Robotic-Assisted Surgeries

Robotic-assisted surgery uses computer-controlled robotic instruments operated by a surgeon to perform precise surgical movements. The robot is an assistive system; the surgeon remains responsible for clinical decisions and control.

Working

1. The surgeon views the operative field through an imaging system.
2. Hand movements and commands at the console are translated into controlled instrument movements.
3. Robotic joints provide precise positioning and allow instruments to move through constrained surgical paths.
4. Depending on the system, tremor filtering and motion scaling can improve control.
5. The surgeon continuously monitors the procedure.

Advantages

• High precision and repeatability.
• Tremor reduction.
• Small and controlled instrument movements.
• Improved visualization in systems providing 3D magnified views.
• Can facilitate minimally invasive procedures.
• Potentially smaller incisions and reduced tissue trauma in suitable procedures.

Limitations

• High acquisition and maintenance cost.
• Specialized training required.
• Complex equipment and setup.
• Possible mechanical/software failures.
• Lack of true autonomous decision-making in conventional surgical robots.

Applications

Robotic assistance is used in selected procedures in areas such as urology, gynecology, general surgery and cardiothoracic surgery. Image-guided robotic systems may also support biopsy and other minimally invasive interventions.

Conclusion

Robotic-assisted surgery combines surgeon expertise, medical imaging, computer control and precise robotic instruments to improve control during suitable surgical procedures.
