Sep 28,2025

In the field of dental diagnosis and treatment, the compliance of medical devices directly affects both patient safety and treatment outcomes. The Dental Root Canal Length Measurer (Model LY-A660), manufactured by Foshan Liangya Dental Equipment Co., Ltd., has earned the trust of oral healthcare institutions as a reliable diagnostic and therapeutic tool, thanks to its comprehensive certification system. This product is certified with a Medical Device Registration Certificate.

# Foshan Liangya - Dental Root Canal Length Measuring Device with All Three Certifications

## I. The Three-Certificate System Lays the Foundation for Healthcare Safety

The three-certification system not only demonstrates the company's strict adherence to medical regulations but also ensures that every piece of equipment meets the national Class II medical device management requirements by standardizing technical parameters, controlling production processes, and systematizing risk assessments. Take the core component of a root canal measuring device as an example—the probe’s precision error is kept within ±0.1mm, a figure rigorously verified and certified by the National Medical Products Administration. This level of accuracy directly impacts the precision of working length measurements during root canal treatment, helping to prevent risks such as over-preparation or instrument fracture caused by measurement inaccuracies.

## II. Multi-Frequency Localization Technology Overcomes Clinical Pain Points

Traditional root canal measurements rely on X-rays or tactile feedback, but they have limitations such as radiation exposure, image distortion, and time-consuming procedures.

This device visualizes the movement path of root canal files, enabling quick localization even when dealing with complex anatomical structures. More notably, its automatic calibration feature eliminates interference from variables such as tooth type and root canal morphology, allowing for standardized "plug-and-test" operation.

## III. Human-Centric Design Empowers Diagnostic and Treatment Efficiency

While ensuring measurement accuracy, the Liangya team integrates user experience into every stage of product development. The device features a foldable structural design, with the screen angle freely adjustable between 0 and 90 degrees to accommodate various dental chair positions. Additionally, accessories such as the file clamp and lip hooks are crafted from medical-grade stainless steel, which remains deformation-free and corrosion-resistant even after being sterilized under high temperature and pressure at 134°C.
