Robotic Surgery Unit
Robotic surgery is an approach combining traditional minimally invasive surgery – laparoscopic, thoracoscopic or other – and the use of a robotic device.
How does Da Vinci Si HD robot work?
The Da Vinci system comprises three components: a surgical console, a body with robotic arms and a command tower with specific processors and a system of 3D high-resolution imaging.
Installed in the console, the surgeon performs the operation manipulating the controls that drive the robotic arms, guided by the three-dimensional imaging of the intervention area, with high-resolution and exhibited in his field of natural vision. The articulated and interactive robotic arms respond in real time to the commands of the surgeon, replicating with extreme accuracy the movements of his wrists, hands and fingers, but in the scale appropriate to the reduced dimension of the surgical instruments associated. The access of the surgical instruments to the operative field is made through small incisions in the body wall, called openings. However, while in conventional minimally invasive surgery the surgeon manipulates those instruments directly, in robotic surgery the robotic arms of the system body do it, always under the command of the surgeon at the console.
Such as in surgical interventions using other approaches, with Da Vinci Si HD robotic surgery system the patient is permanently under total control of the surgeon and his team. The interaction between the surgeon and his team is facilitated via a microphone at the console and a sound amplification system, and via monitors in the operating room transmitting the same image of the operative field that the surgeon sees at the console. During the operation, the surgeon’s assistant and the instrumentalist nurse remain close to the patient, assisting the surgeon in the choice and change of instruments and its connection to the robotic arms, or performing the necessary tasks.
The Da Vinci surgical system is highly safe. It integrates multiple safety systems, not being programmable nor making decisions on its own. Every manoeuvre requires the direct contribution of the surgeon and, during the operation, the system runs several safety checks. In the eventuality of power failure or problem in a safety check, the system allows the surgeon to keep total control of the intervention.
Which are the advantages of robotic surgery?
Generally speaking, robotic surgery presents as major advantages over open surgery all the benefits already known concerning minimally invasive surgery:
- Less post-operative pain
- Less overcharge and better response of the immunity system
- Faster general recovery
- Faster return to working activity
- Lesser incidence of infection
- Lesser incidence of incisional hernias
- Less visible surgical scars
Moreover, robotic surgery has technical features which increase the safety of procedures and potentiate the advantages of minimally invasive surgery for patients, namely:
- Higher-resolution and three-dimensional imaging
- The digital interface filters natural tremor and increases the precision of the surgeon’s movements
- The robotic arms rotate around a fixed point, reducing the traumatic tension and resulting in less post-surgical pain
- The relative position between the surgeon, the operative field and the surgical instruments (ergonomics – essential for the surgeon’s performance) is potentially perfect
- There is great freedom of movement of the instruments, which replicate the possible movements of the human wrist
- The dissection of tissues and the identification of natural anatomic plans is facilitated and made with higher-precision
- Manual sutures are more accurate and safe
In what areas is robotic surgery of use?
Robotic surgery has many areas of application, namely:
- In urologic surgery, especially in the treatment of prostate cancer
- In gastrointestinal surgery, especially in the treatment of rectal cancer
