Robotic Surgery

Robotic surgery provides numerous advantages to both patients and surgeons. It is the next step in minimal invasive surgery after laparoscopic surgery, which replaced conventional surgery in several fields.

What robotic surgery offers to a patient?

  • Reduced blood loss and need for blood transfusion. Robotic surgical procedures are associated with less blood loss, particularly in cancer surgery. Consequently, this reduces the need for intraoperative or postoperative blood transfusion.
  • Less pain, less painkillers. As robotic surgery eliminates the need for large incisions, patients have less postoperative pain, and thus require fewer painkillers.
  • Shorter hospitalization. Robotic-assisted procedures result in shorter hospitalization as compared to open surgery. In several procedures, the patients are discharged on the same day of or the day after the intervention. Patients recover faster and resume their everyday-life activities.
  • Less risk of infection. The risk of infection is reduced in robotic surgery since, unlike open surgery, incisions are small and there is less bleeding.
  • Improved cosmetic outcome. Robotic surgery does not require any large incisions in the abdominal wall, and all interventions are carried out through 3 or 4 tiny holes in the abdomen. Thus, scarring is pretty insignificant.

High-resolution 3-D image

While standard laparoscopic images are obtained by a single camera, robotic surgery employs two high-definition cameras during the surgery, providing a three dimensional image with a 10x/12x magnification. The robotic instruments reach places in the body that are normally unreachable by the surgeon’s hand, and enables the surgeon to see structures which are too small to be seen by the naked eye. Thus the surgeon can operate in areas of abdominal or other body cavities, which otherwise cannot be reached in open surgery.

Better range of motion

The state-of-the-art robot in the Anadolu Medical Center has four robotic arms. One controls the camera and the other three hold surgical instruments. The two arms represent the right and left hands of the surgeon. The other arm allows additional tasks such as separating and retracting the tissue, and tracking surgical suturing. The robot is equipped with an articulate EndoWrist instrument. This device allows seven degrees of freedom and two degrees of axial rotation, mimicking three movements of the arm, three movements of the wrist for grasping or cutting. These instruments of greater range of motion and dexterity eliminate many challenges encountered during the two-dimensional laparoscopic surgery procedures.

Filtering hand tremors

The hand movements of the surgeon are scaled and translated to the robotic arms through a computer system. Even minor tremors of the hands are eliminated by this robotic technology. The system filters out hand tremors which are greater than 6 Hz so that procedures requiring high sensitivity can be easily carried out.
