Mazor Robotics Introduces Renaissance C-OnSite Application for 3D Intra-Operative Implant Verification

Renaissance's C-OnSite application reduces potential for revision cases due to misplaced pedicle screws, while eliminating the need to purchase dedicated intra-operative 3D imaging systems

CAESAREA, Israel, May 23, 2012 (BUSINESS WIRE) -- Mazor Robotics Ltd (tase:MZOR), the leader in innovative surgical robots and complementary products for spine surgery, announced the global launch of the C-OnSite(TM) enhancement to its Renaissance(TM) system. Renaissance is Mazor Robotics' surgical guidance system for spine procedures and the incorporation of C-OnSite creates a full solution from planning, through surgical execution to verification. C-OnSite is a significant advance that enables fast, low-radiation, intra-operative 3D verification of implant placement, based on imagery from any standard 2D C-Arm which is available in almost every operating room. So it provides the clinical advantages of an intra-operative 3D imaging system but without the high radiation and capital costs.

"C-OnSite is a quantum leap forward for spine surgeons and their patients," said Dr. Neville Alleyne, orthopaedic spine surgeon at the Orthopaedic and Spine Institute at TriCity Medical Center in Oceanside, CA.

"The patient gets the equivalent of a post-op CT before leaving the operating room without the high radiation levels, and does not have to wait to rule out the need for revision surgery," said Dr. Payam Moazzaz, orthopaedic spine surgeon also at TriCity Medical Center.

Currently, the most common way to accurately verify the placement of pedicle screws is by post-operative CT. But it occurs after the surgery has been completed, so significant misplacements necessitate a revision surgery. Intra-operative imaging systems are usually 2 dimensional, which is not sensitive enough for verification purposes, and 3D systems are not common and are very expensive.

C-OnSite utilizes imagery from existing 2D C-Arms, which are standard equipment in spine operating rooms. A 15 second C-Arm scan is performed after screw positioning, and these images are fused with high-quality images from the preoperative CT. This produces an intra-operative 3D axial view of the spine, showing the exact location of each pedicle screw and its relationship to the spinal canal, without additional, expensive intra-operative 3D systems for spine surgery. So if a repositioning is necessary it can be done immediately, rather than as a revision case a few days later. The process requires no more than five to 10 minutes of additional OR time.

"Renaissance C-OnSite combines the enhanced accuracy of robotic guidance with actionable, intra-operative 3D image-based verification of screw positioning for immediate evaluation and correction," said Ori Hadomi, CEO of Mazor Robotics. "This offers the potential to reduce revision cases due to the misplacement of pedicle screws. By delivering post-op information during the surgical procedure, C-OnSite makes Renaissance a full solution for the spine surgeon, from pre-op planning through surgical guidance to verification. We expect the integration of C-OnSite with Renaissance will increase the overall clinical value of robotic guidance."

All Renaissance systems sold after May 28, 2012 will include the C-OnSite application.

Mazor will display C-OnSite in its booth # 213 at SpineWeek, which begins on May 28, 2012, in Amsterdam, and on May 31 at a satellite symposium for clinicians during the conference. For more information on Mazor's SpineWeek satellite symposium, please contact

C-OnSite is CE Marked and cleared by the U.S. Food and Drug Administration (under the former name of InCT).

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
