Robotic-assisted surgery for cancer treatment

Surgery is an efficient treatment method, however, any surgical intervention (even the smallest of incisions) causes new damages to the body. Minimally invasive surgery aims to minimize those damages. Development of advanced technology and the use of robots in medicine constitute a turning point in surgery. Robotic-assisted surgery is a new step in minimally invasive surgery that provides significant advantages both to patients and surgeons.

What are the advantages of robotic surgery?

One of the greatest advantages of this method is that it allows for surgery in areas that are inaccessible through open surgery, laparoscopy or thoracoscopy. Robotic-assisted surgery allows for safer and more comfortable interventions as it provides a high-definition 3D view and an increased range of motion and dexterity in handling surgical instruments. The robot can show the surgeon formations that are invisible to the naked eye by displaying an up to 12-fold magnified view of the surgical site. Robotic arms can perform seven free movements and two major rotations. The system flirts with any hand tremor that exceeds 6 Hz. If the surgeon moves his hand by 5 cm, the tip of the robotic arm only moves by 1 cm. Compared with the natural human 180° range of motion, each of da Vinci’s arms has a 540° range of motion which enhances the maneuverability of the surgeon, thus enabling him to perform more sensitive and more complicated actions with the required precision.

How is the da Vinci robot used in surgical oncology?

The da Vinci Surgical System is usually preferred in surgical oncology and organ transplantation procedures. It is especially suitable for removal of tumor formations in hard-to-reach areas where intervention with hands or conventional instruments is impossible.

Aided by a high-definition 3D view and the greatly flexible robotic arms, the surgeon can easily reach any organ or lymph node that has to be removed and can perform the needed intervention without any damages to nerves, blood vessels or adjacent organs. Thus, the surgeon gains significant control both over the cancerous tissue that has to be removed and over the organs that have to remain intact. This technology brings about long-term results and comfortable life for patients. Besides, the procedure requires only a tiny incision accompanied with less blood loss and reduced pain, which results in shorter hospital stays. All that enables quicker recovery after surgery and faster return to normal life.

To perform successful da Vinci procedures, the surgeon has to possess special knowledge in anatomy and needs to be trained how to work with and get used to the system, because it is the expertise of the surgeon which matters the most.
