Woodpecker Ai Motor (Yoshi) – by Dr. Yoshi Terauchi

The Woodpecker Ai Motor, developed in collaboration with world-renowned endodontist Dr. Yoshi Terauchi, represents a significant advancement in endodontic technology. This cordless, brushless endo motor integrates a high-precision apex locator, offering a complete 2-in-1 solution for root canal preparation and working length measurement. Designed for dental professionals who demand accuracy, safety, and efficiency, this smart endodontic motor enhances clinical outcomes while reducing procedural complexity.

The standout feature of the Woodpecker Ai Motor is the proprietary T-mode, specifically engineered for safely bypassing ledges and navigating challenging canal anatomy . Unlike conventional reciprocating motions, T-mode employs a watch-winding motion with a 90-degree clockwise and counterclockwise oscillation, allowing a pre-curved file to gently progress past obstructions. Once the ledge is bypassed, a single button press transitions the device into the programmed rotational mode for continued instrumentation . The motor delivers an expanded speed range of 100 to 2500 RPM and torque from 0.4 to 5.0 Ncm, making it suitable for both routine endodontics and complex retreatments .

The integrated apex locator provides real-time file tip position visualization on the high-resolution OLED display. Safety features include auto-start/stop when the file enters or exits the canal, auto-slowdown as the file approaches the narrow apex, and auto-reverse/stop upon reaching the apical stop to prevent over-instrumentation and perforation . The brushless motor offers ten times the service life of traditional brushed motors, operating with less noise, reduced vibration, and stable cutting power even in curved canals . The ultra-mini contra-angle head measures just 8mm in diameter and 9.7mm in height, rotates 360 degrees, and provides exceptional visibility, particularly when working under a dental microscope . The ergonomic cordless handpiece features a front-centered gravity design, reducing hand fatigue during extended procedures.
