The Ideal Solution for Orthopedic Implant Inspection

Performing orthopedic implant inspection presents several challenges. This is due to the wide variety of implant sizes and shapes, plus the complex geometries that require tight tolerances. A 100% pass on inspection is an absolute necessity for proper quality assurance. Even a single defect in a medical implant can lead to catastrophic effects on a patient’s quality of life.

It is common for implants to be manufactured in small lots, leading to very high product changeover. Therefore, it helps if you can do precise medical implant inspection directly on the production floor.

And if the quality inspection system requires any programming, it needs to be as fast, easy, and error-free as possible. However, traditional inspection methods lack the advancements necessary to ensure speed and accuracy. Instead, they involve lengthy manual inspections.

The VisionGauge® Digital Optical Comparator is the solution to improving your quality management system and production process. Our comparators were originally developed in extensive collaboration with large medical OEMs to meet the requirements of orthopedic implant inspection and measurement. They are one of our system’s most ideal applications.

What Our Digital Optical Comparators Can Do

Our digital optical comparators are accurate, fast, and require minimal to no programming. The system can operate directly on the shop floor and produce automated inspection reports for documentation and approval. Our patented system software gathers complete device history and outputs all data from an inspection to a centralized database. The inspection data it collects include:

  • Part images
  • Pass/Fail results
  • Measurements
  • Statistics with graphs and charts

Our comparators also come with unique, patented tools, like our CAD Auto-Pass/Fail™ software. This innovative software efficiently and automatically compares a part directly to its CAD file with incredibly high dimensional accuracy, reducing operator variation and subjectivity.

Uses & Applications of Our Comparators

The VisionGauge® Digital Optical Comparator systems are successful on a broad range of orthopedic applications, such as stents, surgical instruments, and automated bone screw measurement and inspections.

Our systems have no limitations when it comes to part geometry, supporting a wide range of implants and parts, as well as a variety of implant materials. This makes VisionGauge’s Digital Optical Comparator a great choice for metal or plastic medical implant inspections.

Altogether, our systems are designed to make all aspects of the medical implant manufacturing process faster and easier. They’re also intended to ensure better outcomes in orthopedic implant testing and application for patients. Our comparators are great for inspecting and measuring medical implants for all areas of the human body, such as:

  • Dental Implants, such as custom-made abutments
  • Spinal Implants, like plates and rods
  • Hip Implants, such as hip prostheses
  • Knee Implants, such as fixed bearings or medial pivots
  • Orthopedic implants, like medical intramedullary nails (IM Nails)

Benefits of VisionGauge® for Orthopedic & Medical Implant Measurement

There are many reasons why VisionGauge® Digital Optical Comparators are employed by orthopedic implant manufacturers. Customers use them to inspect and measure the medical implants and devices they produce, benefitting from:

  • Automated CAD-to-Part Comparison: VisionGauge®’s patented CAD Auto-Align™ and CAD Auto-Pass/Fail™ tools are easy to use. They automatically inspect and measure parts, enabling high-accuracy results and ensuring top-notch quality standards.
  • High Accuracy & Consistency: Accuracy down to +/-0.0001″ demonstrated in real-world applications, directly from the shop floor! Our comparators make 100% consistent inspections between users, with no variation from operator to operator.
  • Improved Efficiency & Throughput: VisionGauge® Digital Optical Comparators are proven to be faster and allow for significant gains in throughput compared to traditional optical comparators or other inspection methods.
  • Digital Data Management: Automated programs can be stored and recalled per part as needed, or the system can be used in manual mode. Either way, the system is especially well-suited for inspecting small lots with rapid part changeover.
  • Specialized Tools: The systems provide multiple options for complete documentation and reporting of statistics, measurements, images, and other data. The system’s extended optical depth-of-field and Auto-Focus tool easily overcome the difficulties of orthopedic parts inspection.
  • Enhanced Image Clarity: Make defects stand out clearly and eliminate glare entirely with multiple options for adapted computer-controlled LED illumination. Automatically measure and display deviations in implant components to quickly and easily locate areas out of tolerance, both for metal and plastic parts.
