Robotic Surgery System Guides Needle-Based Procedures

A hands-free robotic surgery system uses image-based planning tools and navigation systems to insert and steer various instruments to a desired location within the body.

The XACT Robotics (Caesarea, Israel) is a novel, patient-mounted, five degrees-of-freedom robot designed to facilitate predictable delivery of needles and various other instruments to a desired target within an accuracy range of within 1.5 millimeters, with concomitant planning of the proposed needle path. Once the desired target and the proposed trajectory are confirmed, the XACT technology assures hands-free insertion and steering, while at the same time compensating for any instrument deviation. In addition, the needle path can be adjusted without reinserting it or repositioning the patient.


The technology also compensates for breathing and patient movement intraoperatively, contributing to a predictable and safe performance that minimizes procedure duration. Additional features include a small footprint, high mobility, and ease of use, which enable care providers to treat a broad range of patient care needs in various clinical sites of service. XACT technology is designed to be compatible with a broad range of imaging modalities, including computerized tomography (CT)-guided percutaneous interventions, tissue biopsies, abscess drainage, or ablations.

“We are committed to redefining the way the entire medical community utilizes robotics, beginning with interventional radiologists,” said Harel Gadot, founder, executive chairman, and president of XACT Robotics. “Being the first to introduce a hands-free robotic system, we have the potential to provide significant clinical, technical and economic value while democratizing interventional procedures. Our system’s small footprint and high mobility design will enable care providers to treat a broad range of patient care needs in various clinical sites of service.”

“The XACT Robotic System provides a unique platform to the interventional radiology community which can help improve the delivery and quality of care for the patients we serve,” said Professor Nahum Goldberg, MD, director of the Applied Radiology Research Lab at Hadassah Hebrew University Medical Center (Jerusalem, Israel). “Based on our experience with this unique robotic technology, we can reach very small targets with unprecedented accuracy. Furthermore, this system holds much promise for enabling more efficient use of time and hospital resources.”
