Taking the Pain out of Spinal Implants
Cervical Spinal Implant Part to CAD & Assembly Analysis
Many factors require consideration when developing products designed for use in internal medicine. From stringent quality guidelines to known product recalls, complications arise. Manufacturers of spinal implants face several issues regarding product design, material selection, and manufacturing processes. This is particularly important in cervical implants due to the heat that can be produced when using metal parts during MRIs. Furthermore, as a result of biocompatibility and corrosion issues with metal, the industry has seen a trend towards plastic alternatives.
Reducing a Pain in the Neck: Utilizing Part to CAD FASTScan Overlays and Assembly Analysis to Advance Spinal Implants
The industry: Medical Devices/Healthcare
The Client Issue:
In order to meet competitive demands and continue leading in a business-critical segment of the industry, our client needed to develop improved products from a material that was foreign to their process. They needed to transition to this new material while still upholding strict quality requirements and ensuring product safety.
The improvement to the product not only required a change in material but in the manufacturing process of the component. Performance requirements, coupled with the novelty of the situation, found the client in need of a non-destructive test method that could identify problems with shrinkage in addition to micro fractures resulting from overstress and compression. They were also interested in surface characteristics of the device, which would increase acceptance of the part once in the patient.
The 3DProScan Resolution:
With these considerations in mind, 3DProScan was able to offer our Part-to-CAD and Assembly Analysis services to respond to our client’s concerns. The results of both analysis services clearly illustrated further areas of improvement, allowing the client to hone in on specific areas of their process that needed to be addressed before product testing and subsequent launch.
The 3DProScan Difference:
- Process: After receiving the CAD file and importing the data, the physical component was scanned using Industrial Computed Tomography CT and a 3D dataset of the implant was created.
- Procedure: The nominal CAD model of the implant and the 3D dataset are then overlaid in order to provide a visual comparison of the two. Using our software, we are able to highlight areas where unintended shrinkage is occurring for the Part- to- CAD analysis. Assembly Analysis allows us to examine the piece for micro fractures and get an up close look at the surface features of the device.
- Advantage: 3DProScan was able to obtain clear visuals of the areas of concern as well as detailed images of important surface topography within hours of scanning the part.
When working with new materials or processes, 3DProScan’s industrial CT scanning technology is an outstanding way to evaluate your results quickly and accurately. Any low-density piece that fits in a 5”x5” cylinder can be scanned. We rapidly provide you with data at micron- level accuracy on critical regions and dimensions to aid in the advancement of your product.
