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.
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:
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.
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:
