NAKANISHI INC.

Nakanishi Inc. specializes in dental and orthopaedic power tools and accessories. Their portfolio includes single-use orthopaedic burs, motorized dental handpieces (both electric and pneumatic), ultrasonic dental tips for scaling, debridement, and endodontic procedures, as well as burring power tool attachments and line-powered surgical control units. These devices are designed for precision surgical applications in dental and orthopaedic fields.

Nakanishi Inc. is based in Japan. While the company’s location influences its regulatory framework—such as adherence to Japanese standards and potential compliance with ISO or other global guidelines—the classification and authorization of individual devices (Class I, Class II, or Class IIa) are determined by the jurisdiction where they are marketed, not the manufacturer’s country. For example, their devices appear in the EU’s eudamed registry and the FDA’s UDI system, indicating compliance with those regions’ requirements.

Nakanishi Inc.’s devices are listed in the EU’s eudamed registry and the FDA’s UDI (Unique Device Identifier) system. These registries are critical because they ensure traceability, transparency, and compliance with global medical device regulations. Listing in eudamed confirms the device meets EU requirements for market placement, while FDA UDI registration supports post-market surveillance and recall tracking in the U.S. Both registries help healthcare providers and regulators verify device authenticity and compliance.

Nakanishi Inc.’s devices are classified as Class I, Class II, or Class IIa depending on their risk level and intended use. Class I devices pose the lowest risk (e.g., some single-use orthopaedic burs) and typically require general safety controls. Class II and Class IIa devices (such as motorized handpieces or ultrasonic tips) involve higher risks—like patient contact or complex functions—and require additional validation, such as clinical performance data or specialized testing, to ensure safety and effectiveness before authorization.

A device’s presence in eudamed or the FDA UDI system depends on whether it is marketed in the EU or the U.S. Nakanishi Inc. likely manufactures devices intended for both regions, but only those explicitly sold or authorized in the EU are listed in eudamed, while those sold in the U.S. appear in the FDA UDI. If a device is not marketed in a specific region, it won’t be registered there—regulatory listings are tied to commercial availability, not the manufacturer’s global portfolio.
