This comprehensive instrument set is engineered for posterior lumbar interbody fusion (PLIF/TLIF) procedures with self-stabilizing fusion cages, containing 45 core tools and a complete trial system.
It addresses critical surgical stages—safe access establishment, precise endplate preparation, implant sizing, and reliable cage locking—covering the full workflow from disc space preparation, trial verification, and endplate scraping to final cage implantation and activation of the self-labilizing mechanism.
Manufactured from high-strength stainless steel, key components (e.g., reamers, scrapers) are precision-finished to ensure operational accuracy and durability.
With a core design philosophy of "Safe Access + Endplate Preservation + Self-Stabilizing Locking," the system incorporates modular reamers, vertebral distractors, endplate scrapers, and a dedicated clip fixation system to achieve precise cage placement and immediate stability, effectively reducing subsidence risks.
Through refined instrument coordination and procedural control, the set enables accurate cage positioning and reliable activation of the self-stabilizing mechanism, meeting the demands of lumbar degenerative diseases (e.g., discogenic pain, spinal stenosis, instability) and spondylolisthesis requiring interbody fusion.
Material Excellence
Instruments are constructed from premium stainless steels (05Cr17Ni4Cu4Nb, 420B, 316L, 304), offering high fatigue strength. Electropolished surfaces minimize tissue friction and intraoperative soft tissue damage.
Comprehensive Workflow & Precise Disc Space Preparation
Designed specifically for PLIF/TLIF procedures, the set provides a complete instrument chain from disc space establishment to cage locking. Core components include matched graded reamers (8/10/12/14mm) and corresponding vertebral distractors, enabling safe, controlled gradual expansion and maintained distraction to create an optimal foundation for subsequent steps.
Endplate Preservation & Efficient Graft Bed Preparation
Includes dedicated endplate scrapers (8/10/12/14mm) precisely matched to reamer/distractor sizes. Designed to thoroughly remove cartilage while preserving bony endplate integrity, these tools create an ideal fusion bed and significantly reduce postoperative cage subsidence risks.
Comprehensive Trial System for Precision Implantation
Features an industry-leading trial system covering diameters from 35–55mm and heights from 8–14mm, used with dedicated trial holders. This allows surgeons to accurately assess cage fit, positioning, and disc space compatibility before final implantation—a critical step for surgical success and long-term stability.
Core Self-Stabilizing Locking Mechanism
The set’s key advantage lies in its unique clip fixation system, which includes clip openers (S/M/L), inserters, removers, limit wrenches, pushers, and clip height gauges. This closed-loop system ensures precise notch preparation, reliable clip deployment, and secure locking, providing immediate stability to resist migration and micromotion.
Broad Adaptability & Clinical Value
Designed to meet diverse clinical needs for posterior lumbar fusion, including degenerative conditions (e.g., severe discogenic pain, spinal stenosis, instability) and spondylolisthesis. Its core value lies in enabling accurate cage placement, reliable self-stabilization, and reduced subsidence risk, offering solid initial mechanical support to promote fusion.
Precision Disc Space Management
The coordinated use of graded reamers (8–14mm) and matched distractors enables safe, progressive disc space expansion with maintained height, avoiding single-over-distraction endplate injury. This creates an ideal mechanical environment for cage implantation while reducing intraoperative neural retraction risks.
Endplate Preservation & Fusion Preparation
Size-matched endplate scrapers with protective blade designs thoroughly remove cartilage while preserving bony endplate integrity. This key step directly reduces postoperative subsidence rates and creates a highly viable fusion bed to accelerate biological integration.
Zero-Error Implant Sizing
The industry-leading trial system (5 diameters × 4 heights, 20 total sizes) enables multidimensional dynamic verification of cage fit and positioning. This allows surgeons to perfectly match patient anatomy, avoiding fusion failure risks due to improper sizing and achieving optimal primary implantation.
Reliable Self-Stabilizing Mechanism
The proprietary clip fixation system ensures mechanical precision during cage locking. Clips are inserted to a preset depth under controlled limitation, providing immediate anti-migration stability that surpasses traditional supplemental screw fixation and effectively resists early-stage micromotion.
Improved Long-Term Clinical Outcomes
Endplate preservation techniques reduce subsidence risks, while the self-stabilizing mechanism offers superior biomechanical support. This combination elevates 6-month fusion rates to over 95%, particularly benefiting osteoporotic patients by reducing dependency on ancillary fixation and providing a lifelong solution for degenerative and spondylolisthesis cases.
