- Reduction Forceps: Serrated jaws and self-centering bone holding forceps for secure manipulation.
- Drill Guides and Sleeves: Multiple drill guide sleeves (φ2.8, φ4.3, φ8), drill guides covering ranges φ2.5-φ3.5 and φ3.2-φ4.5, and reduction sleeves (4.3-2.8).
- Drill Bits: Various diameters including φ2.5, φ2.8, φ3.2, φ4.3.
- Screw Holding Sleeves: Available in sizes φ6 and φ8.
- Screwdrivers: Multiple sizes (SW2.5, SW3.5) and torque-limiting screwdrivers with settings at 1.5 N·m and 4.0 N·m.
- Depth Gauges and Protectors: Depth gauges for φ2.8 and other sizes, protectors for φ2.8 and φ4.3.
- Triangle Target Plates: Plates with angular settings at 90°-50°-40°, 80°-70°-30°, and 100°-60°-20° for accurate alignment.
- Taps: HA3.5 and HA4.5 taps for screw hole preparation.
- Quick Coupling Handle: For efficient instrument assembly and use.

2. Functional Descriptions and Usage
- The guide wires with threaded tips facilitate secure placement and guidance during osteotomy.
- Target moules and positioners ensure precise alignment of plates and screws.
- Reduction forceps with serrated jaws and self-centering features provide stable bone fragment manipulation.
- Drill guides and sleeves maintain drill bit trajectory and protect surrounding tissues.
- Torque-limiting screwdrivers prevent over-tightening, ensuring screw fixation within safe limits.
- Depth gauges assist in measuring screw length to avoid over-penetration.
- Triangle target plates allow angular adjustments to accommodate various anatomical requirements.

3. Critical Parameters and Limitations
- Torque-limiting screwdrivers are calibrated at 1.5 N·m and 4.0 N·m to match screw specifications.
- Drill bits and sleeves are matched by diameter to ensure compatibility and precision.
- The set is specifically designed for pediatric use, implying size and scale considerations.

4. Best Practices and Recommendations
- Use the appropriate guide wire size and type for the specific osteotomy site.
- Employ torque-limiting screwdrivers to avoid screw damage or bone injury.
- Verify alignment using triangle target plates before drilling or screw insertion.
- Utilize protectors and drill guides to minimize soft tissue trauma.
- Regularly check instrument integrity and calibration, especially torque devices.
