All bone preparation tools (cannulated drills, taps, countersinks) and screw insertion instruments feature coaxial hollow designs that strictly follow the guidewire path, eliminating instrument deviation risks and significantly enhancing placement accuracy in deep structures like the femoral neck and pelvis.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLayered Safety Protection Mechanism: \u003c\/strong\u003eThe pressure sleeve integrates a depth-stop function and works with the protection sleeve to isolate rotating instruments from soft tissues. The stopper system provides torque-controlled final locking to prevent screw over-insertion. The pressure handle creates rigid support during drilling, preventing accidental slippage during bone channel preparation.
