Robotic Surgery
We can describe Robotic Surgery or robot-assisted surgery as performing certain operations through tiny holes using the “da Vinci” system. Robotic surgery provides numerous advantages to both patients and surgeons as it is the next step in minimal invasive surgery after laparoscopic surgery, which replaced conventional surgery.
With the help of instruments mimicking the movements of the wrist, intuitive motion control, high-resolution three dimensional images, it allows the surgeon to perform complex procedures using the laparoscopic method, transcending the limitations of conventional open surgery and laparoscopic surgery technologies. With this method, the surgeon sitting in the console can obtain a clear three-dimensional view of the operation site.

What does robotic surgery offer to a patient?
Reduced loss of blood 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.
Robot-assisted procedures result in shorter hospitalization as compared to open surgery. Patients recover faster and resume their everyday-life activities.
Less risk of infection.
The risk of infection is reduced in robotic surgery since 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 very 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 enable 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 robot 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.
A system 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. So procedures requiring high sensitivity can be easily carried out.
CyberKnife M6
Treatment technique, in which a very sensitive administration of high dose radiation into the stereotactically specified area is taking place while preserving other normal organs from acute and long-term toxic effects from radiation by causing a sudden drop in dosage outside targeted margins, is called stereotactic radiosurgery. Today, Cyberknife device is one of the most prominent devices to apply this technique.
Tumours in any region of the body can be easily treated with Cyberknife M6. Cyberknife M6 treatment is profoundly used in malignant or benign diseases localized in the brain, in tumours localized in the spine, head and neck, lung, pancreas, liver, adrenal and prostate glands. It is a rare device dedicated to stereotactic radiosurgery today with its presence ensuring patient comfort and easy applications compared to conventional systems.
Sensitive Robotic Structure
Cyberknife M6 uses a considerably sensitive robotic tech to treat tumours. It produces radiation for different sizes of areas in line with the shape of tumour with a linear accelerator placed on the robot. Robot can act in six different axes. For this reason, perfect dose distributions can be achieved by delivering radiation from many various angles with the help of the robotic arm in tumours localized particularly close to critical organs.
