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?
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.
