I. Core Instrument Components

Channel Establishment Tools
- Positioning Needles & Dilating Sleeves: Establish oblique retroperitoneal working channels with gradient specifications (e.g., Φ5.0mm to Φ20.7mm), minimizing tissue damage through stepwise dilation.
- Protective Sleeve: 22mm diameter with light source interface for optimal surgical field exposure.
Intervertebral Space Preparation Tools
- Adjustable Disc Spreader: Precisely controls disc height, compatible with spacers of varying sizes (110/130/150mm).
- Endplate Curettes & Nucleus Forceps: Remove disc tissue and prepare the fusion bed, featuring blunt edges to protect endplates.
Fusion Cage Implantation System
- Intervertebral Fusion Cage:Material: Titanium alloy or PEEK compliant with ISO 5832 standards, porous surface for bone ingrowth.
  - Design: Wedge/rectangular (e.g., OLIF-V type), some with self-locking clips to reduce displacement.
- Implantation Tools:
  - Impactor: Thread-matched to cages for stable insertion;
  - Adjustment Tools: Impactors/extractors for fine-tuning cage position.
Bone Grafting & Fixation Tools
- Graft Funnel: Efficiently fills autologous or synthetic bone material;
- Percutaneous Pedicle Screw System: Optional posterior fixation to enhance spinal stability.

II. Technical Features

Feature	Implementation
Minimally Invasive	Specialized channel tools (≤22mm) enable 3-5cm incisions, avoiding psoas and neurovascular structures.
Precision Control	Depth-limiting designs (e.g., calibrated positioning needles) + compatibility with optical navigation.
Corrosion Resistance	Chromium-plated surface (≥0.5μm), hardness 37-55HRC, compliant with YY/T0149-2006 standards.
Robotic Compatibility	Supports real-time robotic guidance, reducing surgery time by ≥50%.

III. Clinical Applications

Indications: Degenerative disc disease, Grade I-II spondylolisthesis, degenerative scoliosis correction.
Contraindications: Severe osteoporosis or high-level lumbar lesions (e.g., L1-L2) require cautious evaluation.
