faster recovery time for patients.


Thonburi Hospital is one of the first hospitals in Thailand to adopt the 4th generation Da Vinci technology to assist surgeons in complex surgery. Compared to previous-generation models, the more advanced Da Vinci Xi allows surgeons to simultaneously perform an incision and close it (and close another?) using skin staples. It also helps minimize complications after surgery.


However, robotic surgery may not be suitable for every patient. Your doctor will assess its suitability for your case and explain the potential risks and complications that you might face.
