Dilator Cannula 6.0/6.35

Model Number: ADB02-IV

Compatible Implants: 6.0 mm percutaneous thoracolumbar screw-rod fixation system (rigid).

Product Introduction

This comprehensive instrument set is designed to support percutaneous thoracolumbar fusion using 6.0 mm screw-rod systems. 


It includes 36 core tools engineered for every surgical stage—from accurate puncture guidance and progressive channel dilation to screw-rod insertion and remote locking. 


Constructed from high-strength stainless steel with enhanced components (such as self-drilling taps and radiopaque localization plates), it ensures smooth manipulation and improved visualization in limited surgical fields. 


The system’s “precise puncture + minimally invasive expansion + in-channel operation” approach significantly reduces muscle disruption—up to 60% less than open surgery—while enabling safe and stable TL fixation, deformity corrections, and spondylolisthesis reduction.



Features

Premium Instrument Materials: 

Constructed from fatigue-resistant stainless steel (05Cr17Ni4Cu4Nb, 420B, 316L, 304) with polished surfaces to minimize tissue friction.


Closed-Loop Surgical Workflow: 

End-to-end tool coverage from puncture guidance to final rod locking reduces workflow breaks and instrument changes.


Accurate Puncture Positioning: 

Integrates a radiopaque targeting plate and rounded-tip guide that enhance precision under fluoroscopy while protecting neurovascular structures.


Stepped Channel Access: 

Includes fascia separators and sequential dilation sleeves (I–III) to gently create a 6.0 mm working channel, preserving soft tissue and accelerating recovery.


Efficient Screw Tract Preparation: 

Self-drilling taps combine drilling and threading, making preparation swift and safe; ball probes verify tract integrity.


Percutaneous Rod Placement Tools: 

Specially designed curved rod benders and delivery tools ensure accurate rod placement via small incisions.


Remote Torque Locking System: 

Ratchet handle and torque driver enable secure screw locking from outside the channel.


Modular System Tray: 

Organized by surgical sequence—localization, dilation, implantation, locking—for efficient setup, cleaning, and storage.



Advantages

High-Precision & Safe Puncture: Fluoroscopy-friendly targeting tools combined with blunt-tip guides significantly reduce the risk of misplacement or neural injury.


Minimized Tissue Trauma: Stepped dilation technique preserves muscular structures, reducing postoperative pain and speeding recovery.


Time-Efficient Workflow: Drilling and threading in one pass with self-drilling taps reduce steps and instrument swaps.


Seamless Rod Placement: Curved rod benders and precision delivery tools ensure accurate alignment while minimizing exposure.


Reliable Fixation: Remote torque drivers offer strong, slip-free screw locking.


Enhanced OR Efficiency: Modular layout streamlines surgical preparation and minimizes human error.
