Orthopedic Implant Inspection and Measurement

The Perfect Solution for Orthopedic Implant Inspection

There are many reasons why the VisionGauge® Digital Optical Comparator is widely used by orthopedic implant manufacturers to inspect and measure medical implants and devices:

  • Automatically compare parts to their CAD data (no more overlays!)
  • With its patented CAD Auto-Align™ and CAD Auto-Pass/Fail™ tools, the system can inspect and measure parts completely automatically!
  • Demonstrated accuracy down to +/-0.0001″ in real-world applications, directly on the shop floor!
  • Eliminate operator subjectivity!
  • Much faster than traditional approaches.
  • Because the system doesn’t require any programming, it is especially well adapted for small lots & quick part changeover.
  • Automatically collect measurements, statistics, images and other data for complete documentation.
  • The system is not limited to the camera’s field-of-view; It can compare a part to its CAD data across the entire stage travel. So even large parts can be checked at high magnification, with very fine resolution.
  • With its extended optical depth-of-field and Auto-Focus tool, the system is perfectly suited to deal with the challenges of orthopedic implant inspection.
  • Different types of adapted computer-controlled LED illumination are available to eliminate glare and make defects stand out. The system works extremely well on both metal & plastic parts!
  • Automatically measure and display deviations from nominal and quickly identify out-of-tolerance areas.

Automatic Bone Screw Inspection and Measurement

VisionGauge® Digital Optical Comparators are the perfect solution for automatic bone screw inspection and measurement.

There are many reasons why the VisionGauge® Digital Optical Comparator is widely used by medical device manufacturers for automated  inspection and measurement of bone screws:

  • Automatically compare bone screws against their CAD data
  • With its proprietary CAD Auto-Align™ and CAD Auto-Pass/Fail™ tools (Patents Pending), the system can check screws completely automatically, regardless of their orientation!
  • Eliminate operator subjectivity!
  • Automatically collect measurements, statistics, images and other data for complete device history information
  • Thanks to the system’s extended depth-of-field, the entire screw can be in focus even at the helix angle (no need to constantly refocus)!
  • Measure the bone screw’s thread major and minor diameters and other characteristics, completely automatically and to a very high accuracy
  • With the optional rotary stage, you can automatically measure the helix angle, very accurately!
  • The system is perfect for bone screw inspection and measurement directly on the shop floor

For bone screws inspection and measurement on the VisionGauge® Digital Optical Comparator, some manufacturers use horizontal configurations, while others use a vertical configuration. The decision to use one or the other is generally based on fixturing considerations. The hard chrome plated stage, made from hardened tooling steel, has industry standard dual dovetail grooves that make it compatible with existing mounting fixtures, and a drop-in replacement for traditional optical comparators. Rotary stages are also an option that can be added to these systems.
