Intended Use
The GYDER® Hip Navigation System is a computer-controlled system intended to assist the surgeon in determining reference alignment axes in relation to anatomical structures during stereotactic orthopaedic surgical procedures. The GYDER® Hip Navigation System facilitates the accurate positioning of the acetabular cup only during Anterior Hip Arthroplasty approaches with the patients in supine position. The GYDER® Hip Navigation System is intended to be used only during Anterior Hip Arthroplasty approaches with the patients in supine position, with acetabular cups that are uncemented and allow for post-impaction measurement and confirmatory measurement.
Device Description
The GYDER® Hip System is a computer controlled non-invasive surgical tool to aid navigation during Total Hip Arthroplasty via the Anterior Approach. The system includes both reusable and consumable components, designed to work together to assist the surgeon in positioning the acetabular cup in the intended orientation during primary or revision Total Hip Arthroplasty.
More Information

No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the description focuses on computer-controlled navigation based on anatomical structures and reference alignment axes, which is typical of traditional surgical navigation systems. There is no mention of learning, training data, or complex pattern recognition that would indicate AI/ML.

No
The device is a computer-controlled system intended to assist the surgeon during hip replacement procedures by providing navigation and guidance for acetabular cup placement, which is a surgical tool, not a therapeutic device that directly treats a condition.

No

The device is described as a "computer-controlled non-invasive surgical tool to aid navigation during Total Hip Arthroplasty," which assists the surgeon in positioning the acetabular cup. Its purpose is to guide surgical actions, not to diagnose a condition or disease.

No

The device description explicitly states that the system includes both reusable and consumable components, indicating the presence of hardware in addition to software. The performance studies also mention "System hardware verification/validation."

Based on the provided information, the GYDER® Hip Navigation System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use clearly states that the system is "intended to assist the surgeon in determining reference alignment axes in relation to anatomical structures during stereotactic orthopaedic surgical procedures." This describes a surgical navigation tool used during a surgical procedure on a patient, not a test performed on a sample taken from a patient.
  • Device Description: The description calls it a "computer controlled non-invasive surgical tool to aid navigation during Total Hip Arthroplasty." This further reinforces its role as a surgical aid.
  • Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, tissue, etc.)
    • Detecting or measuring substances in biological samples
    • Providing information for diagnosis, monitoring, or screening of diseases or conditions based on analysis of biological samples.

The GYDER® Hip Navigation System is a surgical navigation system, which falls under the category of medical devices used to guide surgical procedures.
