Medical Devices

The medical device industry covers a wide variety of products used in the treatment of patients, including dental equipment, diagnostic devices, cardiovascular devices, surgical equipment, medical equipment, ophthalmic devices, orthopaedic devices and respiratory devices.

The manufacturers of medical devices must ensure their products comply with standards intended to maximize patient safety. Quality control is an essential part of the manufacturing process to ensure the highest quality standards.

Accurate inspection of medical devices

Stent medical device

Most inspection conducted for quality purposes require components to be thoroughly examined for surface imperfections such as burrs and dust debris.

For medical device components 100% inspection is necessary, making sure every product is sent out meeting every aspect of product specifications.

Vision Engineering’s Lynx zoom stereo microscope and Mantis stereo microscope are used around the world for the accurate inspection of medical devices.

From the inspection of stents, to needles, catheters and ophthalmology instrumentation, the stereo microscopes designed and manufactured by Vision Engineering offer superior optics inspecting critical components. They show high contrast images needed to spot small imperfections on and below the surface of samples.

One of the key selling points of the Mantis Elite microscope is the large working distances which allow operators to rework the items quickly and easily without further adjustments.

For example, burrs might require removal which can easily be achieved with the Mantis Elite and its quick change turret, holding both a lower magnification objective lens and a higher objective lens, simultaneously. This will enable operators to instantaneously switch between magnification during inspection and rework with minimum effort.

Critical dimensional measurement of medical devices

Dimensional accuracy of components for medical devices is crucial ensuring every part fits the tight tolerances often associated with medical device components, whether they are manufactured from plastics, rubber, or metals.

Using probes for dimensional accuracy often risks the component becoming deformed, especially if it is an intricate size with complex fine features.

To eradicate this variable and yet enabling consistent, repeatable measurement, the Vision Engineering range of non-contact measurement systems offer accurate reproducibility in X, Y and Z.

Used around the world by leading manufacturers of medical devices, the systems offer the versatility of configuration tailored to specific needs. For example, common requirements include a combination of optics and/or video; manual and/or automated measurement; macro or micro magnification ranges.
