Intended Use

The Navigated Instrument System is indicated for use during the preparation and placement of Orthofix screws during spinal surgery to assist the surgeon in precisely locating anatomical structures in either open or minimally invasive procedures. The Navigated Instrument System reusable instruments are specifically designed for use with the Brainlab Vector Vision system and the Medtronic StealthStation System which are indicated for any medical condition in which the use of stereotactic surgery may be appropriate and where reference to a rigid anatomical structure such as a skull, a long bone, or vertebra can be identified relative to a CT or MR based model, fluoroscopy images, or digitized landmarks for the anatomy. Use of the Navigated Instrument System is limited to use only with the Firebird Spinal Fixation System / Phoenix MIS Spinal Fixation Systems.

Device Story

Navigated Instrument System consists of manual surgical instruments (bone awls, taps, probes, screw drivers) used with Brainlab VectorVision or Medtronic StealthStation navigation systems; instruments facilitate precise anatomical localization during spinal surgery; surgeon uses system to track instrument position relative to patient anatomy (CT/MR/fluoroscopy) in real-time; provides 3D/2D visualization for pedicle screw placement; used in OR by surgeons; output confirms hardware placement accuracy; benefits include improved precision in complex/MIS procedures.

Clinical Evidence

No clinical data. Bench testing only. Validation included dimensional measurements, geometric comparisons, and performance testing in a simulated surgical navigation environment to confirm compatibility with Medtronic StealthStation S7 and accuracy of the new instrument configurations.

Technological Characteristics

Manual surgical instruments (awls, taps, probes, screw drivers) designed for compatibility with optical navigation systems (Brainlab/Medtronic). Dimensions: Taps/screws 4.5mm-8.5mm diameter, 25mm-55mm length. Materials: Reusable surgical grade materials. Connectivity: Passive tracking via integration with external navigation system hardware (trackers/reference frames).

Indications for Use

Indicated for patients undergoing spinal surgery requiring preparation and placement of Orthofix screws (Firebird/Phoenix systems) where stereotactic navigation is appropriate; applicable for open or minimally invasive procedures requiring anatomical localization via CT, MR, or fluoroscopy.

Regulatory Classification

Identification

This surgical imaging technology provides surgeons visualization for complex and MIS procedures and confirms the accuracy of advanced surgical procedures. Use of these navigation systems provides the surgeon access to real-time, multi-plane 3D images (and 2D images) providing confirmation of hardware placement. Use of the Navigated Instrument System is limited to Taps ranging in sizes of 4.5mm to 8.5mm and bone screws ranging from 4.5mm to 8.5mm with length ranging from 25mm to 55mm. The Navigated Instrument System Medtronic and Brainlab compatible instruments are comprised of Bone Awl, Bone Taps, Bone Probes and a variety of Screw Drivers. The Navigated Instrument System instruments were tested for compatibility utilizing the Medtronic StealthStation S7 Orange, Violet, and Gray Navlock Tracker (Part Numbers 9734683, 9733482, 9734590 and 9732353), Medtronic Navigation Instrument Driver (Part Number 9734279) and the Navlock Reference Frame (Part Number 9732353) while utilizing the Navigated CD Horizon Solera Operative Technique with control number PMD016466-1.0 31441. ## Intended Use / Indications for Use The Navigated Instrument System is indicated for use during the preparation and placement of Orthofix screws during spinal surgery to assist the surgeon in precisely locating anatomical structures in either open or minimally invasive procedures. The Navigated Instrument System reusable instruments are specifically designed for use with the Brainlab Vector Vision system and the Medtronic StealthStation System which are indicated for any medical condition in which the use of stereotactic surgery may be appropriate and where reference to a rigid anatomical structure such as a skull, a long bone, or vertebra can be identified relative to a CT or MR based model, fluoroscopy images, or digitized landmarks for the anatomy. Use of the Navigated Instrument System is limited to use only with the Firebird Spinal Fixation System / Phoenix MIS Spinal Fixation Systems. # Summary of the Technological Characteristics of the Device Compared to the Selected Predicate Devices The technological characteristics of the subject Navigated Instrument System were compared to the predicate devices in indications for use, intended use, design, technology, materials, function and performance. It was demonstrated that the subject Navigated Instrument System technology is substantially equivalent to the predicate devices. # PERFORMANCE DATA – Summary of Non-Clinical Test Conducted for Determination of Substantial Equivalence Engineering analysis and performance data demonstrate that the subject Navigated Instruments are substantially equivalent to the predicate devices in compatibility, accuracy, function and performance. Engineering analysis includes dimensional measurements of both the predicate devices and subject devices and geometrical comparisons to currently marketed Orthofix Instruments. Validation testing includes physical testing with all Navigated Instrument System Screwdrivers to ensure compatibility with the system software and 1:1 accuracy and performance testing of the subject and predicate device in a simulated surgical navigation use environment. Therefore, it can be concluded that the compatibility, accuracy, function, and performance of the subject Navigated Instrument System are substantially equivalent to the predicate devices. {5}------------------------------------------------ Image /page/5/Picture/1 description: The image shows the word "ORTHOFIX" in bold, black letters.
