The summary describes an optical navigation system that provides real-time measurements based on tracking spheres and a camera. There is no mention of AI, ML, or any related concepts in the device description, intended use, or performance studies. The system appears to rely on traditional computer vision and geometric calculations for navigation.
No.
The device is a navigation system that provides intra-operative measurements to aid in the selection and positioning of orthopedic implant components, rather than directly treating a condition or restoring function.
No
The device is an imageless optical navigation system intended to provide intra-operative measurements to a surgeon to aid in the selection and positioning of orthopedic implant system components during orthopedic surgery. It is not used for diagnosing medical conditions.
No
The device description explicitly states that the system consists of hardware components including an infrared Camera, Camera Drape, optical tracking Spheres, a computer Workstation, and associated hardware, in addition to software.
Based on the provided information, the Intellijoint® Navigation System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states that the system is for providing intra-operative measurements to a surgeon to aid in the selection and positioning of orthopedic implant system components during surgery. This is a surgical navigation and guidance system, not a device used to examine specimens derived from the human body for the purpose of providing information for diagnosis, monitoring, or compatibility testing.
- Device Description: The description details an optical navigation system with a camera, tracking spheres, and a computer workstation. This aligns with surgical navigation technology, not IVD technology which typically involves reagents, analyzers, or test kits for analyzing biological samples.
- Anatomical Site: The system is used directly on the patient's anatomy (pelvis, femur, tibia) during surgery. IVD devices analyze samples from the body, not the body itself.
- Performance Studies: The performance studies focus on benchtop accuracy, tracking system accuracy, software functionality, mechanical instrumentation, and simulated use on anatomical phantoms and cadavers. These are typical performance evaluations for surgical devices, not IVD devices which would involve studies on clinical samples and metrics like sensitivity, specificity, and accuracy in detecting or measuring analytes.
In summary, the Intellijoint® Navigation System is a surgical navigation system used to assist surgeons during orthopedic procedures. It does not perform in vitro diagnostic testing on biological samples.
N/A
Intended Use / Indications for Use
The Intellijoint® Navigation System is a computer-controlled, optical localizer intended to provide intra-operative measurements to a surgeon to aid in selection and positioning of orthopedic implant system components, where a reference to a rigid anatomical structure can be identified. The Intellijoint Navigation System is indicated for patients undergoing orthopedic surgery, and where the use of stereotactic surgery is considered safe and effective.
Intellijoint HIP aids the surgeon in performing intra-operative measurements of limb position, joint center-of-rotation, and implant component positioning.
