Robotics in Neurosurgery

Dr Prem Pillay, Senior Neurosurgeon and Robotics in Neurosurgery Expert

Historical Origins

Robotics in neurosurgery represents a groundbreaking technological advancement that began in 1985, marking the first practical application of robotic systems in surgical procedures[1]. The Zeiss MKM Robotic Microscope and the Surgiscope in the early 2000-2010 period were also groundbreaking. The field has since evolved dramatically, driven by the need for increased precision, minimally invasive techniques, and enhanced surgical capabilities.

Types of Robotic Systems

Surgical Control Approaches

Neurosurgical robotic systems can be categorized into three primary control methods:

Surgeon Supervised Systems

– Preplanned surgical procedures

– Neurosurgeon plots robotic arm movements beforehand

– Robot performs predetermined movements

– NeuroSurgeon provides direct oversight[1]

Telesurgical Robots

– NeuroSurgeon controls surgical movements remotely

– Real-time control from a separate console

– Includes haptic feedback and live video transmission

– Enables surgery from outside the operating room[1]

Shared Control Systems

– Collaborative interaction between robot and Neurosurgeon

– NeuroSurgeon maintains primary movement control

– Robot provides stabilizing forces[1]

Notable Robotic Neurosurgery Platforms and Systems

Advanced Robotic Systems include:

– NeuroArm: First MRI-compatible neurosurgical robot (launched 2008)

– ROSA ONE Brain: Provides minimally invasive brain procedures

– Renaissance Robotic System: Offers high dexterity for deep brain procedures

– CyberKnife: Pioneering radiosurgery platform[1][2][3]

– NDR Spine Robotics for Discoplasty and other Spine procedures

Future Trends in Robotics in Neurosurgery

Neurosurgical robotics is expected to become increasingly sophisticated, with potential multi-robot systems collaborating during complex procedures. The future likely involves more nuanced, adaptive robotic platforms that can handle intricate neurological interventions[6]. Dr Prem Pillay believes that future neurosurgical teams will include humanoid robotic assistants ( AI embodied) working with human Neurosurgeons using smart tools to remove brain tumors and brain cancers; correct spinal problems, and using finer tools and devices to replace diseased, injured or missing parts of the nervous system (Brain and Spinal Cord).

Robotic neurosurgery represents a transformative technological frontier, balancing remarkable precision with ongoing technological challenges. As research continues, these systems promise to revolutionize neurological interventions, offering unprecedented surgical capabilities while maintaining critical human expertise.
