Minimally Invasive Surgical Robot Benefits Surgeons and Patients

A novel robotic device increases the safety and reliability of various neurological and orthopedic procedures, without compromising established surgical protocols.

The ROSA robotic assistant is an integrated multi-application console that acts as a reliable and accurate surgical assistant. With six degrees of freedom, the robotic arm architecture can accurately replicate the movements of a human arm, providing high dexterity while completing complex surgical procedures, as well as allowing complete freedom in a choice of trajectories. Advanced haptic capabilities help the neurosurgeon to easily guide instruments by hand, while remaining within the limits and restrictions established during the planning stage.


The surgeon is able to easily interact with the robot without changing any of his surgical techniques, thus reaping the full benefits of robotic movement. A further advantage is a noninvasive and touch-free registration system that combines precise robotic movement with peripheral laser measurements to register patient volumes, without the use of invasive markers or a stereotactic frame. The ROSA Spine robotic assistant is a product of Medtech (Montpellier, France), and has been approved by the US Food and Drug Administration (FDA) for brain and spine procedures.

“In the coming years, hospital neurosurgery departments will face an influx of patients with increasing costs of care, whereas healthcare budgets are shrinking,” said Bertin Nahum, CEO, MedTech. “MedTech seeks to provide better care by facilitating minimally invasive procedures with our ROSA robots for brain and spine surgery.”

Robotics technology is making headway in practically every major surgical discipline, with the global demand particularly high for prostatectomy and hysterectomy procedures, as they are believed to offer greater safety, accuracy, and precision, thus leading to better clinical outcomes for the surgeon, patient and hospital management. Advanced imaging, higher degrees of freedom, intuitive interfaces, improved haptics feedback, and remote operation are being continuously developed to further strengthen the capabilities of surgeons.
