Features of the Woodpecker TFRK File Removal Kit
The Woodpecker TFRK File Removal Kit, developed by Dr. Yoshi Terauchi, is a specialized tool for removing broken or separated files within root canals. This kit offers an innovative solution for complex endodontic challenges.
Main Features:
- Purpose: Specifically designed to remove broken file segments from root canals, maintaining system integrity and minimizing the need for more invasive procedures.
- Components: Includes instruments such as the Micro-Trephine bur, Gates Glidden burs, and the Yoshi Loop, which are minimally invasive and designed to work together to loosen and remove file segments.
- Operation: The process uses specialized burs and a loop system to encircle and extract file segments, combining mechanical and ultrasonic tools for enhanced efficiency.
- Training: Successful use of the TFRK requires training and familiarity with its components and techniques, making it a preferred choice for experienced endodontists.
- Manufacture: Produced by Guilin Woodpecker Medical Instrument Co., Ltd., a renowned manufacturer of dental equipment.

TFRK: The Ultimate Solution for Instrument Retrieval
Given the complexity of root canal situations, the TFRK assembles a variety of tools to ensure effortless and effective instrument retrieval.

Manual TFRK Instrument for Gutta-Percha Removal (TFRK-GPR)
- Made of stainless steel, with a 4% taper
- Can be pre-bent to fit the curvature of the canal
- Delta cones (maximum diameter: 0.35 mm) on both ends
- Used to remove filling material remnants and necrotic pulp tissues in narrow spaces

Micro Explorer TFRK (TFRK-ME)
- Made of stainless steel, with a sharp 0.1 mm diameter tip, double-ended
- 6% taper and smooth surface
- Explores curvatures and reduces coronal irregularities

Micro Trephine Bur (TFRK-MT)
- Internal diameter: 0.5 mm; external diameter: 0.8 mm
- For canal curvatures <15º and coronal diameter of broken instrument 0.45 mm

Modified Gates Glidden Bur #3 (MGG #3)
- Pilot tip is cut to widen the canal to the broken fragment

Martensitic Phase NiTi Rotary Instrument K-Endo (K6 N60 2% L25)
- 60%, 2% taper, NiTi file in martensitic phase at 37ºC


TFRK-Katana Vertical (TFRK-Katana V or E88/ED88) and Horizontal (TFRK-Katana H or E89/ED89)
- Sword-shaped tip to create a 90º semicircular groove on the broken fragment

TFRK-Straight Katana (TFRK-S or E87/ED87)
- Sharp cone-shaped tip to create a 180º semicircular groove

TFRK-Loop (TFRK-L: Yoshi Loop)
- Retrieves the broken file after loosening it with ultrasound

Brownie Polishing Point (TFRK-P)
- Silicone rubber-based tool used to sharpen ultrasonic tips
