The root canal file extractor is a specialized minimally invasive tool for addressing instrument separation during root canal treatment, enabling precise removal of broken files while protecting the root canal structure. It adopts a modular design (consisting of an operating handle, adjustable clamping sleeve, and needle core). The clamping sleeve can be adjusted at multiple angles to fit curved root canals, and the handle is ergonomically designed for one-handed operation. It offers multiple specifications of needle cores compatible with broken #15-#40 files, with stable clamping force (8-12N) and resistance to high-temperature and high-pressure sterilization at 134°C. Some models are equipped with fiber optic illumination to enhance visibility.
The operation follows a four-step process: “canal preparation – angle adjustment – locking and clamping – minimally invasive removal”. When used with a microscope, the success rate of removal can exceed 85%, which shortens the operation time (15-25 minutes) and reduces the amount of dentin removed by 40%. Additionally, it is reusable for over 50 times, balancing treatment efficiency, tissue protection, and cost-effectiveness. It is suitable for various scenarios involving broken instruments in root canals.
