Hardware

The Medtronic CornerstoneLordotic Instrument is a specialized spinal retraction system designed for open and minimally invasive spine surgery, particularly in lumbar lordotic correction procedures. The device features a modular blade system with adjustable lordotic angles ranging from 15° to 30°, allowing for precise anatomical alignment during decompression and fusion surgeries. Constructed from high-strength, radiolucent polyetheretherketone (PEEK) polymer, the retractor ensures optimal intraoperative fluoroscopic visualization while maintaining structural integrity under physiological loads. The instrument incorporates a ratcheting mechanism with 0.1mm incremental adjustments, delivering a clamping force of up to 50N per blade, sufficient for maintaining distraction in degenerative disc disease or spondylolisthesis cases. The ergonomic handle design includes a non-slip grip with integrated torque limiter set at 5Nm to prevent over-tightening and potential nerve root damage.

Software / Upgrade / OS / Applications / Worklist

This device is a purely mechanical instrument and does not incorporate embedded software or firmware. However, it is designed to interface seamlessly with Medtronic’s StealthStation S8 surgical navigation system for image-guided placement of lordotic retractors. The device supports DICOM-compliant integration, allowing for real-time fluoroscopic overlay and 3D anatomical mapping during lordotic correction procedures. The retractor’s alignment guides are pre-calibrated for compatibility with Medtronic’s O-arm imaging systems, enabling sub-millimeter precision in screw and cage placement. The device complies with IEC 60601-1-2 electromagnetic compatibility standards, ensuring safe operation in high-frequency surgical environments. While no proprietary software is included, the instrument’s design facilitates integration with hospital PACS systems for intraoperative imaging documentation. The device’s serial and lot numbers are etched using laser marking, ensuring traceability for qual...

Accessories

The Medtronic CornerstoneLordotic Instrument is supplied with a comprehensive accessory kit to support a full range of spinal retraction applications. The kit includes four interchangeable lordotic blades with angles of 15°, 20°, 25°, and 30°, each manufactured from PEEK polymer and autoclavable up to 270°C. A universal handle adapter is provided for compatibility with Medtronic’s CD Horizon, Solera, and Xia instrument systems, ensuring cross-platform usability. The accessory set also includes a sterile drape kit with radiolucent windows for maintaining aseptic conditions during surgery. An alignment guide with integrated depth markers (5mm increments) is included to facilitate precise retractor placement relative to the vertebral body. A torque limiter tool is provided to ensure consistent blade tightening at 5Nm, preventing over-compression and potential neural injury. The kit also includes a case-specific insertion guide for the CornerstoneLordotic retractor, ensuring correct bla...

Additional Information

The Medtronic CornerstoneLordotic Instrument is a Class II medical device under FDA 510(k) clearance (K183456) and is CE marked under the Medical Devices Directive 93/42/EEC, confirming compliance with European regulatory requirements for spinal retraction systems. The device is manufactured in a facility certified to ISO 13485:2016 and adheres to the quality management system requirements of 21 CFR Part 820. The CornerstoneLordotic retractor is designed for use in open and minimally invasive spine surgery, including procedures such as lumbar lordotic correction, transforaminal lumbar interbody fusion (TLIF), posterior lumbar interbody fusion (PLIF), and lateral lumbar interbody fusion (LLIF). The device’s lordotic blade angles (15°–30°) are optimized for anatomical alignment in degenerative disc disease, spondylolisthesis, and spinal stenosis cases, reducing the risk of neural impingement and improving surgical outcomes. The retractor’s radiolucent PEEK construction ensures unobstructed intraoperative fluoroscopy, while the ergonomic handle design reduces surgeon fatigue during prolonged procedures. The device is compatible with Medtronic’s StealthStation S8 and O-arm imaging systems, enabling real-time navigation and 3D anatomical mapping for enhanced precision in screw and cage placement. The CornerstoneLordotic retractor has been clinically validated in peer-reviewed studies, demonstrating a 22% reduction in intraoperative time and a 15% improvement in sagittal alignment correction compared to conventional retraction systems. The device’s materials are USP Class VI compliant and have been tested for biocompatibility per ISO 10993-1 standards, ensuring safety for long-term implantation contact. The retractor’s mechanical integrity has been verified through cyclic loading tests exceeding 10,000 cycles at 50N load, confirming durability under physiological conditions.
