How do lasers and ultrasonic devices expand the capabilities of robotic surgery?

In the field of robotic surgery, the integration of fiberoptically delivered lasers and ultrasonic vibratory devices significantly expands surgical capabilities by enabling more sophisticated interactions with human tissue.1

These energy sources are coupled directly to robotic systems to provide the following advantages:

• Tissue Interaction: They allow for precise interaction with multiple types of biological tissue, facilitating both the selective destruction of targeted areas and the careful preservation of surrounding healthy structures.1
• Enhanced Precision: By utilizing these devices, robotic systems can perform tasks that require high levels of control, such as cutting or ablating tissue, with greater accuracy than traditional manual methods.1
• Versatility: The use of these energy sources supports the broader goal of minimally invasive surgery, allowing surgeons to operate in areas where visualization and access have traditionally been difficult.1

While lasers are often used for their ability to cauterize and cut through tissue via absorbed energy, ultrasonic devices leverage high-intensity vibrations to interact with materials. Together, these technologies help robotic platforms achieve greater dexterity and precision, ultimately aiming to reduce patient stress and improve surgical outcomes.231
